Pinci: common questions
What microcontroller does the Pinci use?
The Pinci is built around the PICO, from the RP2040/RP2350 family.
How big is the Pinci PCB?
The Pinci measures 114 × 88.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Pinci?
29 components, from 6 distinct parts. The full bill of materials is listed on this page.
Where can I download the Pinci design files?
From the camrbuss/pinci repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Pinci design in my own project?
Yes, under the terms of its MIT license, which camrbuss chose for the repository.
Can I test firmware for the Pinci without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
