If you already have the Split Single Phase Energy Meter, this pcb adapter, an ESP32 Dev Module pre-programmed with EmonESP (the gateway for EmonCMS), pcb adapter, and ABS Case are the perfect compliment. This is the same adapter and case included in the energy meter kit.
The adapter comes with a special header to allow the ESP32 to sit flat against the pcb, while still being removable. It also has additional holes for each pin on the ESP32, in case you want to add something else.
Also included is an ABS plastic case with pre-drilled holes for the energy meter connections, ESP32 USB, and meter LED lights (in the case lid).
