Description

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, they 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.

Ameba RTL8722DM development can be done on Windows, Linux, and Mac operating systems. You can use Arduino IDE to develop applications on RTL8722, and many Arduino examples will run as-is.

Key Features:

Onboard SD Card Slot
Onboard 3.5mm Audio Jack / Microphone
Ultra-low power consumption suitable for IoT applications
Latest high-security architecture with secure boot
Dual Arm powered CPUs for higher performance
Fast wireless speeds with the latest wireless technologies such as Wi-Fi 5GHz and BLE5
Rich I/O peripherals to further expand your projects
Compatible with Arduino IDE with additional Board Support Package
