PintApple: common questions

What microcontroller does the PintApple use?

The PintApple is built around the ESP32-S2-WROVER, from the ESP32 family.

How big is the PintApple PCB?

The PintApple measures 40 × 40 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PintApple?

36 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the PintApple design files?

From the camielverdult/PintApple_PCB repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the PintApple design in my own project?

The repository has no license, so all rights stay with camielverdult. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the PintApple 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.
