Oscilloscope based on the Raspberry Pi Pico

Open-Source Oscilloscope based on the Raspberry Pi Pico

The minimum viable product is ready, and development of new features is ongoing. Updates will be published regularly, although the pace may be slow.

Flexible Data Acquisition: Use either the internal ADC(s) of the Raspberry Pi Pico to measure up to ~2MSa/s or 1-2 faster external ADCs (requires a custom PCB) for >50MSa/s at 8 bit. Optional PCB: The project can be built on a breadboard or with an optional PCB for easier assembly and improved performance. Display Options**: Supports both SSD1306 and ST7789 displays, with potential support…

PicoDSO: common questions

What microcontroller does the PicoDSO use?

The PicoDSO is built around the Pico, from the RP2040/RP2350 family.

How big is the PicoDSO PCB?

The PicoDSO measures 50.9 × 104.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PicoDSO?

65 components, from 36 distinct parts. The full bill of materials is listed on this page.

Where can I download the PicoDSO design files?

From the HL65536/picoDSO repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the PicoDSO design in my own project?

Yes, under the terms of its AGPL-3.0 license, which HL65536 chose for the repository.

Can I test firmware for the PicoDSO 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.
