TOAD: common questions

What microcontroller does the TOAD use?

The TOAD is built around the STM32F405RxTx, from the STM32 family.

How big is the TOAD PCB?

The TOAD measures 70 × 75 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the TOAD?

152 components, from 56 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 TOAD design files?

From the cuspaceflight/m3-avionics repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the TOAD design in my own project?

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

Can I test firmware for the TOAD 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.
