Panel: common questions
What microcontroller does the Panel use?
The Panel is built around the STM32F103C8Tx, from the STM32 family.
How big is the Panel PCB?
The Panel measures 99.7 × 108 mm and is 1.6 mm thick.
How many components are on the Panel?
94 components, from 43 distinct parts. The full bill of materials is listed on this page.
Where can I download the Panel design files?
From the embeddedalpha/PCB-Design repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Panel design in my own project?
Yes, under the terms of its MIT license, which embeddedalpha chose for the repository.
Can I test firmware for the Panel 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.
