About the PCBussinesCard PCB
PCBussinesCard is an open source STM32 PCB design by vekkax, published on GitHub. It is a 2-layer board measuring 85 × 55 mm, with 19 components from 13 distinct parts.
Its main chip is the STM32L452CEUx, from the STM32 family. Other key parts include the NT2H1311F0DTL. By type, the board carries 9 capacitors, 3 ICs, 3 connectors, 2 diodes, 1 switch and 1 resistor.
From the project
PCB bussiness card, automatically loads a file when plugin to usb
The PCB Business Card is a hardware project inspired by the Hackaday 2024 Business Card Contest and the business cards created by Salvaged Circuitry.
It is a compact and creative way to showcase your capabilities as a hardware designer while sharing your contact details. Beyond being a novelty, the card also functions as a (slightly impractical, but fun) development platform.

PCBussinesCard: common questions
What microcontroller does the PCBussinesCard use?
The PCBussinesCard is built around the STM32L452CEUx, from the STM32 family.
How big is the PCBussinesCard PCB?
The PCBussinesCard measures 85 × 55 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the PCBussinesCard?
19 components, from 13 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 PCBussinesCard design files?
From the vekkax/PCBussinessCard repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the PCBussinesCard design in my own project?
The repository has no license, so all rights stay with vekkax. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the PCBussinesCard 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.
