module. The DUT of the evaluation board
DIP Switches 3 ea 10-pin DIP Switches used for disconnecting the evaluation boards connections
to the various on board features (i.e. LEDs, switches, etc.).
ISP Switch ISP Mode Switch: 2-position slide switch to control ISP mode
‘ISP’ position is used for downloading application firmware to the ZICM2410.
For normal operation, the switch should be set to the ‘NORMAL’ position.
RESET Switch Button switch to reset the device MPU (Active Low)
General Purpose LEDs Four Indicator LEDs for GPIO output tests
Test Ta ct Switc hes
Push Button Switches connected to General Purpose I/O (GPIO) Ports:
When a button is pressed, the signal ‘0’ is applied to the corresponding port pin.
Otherwise, a value of ‘1’ is applied. Switch #3 and #4 can be configured as external
interrupts to the 8051 microcontroller.
Battery Holders Holder for 2 ea. 1.5 Volt Type AA Batteries
DC JACK Input for a 5.0 – 9.0 Volt DC Power Suppl y
POWER Switch
This three-position slide switch is used to select the power source for the evaluation
board. In the position ‘VREG’, power is supplied either through the USB port or
from a power supply inserted in the DC Jack. In the ‘VBAT’ position, batteries provide
the power.
Power Indicator LED LED indicates when DC power is turned on.
USB Port Port to connect the evaluation board through a USB cable to a PC.
ADC Variable Resistors Variable Resistors for testing ADC functions in the
ZICM2410P0
module
Current Monitor pins For measuring operating current of the module under various conditions
5.2.1 ZICM2410-EVB3 Power Supply Options
The three position slide switch operates in accordance with the settings given in Table 5. The
Power Indicator LED (red) illuminates when power is applied to the evaluation board through
any of the methods.

Position
1 VREG VUSB: 5.0 V
DC Jack: 5.0 – 9.0 V
In this position the evaluation board and
module are either powered from the USB
interface or through the DC Jack from an
external supply.
2 VBAT 3.0 V In this position the evaluation board and
module are powered from the two 1.5 V Type
AA batteries.
3 VREG + J4 ZIC2410-EVB3: 5 V
ZICM2410: 2.1 – 3.0V
In this position the evaluation board is
powered via either the USB interface or
through the DC Jack. The ZICM2410
module is powered externally via the J4
header. See the
“ZICM2410-EVB3
Evaluation Board Hardware Reference
Guide”
for further details.
