About the Clk led matrix PCB

Clk led matrix is an open source STM32 PCB design by kingovchouffe, published on GitHub. It is a 4-layer board measuring 89.7 × 33.2 mm, with 55 components from 21 distinct parts.

Its main chip is the STM32C071KBUx, from the STM32 family. Other key parts include the AMS1117-3.3 and ATGM336H-5N31. By type, the board carries 22 resistors, 10 connectors, 9 capacitors, 7 diodes, 3 ICs and 2 switches.

It belongs with the displays & leds designs in this gallery.

From the project

This repository contains KiCad hardware designs for a GNSS-oriented clock and LED matrix display. The primary design combines an STM32C0-series controller with an ATGM336H GNSS receiver; separate files capture a CH32V003-based 5x7 display design.

Clk led matrix: common questions

What microcontroller does the Clk led matrix use?

The Clk led matrix is built around the STM32C071KBUx, from the STM32 family.

How big is the Clk led matrix PCB?

The Clk led matrix measures 89.7 × 33.2 mm, has 4 copper layers and is 1.600198 mm thick.

How many components are on the Clk led matrix?

55 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the Clk led matrix design files?

From the kingovchouffe/clk_led_matrix repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Clk led matrix design in my own project?

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

Can I test firmware for the Clk led matrix 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.
