About the Sensor PCB

Sensor is an open source RP2040/RP2350 PCB design by Aidan-McNay, published on GitHub. It is a 2-layer board measuring 52 × 65 mm, with 19 components from 16 distinct parts.

Its main chip is the PicoW, from the RP2040/RP2350 family. Other key parts include the SN65HVD230DR, FDN340P, VEML6030-GS15 and DMG2305UX-7. By type, the board carries 7 resistors, 5 ICs, 3 connectors and 3 capacitors.

It belongs with the sensors designs in this gallery.

Sensor: common questions

What microcontroller does the Sensor use?

The Sensor is built around the PicoW, from the RP2040/RP2350 family.

How big is the Sensor PCB?

The Sensor measures 52 × 65 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Sensor?

19 components, from 16 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 Sensor design files?

From the Aidan-McNay/chimes-leds 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 Sensor design in my own project?

The repository has no license, so all rights stay with Aidan-McNay. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Sensor 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.
