M5Stack Unit Gateway H2 – A tiny ESP32-H2 Thread/Zigbee gateway selling for $6.50

M5Stack Gateway H2

M5Stack’s Unit Gateway H2 is a small Thread/Zigbee gateway powered by the ESP32-H2-MINI-1 module with an 802.15.4 radio for Zigbee 3.0, Thread 1.3, and Matter connectivity. The Unit Gateway H2, also known as Gateway H2 Unit…, can operate as a gateway (e.g. a Thread Board Router) or a terminal device that communicates with a M5Stack device via serial/UART through the Grove interface.  It also features a USB-C port for power, firmware flash, and debugging. M5Stack says it’s suitable for smart homes, environmental monitoring, sensor networks, and low-power wireless communication nodes.   M5Stack Gateway H2 Unit specifications: Wireless module – ESP32-H2-MINI-1-N2 SoC – Espressif Systems ESP32-H2 CPU – 32-bit RISC-V SoC clocked at up to 96 MHz RAM and storage – 320 KB SRAM, 128 KB ROM, 4 KB LP memory Wireless – 802.15.4 radio with Zigbee 3.0, Thread 1.3, and Matter support. (Note: the ESP32-H2 also supports Bluetooth 5.2 LE/Mesh, […]

Silicon Labs MG26 development kits and SoCs are now available for Matter and multiprotocol Smart Home applications

xG26 PK6028A MG26 development kit

Silicon Labs MG26 is a new family of Arm Cortex-M33 wireless SoCs designed for Matter or multiprotocol Smart Home applications that provide an update to the MG24 with more memory and storage, additional GPIO, a 4×40 LCD controller, and an integrated AI/ML accelerator. We first covered the new wireless microcontroller family in April 2024, but the company has now published a new press release announcing the general availability of the MG26 microcontrollers, and I also noticed some development kits were now available, so we’ll check those out in this post. Silicon Labs MG26 specifications A reminder of the SoC specifications with highlights in bold showing the improvements or differences against the MG24 family: MCU core – Arm Cortex-M33 @ 78.0 MHz with DSP instruction and floating-point unit Memory – Up to 512 kB RAM data memory Storage – Up to 3200 kB flash program memory AI/ML accelerator – Matrix Vector […]
