MecProInverter: common questions

What microcontroller does the MecProInverter use?

The MecProInverter is built around the ESP32-S3-MINI-1-N8, from the ESP32 family.

How big is the MecProInverter PCB?

The MecProInverter measures 104 × 168 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the MecProInverter?

172 components, from 68 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the MecProInverter design files?

From the Eg0st/MecProInverter repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the MecProInverter design in my own project?

The repository has no license, so all rights stay with Eg0st. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the MecProInverter without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
