Uno
About the Uno PCB
Uno is an open source STM32 PCB design by lukasloetkolben, published on GitHub under the MIT license. It is a 2-layer board measuring 103.2 × 74.1 mm, with 131 components from 59 distinct parts.
Its main chip is the STM32F413RGTx, from the STM32 family. Other key parts include the FSUSB42UMX, TJA1042TK_3_1J, SY8368AQQC, TPS92511DDAR and TS-1087S-01526. By type, the board carries 48 capacitors, 37 resistors, 12 ICs, 9 diodes, 7 transistors and 4 inductors.
From the project
Note: the Uno pcb has been tested and is working. Many thanks to D. Fyffe for sending me his UNO board for reverse engineering!

Uno: common questions
What microcontroller does the Uno use?
The Uno is built around the STM32F413RGTx, from the STM32 family.
How big is the Uno PCB?
The Uno measures 103.2 × 74.1 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Uno?
131 components, from 59 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 Uno design files?
From the lukasloetkolben/OpenpilotHardware 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 Uno design in my own project?
Yes, under the terms of its MIT license, which lukasloetkolben chose for the repository.
Can I test firmware for the Uno 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.
