Green Pill stlink: common questions

What microcontroller does the Green Pill stlink use?

The Green Pill stlink is built around the STM32F103C8T6, from the STM32 family.

How big is the Green Pill stlink PCB?

The Green Pill stlink measures 55 × 23 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Green Pill stlink?

42 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the Green Pill stlink design files?

From the UofA-SPEAR/pcb_designs repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Green Pill stlink design in my own project?

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

Can I test firmware for the Green Pill stlink 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.
