Bulgarian open {hardware} specialist Olimex has introduced a compact, low-cost, breadboard-friendly improvement board designed for folks trying to experiment with Matter units and the Web of Issues: the ESP32-H2-DevKit-LiPo.
Constructed across the Espressif ESP32-H2 microcontroller, the Olimex ESP32-H2-DevKit-LiPo provides a single 32-bit microcontroller core constructed across the free and open-source RISC-V instruction set structure operating at as much as 96MHz, 32kB of static RAM, 128kB of on-chip ROM, 4kB of low-power RAM (LPRAM), and 4MB of flash reminiscence.
There are 19 general-purpose enter/output (GPIO) pins and peripherals together with an analog to digital converter (ADC), SPI, I2C, I2S, and UART buses, and pulse-width modulation (PWM) help.

All these pins and peripherals are introduced out to breadboard-friendly 0.1″ pin headers on the Olimex board, nevertheless it’s the module’s wi-fi connectivity which makes it of actual curiosity to the Web of Issues fanatic. The module embrace help for Bluetooth 5 Low Vitality and IEEE 802.15.4 low-rate wi-fi private space community (LR-WPAN) help — together with Thread, Zigbee, and the brand new Matter vendor-neutral commonplace.
The board additionally contains two USB Sort-C connectors — one in all which matches to a USB-UART bridge for programming and debugging with the opposite linked on to the ESP32-H2 module — a lithium-polymer (LiPo) battery connector with charging circuit, a Qwiic/STEMMA QT connector for solder-free enlargement together with an Olimex UEXT connector for similar, bodily reset button, and user-programmable button enter and LED output.
The ESP32-H2-DevKit-LiPo is now out there to order on the Olimex retailer at €8 (round $8.66), with transport anticipated to start on the finish of the month; the {hardware} design recordsdata can be found within the mission’s GitHub repository underneath the reciprocal GNU Common Public License 3.
