Tmb board: common questions
What microcontroller does the Tmb board use?
The Tmb board is built around the STM32F407VGTx, from the STM32 family.
How big is the Tmb board?
The Tmb board measures 99.1 × 95.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Tmb board?
160 components, from 59 distinct parts. The full bill of materials is listed on this page.
Where can I download the Tmb board design files?
From the janfietz/tmb_board repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Tmb board design in my own project?
Yes, under the terms of its CC-BY-SA-4.0 license, which janfietz chose for the repository.
Can I test firmware for the Tmb board 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.
