Olimex ESP32-C6-EVB is an open-source hardware board based on an ESP32-C6 wireless module with 2.4 GHz WiFi 6, Bluetooth LE, and Zigbee connectivity, and offering four relays and four opto-isolated inputs, as well as further expansion via two UEXT connector.
So far we had a limited amount of third-party ESP32-C6 boards, with Espressif making their own module and development board available in January, and 01Space launching a tiny ESP32-C6 board in April, a time when a lot of software work was still needed. But the ESP-IDF v5.1 with ESP32-C6 support is nearing release (now RC2), and the Olimex board may mark the start of greater availability of ESP32-C6 hardware with stable/usable firmware.
ESP32-C6-EVB specifications:
- Wireless module – ESP32-C6-WROOM-1-N4 module with
- Espressif Systems ESP32-C6 single core 32-bit RISC-V processor @ 160 MHz with 2.4 GHz WiFi 6 1T1R with Target Wake Time (TWT) support, Bluetooth LE 5.0, and 802.15.4 radio for Zigbee, Thread, Matter, 2.4GHz proprietary
- Storage – 4MB SPI flash
- PCB antenna
- USB – 1x USB Type-C port for programming and JTAG debugging
- I/Os and expansion
- 4x relays (10A/240VAC)
- 4x opto-isolated inputs for DC voltage up to 30VDC
- 2x UEXT connectors
- Extension GPIO connector
- Programming connector
- Misc – Reset and user buttons
- Power Supply – 6-50V DC wide range supply voltage via DC jack
- Dimensions – TBD (Four mount holes)
Since the ESP32-C6-EVB is an open-source hardware board, Olimex will eventually release the schematic in PDF format and the KiCAD hardware design files, provide a user manual, as well as a demo project with source code. But at the time of writing, none of the links are up, and I expect those to become available shortly after the board starts shipping on June 30.
Olimex is already taking pre-orders for the ESP32-C6-EVB board for 15 Euros, and shipping should start by the end of the month.
