About the Bleepie-HW PCB

Bleepie-HW is an open source RP2040/RP2350 PCB design by sammachin, published on GitHub under the CERN-OHL-P-2.0 license. It is a 2-layer board measuring 46.8 × 37 mm, with 3 components from 3 distinct parts.

Its main chip is the RP2040-Tiny, from the RP2040/RP2350 family.

It belongs with the rf & radio designs in this gallery.

From the project

Hardware Design for the Bleepie Hexpansion

A Tildagon hexpansion PCB built around a Waveshare RP2040-Tiny module, an Ra-02 (SX127x) LoRa radio and a PS1240 piezo buzzer. It plugs into the hexpansion edge connector on the EMF Camp Tildagon badge.

Designed in KiCad. Board and design files are released under the CERN Open Hardware Licence v2 — Permissive.

The Ra-02 is best sourced as a genuine Ai-Thinker module. Availble from DigiKey UK There are clones on the usual sites (aliExpress etc) and these do work, but the frequency calibration is often even further out.

Bleepie-HW: common questions

What microcontroller does the Bleepie-HW use?

The Bleepie-HW is built around the RP2040-Tiny, from the RP2040/RP2350 family.

How big is the Bleepie-HW PCB?

The Bleepie-HW measures 46.8 × 37 mm, has 2 copper layers and is 1 mm thick.

How many components are on the Bleepie-HW?

3 components, from 3 distinct parts. The full bill of materials is listed on this page.

Where can I download the Bleepie-HW design files?

From the sammachin/Bleepie-HW repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Bleepie-HW design in my own project?

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

Can I test firmware for the Bleepie-HW 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.
