Tafiti Onboard Comms: common questions

What microcontroller does the Tafiti Onboard Comms use?

The Tafiti Onboard Comms is built around the STM32H743VIT6, from the STM32 family.

How big is the Tafiti Onboard Comms PCB?

The Tafiti Onboard Comms measures 90.2 × 96 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Tafiti Onboard Comms?

44 components, from 24 distinct parts. The full bill of materials is listed on this page.

Where can I download the Tafiti Onboard Comms design files?

From the tafiti-org/Subsytems repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Tafiti Onboard Comms design in my own project?

Yes, under the terms of its MIT license, which tafiti-org chose for the repository.

Can I test firmware for the Tafiti Onboard Comms 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.
