BusinessCard: common questions
What microcontroller does the BusinessCard use?
The BusinessCard is built around the STM32F103C8Tx, from the STM32 family.
How big is the BusinessCard PCB?
The BusinessCard measures 100 × 50 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the BusinessCard?
118 components, from 14 distinct parts. The full bill of materials is listed on this page.
Where can I download the BusinessCard design files?
From the anna328p/BusinessCard repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the BusinessCard design in my own project?
Yes, under the terms of its TAPR-OHL-1.0 license, which anna328p chose for the repository.
Can I test firmware for the BusinessCard 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.
