TSUMO BOT hardware: common questions

What microcontroller does the TSUMO BOT hardware use?

The TSUMO BOT hardware is built around the STM32L476RGT6, from the STM32 family.

How big is the TSUMO BOT hardware PCB?

The TSUMO BOT hardware measures 97.7 × 58.5 mm, has 4 copper layers and is 1.5842 mm thick.

How many components are on the TSUMO BOT hardware?

93 components, from 43 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 TSUMO BOT hardware design files?

From the troyodia/TSUMO_BOT_hardware 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 TSUMO BOT hardware design in my own project?

The repository has no license, so all rights stay with troyodia. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the TSUMO BOT hardware 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.
