☆ INTRODUCTION
Ameba D RTL8722DM is a highly integrated single-chip with low power consumption mechanism for IoT (Internet of Things). It combines an arm® new architecture Armv8M KM4 MCU, Wi-Fi, Bluetooth and provides a bunch of configurable GPIOs which are configured as digital peripherals for different applications and control usage.
RTL8722DM-EVB (71 Pin) Wireless Dev Board is a convenient development kit for makers. It separate into 2 boards, the small one- AFM431T WiFi+Bluetooth Module ( This IoT module can be purchased separately)
on the top is main mother board with all functions included, and the other on the bottom is similar to Arduino UNO form factor size which provides the development interface CMSIS-DAP mode and J-LINK debugger mode.
