2 Overview
This document describes the BD-SDMAC.
BD-SDMAC is a dual-band 1x1 802.11a/b/g/n/ac plus Bluetooth 4.1+HS “Smart Ready”
SDIO module based on the Silex SX-SDPAC/Qualcomm Atheros QCA9377 System-on-Chip
(SoC). The BD-SDMAC is a pre-certified module with a compact 13mm x 18mm footprint.
BD-SDMAC provides an SDIO3.0 interface for WLAN and a hi-speed UART interface for
BT. The module can be evaluated with any Boundary Devices single board computer and driver
support is integrated in all Boundary Devices kernels.
Features
IEEE802.11a/b/g/n/ac compatible (2.4 GHz, 5 GHz)
5 GHz : Support 20/40/80 MHz bandwidth mode (Link rate 433 Mbps)
2.4 GHz : Support 20/40 MHz bandwidth mode (Link rate 200 Mbps)
Bluetooth 4.1 BR/EDR/LE Smart Ready compatible. Backward-compatible to Bluetooth
1.x, 2.x, 3.0, 4.0
SDIO3.0 as the Wireless LAN host interface
UART as the Bluetooth host interface
u.FL connector for external antenna
Single antenna or optional dual antenna diversity controlled by software and
signal pins
Worldwide acceptance: FCC (USA), IC (Canada), ETSI (Europe)
Modular certification allows reuse of FCC ID and ETSI certification without repeating
the expensive testing on end product
+3.3V main power supply and 1.8V IO power supply
ROHS Compliant
