☆ 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.
