Robotont electronics mainboard: common questions
What microcontroller does the Robotont electronics mainboard use?
The Robotont electronics mainboard is built around the STM32F407VGTX, from the STM32 family.
How big is the Robotont electronics mainboard PCB?
The Robotont electronics mainboard measures 304.3 × 274 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Robotont electronics mainboard?
407 components, from 92 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 Robotont electronics mainboard design files?
From the robotont/robotont-electronics-mainboard 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 Robotont electronics mainboard design in my own project?
The repository has no license, so all rights stay with robotont. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Robotont electronics 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.
