About the SINSONTE MODEL B PCB

SINSONTE MODEL B is an open source RP2040/RP2350 PCB design by galopago, published on GitHub under the MIT license. It is a 2-layer board measuring 90 × 41 mm, with 34 components from 22 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. By type, the board carries 18 connectors, 7 resistors, 3 capacitors, 2 transistors, 1 IC and 1 battery holder.

From the project

Sound player board based on Raspberry Pi Pico

Sound player based on Raspberry Rpi Pico. Sound data are stored in onboard memory. Very few external (easy to find & solder) components required. The project was designed to be in sleep mode for a very long time powered by batteries. Can be used for musical wall clocks, talking dolls, toys, etc.

Printed circuit board with all components soldered.

SINSONTE MODEL B: common questions

What microcontroller does the SINSONTE MODEL B use?

The SINSONTE MODEL B is built around the Pico, from the RP2040/RP2350 family.

How big is the SINSONTE MODEL B PCB?

The SINSONTE MODEL B measures 90 × 41 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the SINSONTE MODEL B?

34 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the SINSONTE MODEL B design files?

From the galopago/sinsonte repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the SINSONTE MODEL B design in my own project?

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

Can I test firmware for the SINSONTE MODEL B 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.
