SparkFun Thing Plus Matter – MGM240P board targets the development of applications using the Matter IoT protocol and features the MGM240P module based on Silicon Labs EFR32MG24 Arm Cortex-M33 wireless microcontroller with an 802.15.4 radio for Zigbee and OpenThread plus a Bluetooth Low Energy (BLE) 5.3 radio.
The board also offers two rows of I/Os for upto 21 GPIOs and a Qwiic connector for expansion, another EFRM32 MCU acting as a J-link debugger, a microSD card, and can be powered via USB-C or a LiPo battery.
