Pmi 2023: common questions

What microcontroller does the Pmi 2023 use?

The Pmi 2023 is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Pmi 2023 PCB?

The Pmi 2023 measures 85 × 71.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pmi 2023?

266 components, from 49 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pmi 2023 design files?

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

Can I use the Pmi 2023 design in my own project?

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

Can I test firmware for the Pmi 2023 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.
