Pajoniiir-M1: common questions

What microcontroller does the Pajoniiir-M1 use?

The Pajoniiir-M1 is built around the ESP32-P4NRW32X, from the ESP32 family.

How big is the Pajoniiir-M1 PCB?

The Pajoniiir-M1 measures 175.6 × 220.1 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Pajoniiir-M1?

223 components, from 77 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pajoniiir-M1 design files?

From the dvucinozd/Pajoniiir-M1 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Pajoniiir-M1 design in my own project?

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

Can I test firmware for the Pajoniiir-M1 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.
