Olimex ESP32-C6-EVB

The Olimex ESP32-C6-EVB is a WiFi 6 (IEEE 802.11ax) and Bluetooth-enabled development board using the Espressif ESP32-C6, which integrates 2.4 GHz, Wi-Fi 6, Bluetooth 5 (LE) and the 802.15.4 low-rate wireless personal area network (LR-WPAN).

The board includes four 10A/240VAC relays, four opto-isolated inputs for DC voltage (up to 30VDC) and a USB-C connector for power/programming. It also offers a wide power input range via the barrel jack connector, accepting 8-50V input.

This board is perfect for stand-alone usage but can also be attached to any existing hardware project to augment it with 2.4GHz Wi-Fi 6 and Bluetooth LE 5.3 capabilities.

Please note: the relays may change between batches (colour/brand) however they are rated the same. The LEG-5F relays on recent batches may only show 120 VAC 15A, however this is just because the small relay surface does not allow all ratings to be shown.
