Introduction:
AFM203T is a low-power and small-volume embedded Wi-Fi + Bluetooth module.
It uses Realtek's highly integrated wireless RF chip RTL8720CM and a small
number of peripheral devices. The chip has built-in 802.11b / g / n Wi-Fi
wireless Built-in ARM Cortex-M4F processing core, with large capacity
(FLASH: 2MB ROM: 384KB) storage space (FLASH: up to 128MB), running space
(SRAM: 256KB) and rich peripheral resources, RTOS system platform in MCU And
the lightweight LWIP protocol, through packaging and optimization of the
SDK, can meet a variety of embedded wireless communication applications.
The official designated development board that matches the AFM203T module
is RTL8720CM-EVB.
