TPP: common questions

What microcontroller does the TPP use?

The TPP is built around the STM32F405RGTx, from the STM32 family.

How big is the TPP PCB?

The TPP measures 96 × 90 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the TPP?

211 components, from 51 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 TPP design files?

From the juan-LARRAYA/TPP 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 TPP design in my own project?

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

Can I test firmware for the TPP 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.
