Expandable 6 Channel ESP32 Energy Meter Main Board


SKU: EM-6chan Category:


The Expandable 6 Channel ESP32 Energy Meter can read 6 current channels and 2 voltage channels at a time. Much like our Split Single Phase Energy Meter, the 6 channel uses current transformers and an AC transformer to measure voltage and power the board(s)/ESP32. Specifications are very similar to the split single phase meter, but the main board includes a buck converter with a higher output, and an ESP32 dev board can be plugged directly into the board.

Up to 6 add-on boards can stack on top of the main board to allow you to monitor up to 42 channels in high resolution, in real time, all at once!

This product is currently in the prototype stage, so components may change. Lead time on orders is currently a week – they are assembled by hand.

Backorder status

7/13/19 – A revision of the main board and add-on board is currently being worked on to correct an issue with low power output from the onboard power supply. We expect to have a new batch of PCBs in next week. Then another 1-2 weeks to assemble and test the boards.

If you ordered between 7/1 and now, you’ll receive the new revision unless you request the current revision. Orders will be processed in the order that they were received.
