2 Product Overview
AF20 is an automotive grade Wi-Fi and Bluetooth module with low power consumption. It is a single-die
wireless local area network (WLAN) and Bluetooth combo solution supporting IEEE 802.11 a/b/g/n/ac
Wi-Fi standards and Bluetooth 5.0 standard, which enables seamless integration of Wi-Fi and Bluetooth
Low Energy technologies. And it has DFS function and supports both Master and Slave scenarios.
AF20 supports a low-power SDIO 3.0 interface for WLAN, and UART and PCM interfaces for Bluetooth,
and also supports LTE/Wi-Fi & Bluetooth coexistence interface. It is designed to be used in conjunction
with Quectel automotive grade LTE module AG35 so as to provide AG35 with Wi-Fi and Bluetooth
functions. Connection between AF20 and AG35 via the coexistence interface helps reduce the
interference between LTE signal and Wi-Fi/Bluetooth signal.
AF20 is an SMD type module with a compact form factor of 17.2 mm × 15.2 mm × 2.26 mm. It can be
embedded in your applications through the 52 LGA pins.
