PTR mega hardware: common questions
What microcontroller does the PTR mega hardware use?
The PTR mega hardware is built around the ESP32-S3FN8, from the ESP32 family.
How big is the PTR mega hardware PCB?
The PTR mega hardware measures 31 × 100 mm, has 4 copper layers and is 1.26 mm thick.
How many components are on the PTR mega hardware?
203 components, from 107 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 PTR mega hardware design files?
From the PTR-projects/PTR_mega_hardware 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 PTR mega hardware design in my own project?
Yes, under the terms of its MIT license, which PTR-projects chose for the repository.
Can I test firmware for the PTR mega hardware 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.
