MidiLedController hw: common questions
What microcontroller does the MidiLedController hw use?
The MidiLedController hw is built around the STM32F051K8Tx, from the STM32 family.
How big is the MidiLedController hw PCB?
The MidiLedController hw measures 99.8 × 100.1 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the MidiLedController hw?
138 components, from 43 distinct parts. The full bill of materials is listed on this page.
Where can I download the MidiLedController hw design files?
From the cracked-machine/MidiLedController_hw repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the MidiLedController hw design in my own project?
The repository has no license, so all rights stay with cracked-machine. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the MidiLedController hw 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.
