MasterModule: common questions
What microcontroller does the MasterModule use?
The MasterModule is built around the YAAJ_BluePill, from the STM32 family.
How big is the MasterModule PCB?
The MasterModule measures 50 × 70 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the MasterModule?
22 components, from 17 distinct parts. The full bill of materials is listed on this page.
Where can I download the MasterModule design files?
From the dmitry131131/PumpSystem repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the MasterModule design in my own project?
The repository has no license, so all rights stay with dmitry131131. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the MasterModule 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.
