Ameba D: Ultra-Low-Power Versatile IoT Solution (RTL8722DM)

The RTL8722DM multi-functional integrated IoT single chip has very high security level architecture and low power consumption. Dual-band Wi-Fi and Bluetooth 5 Mesh transmission achieves long-distance transmission and anti-interference performance across various wireless devices. LCD Panel support and patented ultra-low audio latency features also make the RTL8722DM the best IoT solution for smart door lock and IoT Wi-Fi audio/entertainment devices. An integrated global IoT ecosystem allows customers to develop advanced IoT applications with highest security.

Compared with Espressif ESP32 Ameba D provide dual band WiFi +BLE 5, has an USB OTG port and it's dual core Cortex M4/M0; on top of that, 4MB of PSRAM is inside.

I don't find too many information regarding where to buy modules and the chipset but what I find is listed here:

SDK: https://github.com/ambiot/ambd_sdk
associated design documents and EVK here: https://buy-lcd.com/development-board-millimeter-wave-radar-smart-home-rtl8722dm-88-pin-p0321.html
other informations here: https://www.amebaiot.com/en/amebad/

seems to be a very nice chip this is the reason why I share.
