P4hil: common questions
What microcontroller does the P4hil use?
The P4hil is built around the C22387510, from the ESP32 family.
How big is the P4hil PCB?
The P4hil measures 81.3 × 61 mm, has 4 copper layers and is 1.61668 mm thick.
How many components are on the P4hil?
206 components, from 46 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 P4hil design files?
From the tannewt/p4hil 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 P4hil design in my own project?
The repository has no license, so all rights stay with tannewt. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the P4hil 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.
