Olimex ESP32-C6-EVB User Manual

User manual for Olimex ESP32-C6-EVB, a Wi-Fi 6/BLE/802.15.4 development board with four 10A relays, four opto-isolated inputs, and wide 8-50VDC power support.

View design document

Overview

The ESP32-C6-EVB is an open-source evaluation board powered by the Espressif ESP32-C6-WROOM-1-N4 module. It features a 32-bit RISC-V single-core microprocessor supporting 2.4 GHz Wi-Fi 6, Bluetooth 5 (LE), and IEEE 802.15.4 (Zigbee and Thread). The board is designed for industrial and home automation, providing four 10A/240VAC relays and four opto-isolated DC inputs. Connectivity options include two UEXT expansion connectors (standard and JST), a GPIO header (EXT1), and a USB-C port for power, programming, and JTAG debugging. It operates on a wide input voltage range of 8-50VDC and is compatible with ESP-PROG for external serial debugging and firmware restoration. This manual provides hardware layout, detailed pinout descriptions, and electrical schematics.

Use Cases

  • Industrial IoT gateway development
  • Smart home automation and relay control
  • Wireless sensor networks with Zigbee or Thread
  • Remote monitoring using Wi-Fi 6 connectivity
  • Evaluation of ESP32-C6 wireless protocols
