2.1 General Description
FC21 is a low-power cost-effective Wi-Fi/BT module based on QCA1023. FC21 supports 1×1 IEEE
802.11a/b/g/n/ac WLAN standards and BT 4.2 (BLE and SPP) and provides a low-power SDIO 3.0
interface for Wi-Fi and UART&PCM interfaces for BT*, and also supports LTE/WLAN coexistence.
FC21 module is a SMT module, with 38 LCC pins and 14 LGA pins. The module package is compact and
the size is only 16.6mm × 13mm × 2.1mm.
1. “*” means under development.
2. BLE function of FC21 module is available.
