About the Controller PCB

Controller is an open source STM32 PCB design by antonloof, published on GitHub. It is a 2-layer board measuring 105 × 42 mm, with 41 components from 17 distinct parts.

Its main chip is the STM8L101F3P, from the STM32 family. Other key parts include the 74HCT541. By type, the board carries 18 resistors, 11 capacitors, 8 switches, 2 ICs and 2 connectors.

From the project

testing to drive tls3001 leds with a pico

Summary: Manchester encoded data: 1 => 10 0 => 01 Timing is critical, keep constant period! When sleeping put data low!

Sync frame: "1"15+"0001"+"0"11 (111111111111111000100000000000)

Reset frame: "1"*15 + "0100" (1111111111111110100)

Data frame header: "1"*15 + "0010" (1111111111111110010)

Data content: "0"+"x"12 + "0"+"x"12 + "0"+"x"*12 where x is the rgb data to send total 39 bits per led repeat this for all leds in series

The KiCad project lives in the antonloof/eta_game_system repository on GitHub; these links point at the commit this page was built from.

Controller: common questions

What microcontroller does the Controller use?

The Controller is built around the STM8L101F3P, from the STM32 family.

How big is the Controller PCB?

The Controller measures 105 × 42 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Controller?

41 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the Controller design files?

From the antonloof/eta_game_system repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Controller design in my own project?

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

Can I test firmware for the Controller 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.
