About the KEYPAD V01 PCB

KEYPAD V01 is an open source STM32 PCB design by jmos1, published on GitHub. It is a 2-layer board measuring 109 × 57.2 mm, with 42 components from 20 distinct parts.

Its main chip is the STM32F103C8T6TR, from the STM32 family. Other key parts include the PUSB3FR4Z and TL1963A-33DCQT. By type, the board carries 13 capacitors, 11 resistors, 9 switches, 3 ICs, 2 connectors and 1 transistor.

From the project

The BOM, schematic PDF, and gerber files are all accessible in the 'Outputs/' folder. Other project files are not included because they add clutter and can be generated from the project itself in KiCad. Thanks.

KEYPAD V01: common questions

What microcontroller does the KEYPAD V01 use?

The KEYPAD V01 is built around the STM32F103C8T6TR, from the STM32 family.

How big is the KEYPAD V01 PCB?

The KEYPAD V01 measures 109 × 57.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the KEYPAD V01?

42 components, from 20 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the KEYPAD V01 design files?

From the jmos1/KEYPAD_V01 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the KEYPAD V01 design in my own project?

The repository has no license, so all rights stay with jmos1. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the KEYPAD V01 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.
