Melodica mainboard: common questions
What microcontroller does the Melodica mainboard use?
The Melodica mainboard is built around the STM32L031K6Tx, from the STM32 family.
How big is the Melodica mainboard PCB?
The Melodica mainboard measures 29.5 × 84.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Melodica mainboard?
11 components, from 6 distinct parts. The full bill of materials is listed on this page.
Where can I download the Melodica mainboard design files?
From the connormichalec/395-Melodica repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Melodica mainboard design in my own project?
The repository has no license, so all rights stay with connormichalec. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Melodica mainboard 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.
