QPocketPCR Main: common questions
What microcontroller does the QPocketPCR Main use?
The QPocketPCR Main is built around the ESP32-S2-WROVER, from the ESP32 family.
How big is the QPocketPCR Main PCB?
The QPocketPCR Main measures 82.5 × 140 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the QPocketPCR Main?
96 components, from 41 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 QPocketPCR Main design files?
From the GaudiLabs/qPocketPCR 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 QPocketPCR Main design in my own project?
Yes, under the terms of its GPL-3.0 license, which GaudiLabs chose for the repository.
Can I test firmware for the QPocketPCR Main 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.
