Motion play main: common questions
What microcontroller does the Motion play main use?
The Motion play main is built around the ESP32-S3-WROOM-1-N16R8, from the ESP32 family.
How big is the Motion play main PCB?
The Motion play main measures 88.2 × 38.5 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Motion play main?
84 components, from 54 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Motion play main design files?
From the moclei/motion-play repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Motion play main design in my own project?
The repository has no license, so all rights stay with moclei. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Motion play main without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
