1.This tiny wifi Module is the perfect replacement for your NRF Radio! It’s a great alternative to the popular NRF, because this lets you talk over Wifi using your MCU’s serial UART via RS232.

2.Wi-Fi Direct (P2P), soft-AP.

3.Built-in TCP / IP protocol stack.

4.Built-in TR switch, balun, LNA, power amplifier and matching network.

5.Built-in PLL, voltage regulator and power management components.

6.802.11b mode + 19.5dBm output power.

7.Built-in temperature sensor.

8.Supports antenna diversity.

9.”Off” leakage current is less than 10uA.

10.Built-in low-power 32-bit CPU: can double as an application processor.

11.SDIO 2.0, SPI, UART.

12.STBC, 1×1 MIMO, 2×1 MIMO.
