About the Tspico hardware PCB

Tspico hardware is an open source RP2040/RP2350 PCB design by factus10, published on GitHub under the CERN-OHL-S-2.0 license. It is a 4-layer board measuring 130 × 64.3 mm, with 144 components from 43 distinct parts.

Its main chip is the RP2350B, from the RP2040/RP2350 family. Other key parts include the 74LVC245APW,118, 74LVC32APW,118, EM74LVC06AD, XL9555 and GD25Q128ESIGR. By type, the board carries 63 resistors, 52 capacitors, 15 ICs, 5 connectors, 4 switches and 3 diodes.

Status 2026-10-19: prototype 3 (v3.0-proto3, changes below). Proto1 (v3.0-proto1) was built and brought up; proto2 added its fixes (below). Both proto2 and proto3 were routed by scripts/flow.py with no hand edits, DRC clean at every severity. ERC: one warning, U4's unused input tied to GND.

To order: the JLCPCB upload files (Gerber zip, BOM, placement), ordering notes, schematic PDF and renders are on the v3.0-proto3 release. L1, U22, J3 and J5 are fitted by hand. Proto2: v3.0-proto2.1 (L1 by hand) and v3.0-proto2 (L1 assembled by JLCPCB), same Gerbers. To regenerate them from this folder…

Tspico hardware: common questions

What microcontroller does the Tspico hardware use?

The Tspico hardware is built around the RP2350B, from the RP2040/RP2350 family.

How big is the Tspico hardware PCB?

The Tspico hardware measures 130 × 64.3 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Tspico hardware?

144 components, from 43 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 Tspico hardware design files?

From the factus10/tspico-hardware 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 Tspico hardware design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which factus10 chose for the repository.

Can I test firmware for the Tspico hardware without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.

Earlier revisions in the repo: tspico-v2.6, tspico-v2.5
