8leds
About the 8leds PCB
8leds is an open source STM32 PCB design by eddyem, published on GitHub. It is a 2-layer board measuring 65 × 41.5 mm, with 40 components from 10 distinct parts.
Its main chip is the STM8S103devbrd, from the STM32 family. Other key parts include the LM1117-5.0. By type, the board carries 16 resistors, 10 connectors, 8 transistors, 3 capacitors, 2 ICs and 1 diode.

8leds: common questions
What microcontroller does the 8leds use?
The 8leds is built around the STM8S103devbrd, from the STM32 family.
How big is the 8leds PCB?
The 8leds measures 65 × 41.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the 8leds?
40 components, from 10 distinct parts. The full bill of materials is listed on this page.
Where can I download the 8leds design files?
From the eddyem/STM8_samples repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the 8leds design in my own project?
The repository has no license, so all rights stay with eddyem. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the 8leds 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.
