About the Raccoon PCB

Raccoon is an open source STM32 PCB design by sunnyhaibin, published on GitHub under the MIT license. It is a 4-layer board measuring 100.9 × 71.5 mm, with 56 components from 31 distinct parts.

Its main chip is the STM32F413RGT6, from the STM32 family. Other key parts include the SIP32431DR3, AMS1117-5.0, AMS1117-3.3, TJA1042T-3 and NEO-M8P. By type, the board carries 19 capacitors, 10 ICs, 10 resistors, 5 connectors, 5 diodes and 2 switches.

It belongs with the rf & radio and usb & debug tools designs in this gallery.

From the project

PCB and firmware for a USB to CAN interface, with support for 4 CAN transceivers and an optional NEO-MP8 GNSS module. The design is a reverse-engineering of comma.ai's Black Panda. It uses a modified version of the panda firmware/SDK.

The design uses an automotive-grade Deutsch header, which eliminates the need for a switching relay. Feel free to replace this with something else. If you want to use "ODB-C" you'll need to use pins C0/C3 (inputs), C10/C11 (outputs).

To use the deutsch header, you'll need a crimper and some parts:

- 1 DTM13-12A or some variant of the header. This needs hand-soldered. - 1 DTM06-12S, the male connector - 1 WM-12S, a wedgelock - 12 Crimpable Sockets

Raccoon: common questions

What microcontroller does the Raccoon use?

The Raccoon is built around the STM32F413RGT6, from the STM32 family.

How big is the Raccoon PCB?

The Raccoon measures 100.9 × 71.5 mm, has 4 copper layers and is 4.69 mm thick.

How many components are on the Raccoon?

56 components, from 31 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 Raccoon design files?

From the sunnyhaibin/raccoon 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 Raccoon design in my own project?

Yes, under the terms of its MIT license, which sunnyhaibin chose for the repository.

Can I test firmware for the Raccoon 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.
