Green Pill: common questions
What microcontroller does the Green Pill use?
The Green Pill is built around the STM32F103CBT6, from the STM32 family.
How big is the Green Pill PCB?
The Green Pill measures 52.1 × 20.3 mm, has 4 copper layers and is 1.2 mm thick.
How many components are on the Green Pill?
33 components, from 24 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 Green Pill design files?
From the lbthomsen/greenpill 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 Green Pill design in my own project?
It is published under Custom license, which limits how it may be reused; read the license before building on it.
Can I test firmware for the Green Pill without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
