About the Mass Spring Damper SysID Lab PCB

Mass Spring Damper SysID Lab is an open source RP2040/RP2350 PCB design by Scalable-Open-Source-Labs, published on GitHub under the MIT license. It is a 2-layer board measuring 185 × 83 mm, with 82 components from 26 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the LM393, LM358, GS3011C, MAX7219 and ITR8307-S17-TR8. By type, the board carries 32 resistors, 27 capacitors, 16 ICs, 3 switches, 1 crystal and 1 connector.

From the project

An open source Mass-Spring-Damper to assist with teaching System Identification

Datasheet/ Each schematic symbol's Datasheet field links to it with a path relative to its own project folder (e.g. ../Datasheet/SMTSO.pdf), so this directory should only ever contain files that a .kicadsch` actually references. Call up a datasheet from within the schematic editor by hovering over a symbol and pressing the 'D' key.

Datasheets for parts that aren't placed as KiCad components (hand-assembly hardware sourced in Ordering-Instructions.md, like the carriage-capture bolt) belong in the root Datasheets/ directory instead, not here.

Mass Spring Damper SysID Lab: common questions

What microcontroller does the Mass Spring Damper SysID Lab use?

The Mass Spring Damper SysID Lab is built around the RP2040, from the RP2040/RP2350 family.

How big is the Mass Spring Damper SysID Lab PCB?

The Mass Spring Damper SysID Lab measures 185 × 83 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mass Spring Damper SysID Lab?

82 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mass Spring Damper SysID Lab design files?
