The Maker Go ESP32-C6-EVB is an open-source development board built upon the ESP32-C6 module. It integrates four relays and four opto-isolated inputs and supports multiple wireless technologies including Wi-Fi 6, Bluetooth Low Energy 5.0, and Thread/Zigbee.
The Espressif ESP32-C6 on the development board is a single, RISC-V system-on-chip with 2.4GHz Wi-Fi 6 (802.11ax), Bluetooth 5 (LE), and Thread/Zigbee (802.15.4). It is integrated into the ESP32-C6-WROOM-1-N4 module with an onboard PCB antenna, 4MB of SPI flash, and 23 GPIOs.
We have seen a fair amount of ESP32-C6 boards recently, including the SparkFun Thing Plus, WeAct ESP32-C6-Mini, ESP32-C6-Pico, and the ePulse Feather C6.

The Maker Go relay board is very similar to the open-source Olimex ESP32-C6-EVB dev board released last year. However, it is slightly cheaper at about $13 and uses a different interface and connector layout. EasyEDA schematics, Tasmota firmware, and a sample program can be downloaded from the company’s website. Our best guess is that Maker Go based their dev board on the Olimex ESP32-C6-EVB (same name and everything), but they didn’t credit Olimex anywhere on the Tindie page or their website. Some tools allow people to import KiCAD to EasyEDA so maybe that’s what they used and made some modifications after that.
The Maker Go ESP32-C6-EVB relay board can be purchased for $13.41 on Tindie, and it sells on Aliexpress for $10.75 and up along with other relay boards from the company. You can also get a plastic shell for the development board that leaves the essential interfaces exposed – optocoupler inputs, relays, USB-C programming, and power jack – for $6.
