ESP32-P4-PC Rev B: common questions

What microcontroller does the ESP32-P4-PC Rev B use?

The ESP32-P4-PC Rev B is built around the ESP32-P4NRWxx(QFN104), from the ESP32 family.

How big is the ESP32-P4-PC Rev B PCB?

The ESP32-P4-PC Rev B measures 60 × 90 mm, has 4 copper layers and is 1.578 mm thick.

How many components are on the ESP32-P4-PC Rev B?

329 components, from 105 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 ESP32-P4-PC Rev B design files?

From the OLIMEX/ESP32-P4-PC 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 ESP32-P4-PC Rev B design in my own project?

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

Can I test firmware for the ESP32-P4-PC Rev B 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.
