About the RP235X-B-Evaluator PCB

RP235X-B-Evaluator is an open source Raspberry Pi PCB design by Oak-Development-Technologies, published on GitHub under the CERN-OHL-P-2.0 license. It is a 4-layer board measuring 50 × 50 mm, with 61 components from 29 distinct parts.

Its main chip is the RP235X-B, from the Raspberry Pi family. Other key parts include the TLV75533PDBV, DF40C-30DP-0.4V51 and W25Q128JWPIM. By type, the board carries 25 capacitors, 16 resistors, 6 ICs, 5 connectors, 3 switches and 3 diodes.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

Open source repository for storing the files for the RP235X-B Evaluator, an RP235X-B Evaluation board.

Mind the name of the files, there is plans to eventually add an FPGA add on board for this. Stay tuned! :)

RP235X-B-Evaluator: common questions

What microcontroller does the RP235X-B-Evaluator use?

The RP235X-B-Evaluator is built around the RP235X-B, from the Raspberry Pi family.

How big is the RP235X-B-Evaluator PCB?

The RP235X-B-Evaluator measures 50 × 50 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the RP235X-B-Evaluator?

61 components, from 29 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 RP235X-B-Evaluator design files?

From the Oak-Development-Technologies/RP235X-B-Evaluator 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 RP235X-B-Evaluator design in my own project?

Yes, under the terms of its CERN-OHL-P-2.0 license, which Oak-Development-Technologies chose for the repository.

Can I test firmware for the RP235X-B-Evaluator without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
