Ameba RTL8722DM Mini Board (AMB 23) is a devkit for a different family of WiFi/BLE-integrated chipsets from RealTek. As more chip companies come out with their “All in One IoT” platforms, we like to stock a dev kit for folks who are interested in experimentation. Support for this chipset is not as complete as Espressif or Arduino boards, but it looks like an inexpensive and easy way to get started with the RTL8722 if you’d like to try it out!
This board integrates the RTL8722DM SoC which is the latest generation SoC of the Ameba IoT solution family, and it is powered by a high-performance 32-bit dual MCU with a new architecture from Arm; an Armv8M (Cortex-M33 instruction set compatible) running at up to 200MHz and an Armv8M (Cortex-M23 instruction set compatible) running at up to 20MHz.
This SoC also integrates the latest high-security architecture (Trustzone-M Security) with ultra-low power consumption suitable for IoT (Internet of Things) applications. RTL8722DM also integrates the latest wireless technologies such as dual-band Wi-Fi (2.4GHz/5GHz) and Bluetooth Low Energy (BLE5) Mesh.
Ameba RTL8722DM Mini Board features rich I/O peripherals such as a high-speed SDIO and USB interface, audio codec, key-scan and touch key, LCD panel controller, embedded 4.5MB SRAM (512KB SRAM + 4MB PSRAM), and configurable GPIOs that can function as digital peripherals for various applications.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
