Green Pill: common questions
What microcontroller does the Green Pill use?
The Green Pill is built around the STM32F103C8Tx, from the STM32 family.
How big is the Green Pill PCB?
The Green Pill measures 51.2 × 70.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Green Pill?
29 components, from 20 distinct parts. The full bill of materials is listed on this page.
Where can I download the Green Pill design files?
From the IsmaelLopesSilva/Eletronica repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Green Pill design in my own project?
The repository has no license, so all rights stay with IsmaelLopesSilva. Use it as a reference, and ask the author before reusing the design.
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.
