About the PCB2 PCB

PCB2 is an open source RP2040/RP2350 PCB design by Hasona57, published on GitHub. It is a 2-layer board measuring 69.5 × 46.5 mm, with 12 components from 6 distinct parts.

Its main chip is the XIAO-RP2040-DIP, from the RP2040/RP2350 family. Other key parts include the DM-OLED096-636, MAX30100EFD_ and XC6206P182MR. By type, the board carries 6 capacitors, 4 ICs and 2 resistors.

It belongs with the wearables and sensors designs in this gallery.

From the project

Sensor project on PCB

This project is a compact PCB design that integrates the MAX30100 sensor to measure heart rate and blood oxygen (SpO₂) levels. The PCB is intended to be used in a wearable watch, offering real-time health monitoring.

Designed using KiCad and programmed with Arduino IDE, this project is ideal for health-tracking applications, DIY fitness wearables, and biomedical prototypes.

PCB2: common questions

What microcontroller does the PCB2 use?

The PCB2 is built around the XIAO-RP2040-DIP, from the RP2040/RP2350 family.

How big is the PCB2 PCB?

The PCB2 measures 69.5 × 46.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the PCB2?

12 components, from 6 distinct parts. The full bill of materials is listed on this page.

Where can I download the PCB2 design files?

From the Hasona57/PCB2 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the PCB2 design in my own project?

The repository has no license, so all rights stay with Hasona57. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the PCB2 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.
