PowerMonitor-ControllerBoard: common questions

What microcontroller does the PowerMonitor-ControllerBoard use?

The PowerMonitor-ControllerBoard is built around the ESP32-PICO-D4, from the RP2040/RP2350 family.

How big is the PowerMonitor-ControllerBoard PCB?

The PowerMonitor-ControllerBoard measures 66 × 44 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the PowerMonitor-ControllerBoard?

51 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the PowerMonitor-ControllerBoard design files?

From the LedgerProject/sensix-power-monitor repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the PowerMonitor-ControllerBoard design in my own project?

Yes, under the terms of its MIT license, which LedgerProject chose for the repository.

Can I test firmware for the PowerMonitor-ControllerBoard without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
