Multifunctional board for RISC-V Espressif ESP32-H2
2023-12-17 01:10
Bulgarian open source hardware company Olimex has unveiled a new board design.
The ESP32-H2 comes after the company moved from proprietary instruction set architectures to the free and open RISC-V architecture, replacing its conventional Tensilica Xtensa LX6 or LX7 cores with 32-bit RISC-V cores. The ESP32-H2 offers a single RISC-V core running at up to 96 MHz, 320 KB of static random access memory (SRAM) and 128 KB of on-chip flash, as well as 4 MB of off-chip and 4 KB of low-power memory.
Designed for the Internet of Things (IoT), the ESP32-H2 radio unit forgoes Wi-Fi in favor of a 2.4GHz transceiver that supports Bluetooth 5 Low Energy BLE) and IEEE 802.15.4 protocols including Thread, Zigbee, and Matter. The module also includes a number of peripherals, including a security block with SHA, AES and ECDSA acceleration, a temperature sensor, a real-time clock, SPI, I2C, I2S, TWAI and UART buses, and general-purpose input/output (GPIO) devices, including an analog-to-digital converter (ADC).
The board for the module has two USB Type-C ports - one for access to the microcontroller's serial debug port and JTAG debugger, and one for programming and power. There is a connector for a lithium polymer battery with charging circuit, physical reset buttons and bootloaders, and Qwiic/STEMMA QT and UEXT connectors for connecting external hardware.
More details can be found on the Olimex blog. A sales launch date has not yet been announced.
