Prototyping area with 10 x 20 = 200 PADs - 100mil spacing to ease through-hole component prototyping - Square PADs to ease SMD passive component prototyping - Fits mini solderless breadboards for fast and simple prototyping Xplained Pro hardware identification system Can be used as an vertical extender for Xplained Pro standard extionsion modules Support for Xplained series extension modules Kit Overview The Atmel PROTO1 Xplained Pro board is a generic prototyping extension board for the Xplained Pro platform. It connects to any standard extension header on any Xplained Pro MCU board and thus is offers an easy way to do prototyping with the Xplained Pro platform. It can be used to prototype small designs that can be connected to the Xplained Pro MCU series of kits. The prototype area consist of 200 free square pads with 100mil (2.54mm) spacing that can be used to protoype both through-hole components as well as SMD components like resistors, capacitors, and inductors. The protoyping area is marked with letters and numbers on both sides of the board so it is easy to identify each pad with a coordinate to make precise connections. Power in the form of GND and VCC_TARGET (is distributed horizontally along the lower side of the prototype for easy connection across the board. The prototyping area offers also space to fit a solderless breadboard on top. A popular size of these boards is 45mm x 35mm and provides 170 solderless points. The top section of the board is a break-away section that can be used to connect external power to the Xplained Pro MCU bord with a screw terminal block. It also distributes GND, VCC_TARGET, and VCC_USB (+5V) from the Xplained Pro MCU board that can easily be connected to the prototyping area. The lower section of the board has a right angled header on the left side that connects to Xplained Pro MCU boards, a prototyping area in the middle and another connector on the right side that provides easy access to the extension header signals. The vertical header on the right hand side can be used to connect the extension signals to the prototyping area or to connect extension modules of the Xplained platform e.g. sensor boards, or the RZ600 radio kit. More information on how to connect Xplained extensions is available in the hardware users guide section of this guide. The Atmel PROTO1 Xplained Pro supports the Xplained Pro hardware identification system.

Xplained Pro Xplained Pro is an evaluation platform that provides the full Atmel microcontroller experience. The platform consists of a series of Microcontroller (MCU) boards and extension boards, which are integrated with Atmel Studio, have Atmel Software Framework (ASF) drivers and demo code, support data streaming, and more. Xplained Pro MCU boards support a wide range of Xplained Pro extension boards, which are connected through a set of standardized headers and connectors. Each extension board has an identification (ID) chip to uniquely identify which boards are connected to an Xplained Pro MCU board. This information is used to present relevant user guides, application notes, datasheets, and example code through Atmel Studio. 3.1. Hardware Identification System TM All Xplained Pro compatible extension boards have an Atmel ATSHA204 CryptoAuthentication chip mounted. This chip contains information that identifies the extension with its name and some extra data. When an Xplained Pro extension is connected to an Xplained Pro MCU board the information is read and sent to Atmel Studio. The Atmel Kits extension, installed with Atmel Studio, will give relevant information, code examples, and links to relevant documents. The table below shows the data fields stored in the ID chip with example content. Table 3-1.

Headers and Connectors This chapter describes the implementation of the relevant connectors and headers on PROTO1 Xplained Pro. 4.2.1. PROTO1 Xplained Pro Extension Headers The PROTO1 Xplained Pro has two 20-pin headers. One is angled (left side of the board) and is intended to be connected to a Xplained Pro MCU board, standard extension header. The other is a vertical header (right side of the board) that can be used to connect signals to the prototype area or to attach other extension modules to it. The signals are identical on both, except for the ID signal, which is slightly different. The rest of the signals follow the standard Xplained Pro extension header pin-out. The different ID signals are described in section PROTO1 Xplained Pro ID System. Atmel PROTO1 Xplained Pro [USER GUIDE] Atmel-42080C-PROTO1-Xplained-Pro-Hardware_User Guide-03/2016 9 Figure 4-1. Extension Header Connector Related Links Xplained Pro Standard Extension Header on page 6 4.2.2. Power Header The four pin power header on the PROTO1 Xplained Pro extension board is used to probe the voltage on the board. The pins of the header are marked in silk screen with VCC for target voltage and GND for ground. Caution: The two pin power header should not be used to apply power to the PROTO1 Xplained Pro. The board will get power from the Xplained Pro MCU board through the 20-pin extension connector. Table 4-2. Power Header 4.2.3. Silk screen marking Description VCC Target voltage, main voltage of the PROTO1 Xplained Pro extension board GND Ground EP5V0 External 5.0V supplied to the Xplained Pro MCU board VP5V0 VCC_USB External Power Terminal Block Header The PROTO1 Xplained Pro features a two pin terminal block header to connect external power to the board. To connect a cable to it, just insert it (remove the insulation from the end first) through the holes at the bottom entry of the connector. An internal spring blade will lock the wire in place. To release it again, Atmel PROTO1 Xplained Pro [USER GUIDE] Atmel-42080C-PROTO1-Xplained-Pro-Hardware_User Guide-03/2016 10 insert a small screwdriver or similar into the top hole to release the tension of the spring blade and pull the wire out. This is shown in the figure below. Table 4-3. Terminal Block Header Silk screen marking Pin on terminal block connector EP5V0 1 GND 2 Table 4-4. Terminal Block Header 4.3. PROTO1 Xplained Pro ID System The PROTO1 Xplained Pro board has the Xplained Pro hardware identification system implemented. When the board is connected via an Atmel Xplained Pro MCU board to Atmel Studio it will be identified and relevant information like the user guide will be shown. By default the ID device on the board is connected to the right angled extension header and the ID X pin of the vertical extension header on the right side of the board is unconnected. It is however possible to connect the ID X signal to the right angled extension header with the hardware changes described below. This makes it possible to use the PROTO1 Xplained Pro as an right angle extender for extension boards and Atmel Studio will recognize their ID. In order to do so, the PROTO1 Xplained Pro ID needs to be disconnected and the ID X signal needs to be connected. To disconnect the PROTO1 Xplained Pro ID just cut the cut-strap marked as ID PROTO1 (see figure below) on the bottom side of the PCB. Figure 4-2. ID PROTO1 To connect the ID X signal, solder a 0 resistor or a piece of wire to the open strap marked as ID X (see figure below) on the bottom side of the PCB. Atmel PROTO1 Xplained Pro [USER GUIDE] Atmel-42080C-PROTO1-Xplained-Pro-Hardware_User Guide-03/2016 11 Figure 4-3. ID X Now any connected Xplained Pro extension modules that are plugged into the vertical extension header on the right side of the board will be detected by Atmel Studio, the PROTO1 Xplained Pro extension board will not longer be detected. 4.4. Connecting the PROTO1 Xplained Pro The lower part of the PROTO1 Xplained Pro board can be connected to all Xplained Pro MCU evaluation kits standard extension headers. If the upper break-off part, containing the additional power section, should be used, it is required to connect the board to the EXT1 header in order to connect to the Power header as well (see figure below). To break off the upper section of the board break it along the V-CUT score line across the PCB. Figure 4-4. Example Connection The connection indicated below may cause the power plug to short some of the EXT1 pins if it is connected externally. To avoid this, either move the PROTO1 Xplained Pro to another extension connector or break away the power section. Atmel PROTO1 Xplained Pro [USER GUIDE] Atmel-42080C-PROTO1-Xplained-Pro-Hardware_User Guide-03/2016 12 Figure 4-5. Not Recommended PROTO1 Xplained Pro Connection Info: Note that any remaining mouse bite residues should be filed or cut away for optimum fit. 4.4.1. Connecting Xplained Extension Boards It is also possible to interface legacy Xplained top-modules via the PROTO1 Xplained Pro board. The signal layout on the extension connector below the white line, i.e. pins 11 - 20 is identical to the J1 connector (communication connector) on the legacy Xplained series MCU boards. Atmel PROTO1 Xplained Pro [USER GUIDE] Atmel-42080C-PROTO1-Xplained-Pro-Hardware_User Guide-03/2016 13 Figure 4-6. External Connector So for legacy Xplained series top-modules that only uses this connector can be attached. Note that the extension connector on the Xplained Pro MCU board might not have all signals available due to lack of pin resources. This needs to be checked for each case. A mounting example is shown in the picture below with a sensor board. Figure 4-7. Xplained Series Sensor Board Mounted on PROTO1 Xplained Pro 4.4.2. Using PROTO1 Xplained Pro With a Solderless Breadboard It is possible to mount a 170 Tie-points solderless breadboard (size 47mm x 35mm) on to the prototype section on the PROTO1 Xplained Pro board to ease prototyping as seen in the picture below. It lacks any GND/VCC rails so they needs to be connected directly. These boards can be found at a low cost from several vendors on the internet.

Hardware Revision History and Knonwn Issues 5.1. Identifying Product ID and Revision The revision and product identifier of Xplained Pro boards can be found in two ways; either through Atmel Studio or by looking at the sticker on the bottom side of the PCB. By connecting an Xplained Pro MCU board to a computer with Atmel Studio running, an information window will pop up. The first six digits of the serial number, which is listed under kit details, contain the product identifier and revision. Information about connected Xplained Pro extension boards will also appear in the Atmel Kit's window. The same information can be found on the sticker on the bottom side of the PCB. Most kits will print the identifier and revision in plain text as A09-nnnn\rr, where nnnn is the identifier and rr is the revision. Boards with limited space have a sticker with only a QR-code, which contains a serial number string. The serial number string has the following format: "nnnnrrssssssssss" n = product identifier r = revision s = serial number The product identifier for PROTO1 Xplained Pro is A09-1890. 5.2. Revision 2 Revision 2 of PROTO1 Xplained Pro is the initial released version. PROTO1 Xplained Pro boards with a serial number that ends with a number lower than 19048 may have a wrong revision programmed into the Xplained Pro ID chip. This will only affect the information displayed by the Atmel Kits extension in Atmel Studio. It will not affect the operation of the board.
