XCS-03A-MAIN: common questions
What microcontroller does the XCS-03A-MAIN use?
The XCS-03A-MAIN is built around the MM32F0163D7P, from the STM32 family.
How big is the XCS-03A-MAIN PCB?
The XCS-03A-MAIN measures 153.6 × 50 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the XCS-03A-MAIN?
242 components, from 79 distinct parts. The full bill of materials is listed on this page.
Where can I download the XCS-03A-MAIN design files?
From the hedong2023/ovobot repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the XCS-03A-MAIN design in my own project?
The repository has no license, so all rights stay with hedong2023. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the XCS-03A-MAIN 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.
