About the HALO-0 PCB

HALO-0 is an open source RP2040/RP2350 PCB design by Cocotrilito, published on GitHub under the MIT license. It is a 2-layer board measuring 21 × 51 mm, with 35 components from 18 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the MCP1700x-330xxTT and W25Q128JVS. By type, the board carries 17 capacitors, 8 resistors, 4 connectors, 3 ICs, 1 crystal and 1 switch.

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

HALO-0: common questions

What microcontroller does the HALO-0 use?

The HALO-0 is built around the RP2040, from the RP2040/RP2350 family.

How big is the HALO-0 PCB?

The HALO-0 measures 21 × 51 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the HALO-0?

35 components, from 18 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 HALO-0 design files?

From the Cocotrilito/HALO-0 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 HALO-0 design in my own project?

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

Can I test firmware for the HALO-0 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.
