From the project
Hardware project for open source wheel chair recline control electronics
The Recline control system allows the wheel chair user to adjust the recline position of their chair at their leisrure. Its a complete electrical controls system with with safety in mind. The system is split across two piece of electrical hardware design as two separated printed circuit boards. The First board functions as the controller and human machine interface, the second board functions as an intelligent controller for the actuators, solenoids, and air compressor related to controlling the chair recline postion and the chair's pneumatic suspension.The human machine interface board is…

Recline actuator controller: common questions
What microcontroller does the Recline actuator controller use?
The Recline actuator controller is built around the RP2040, from the RP2040/RP2350 family.
How big is the Recline actuator controller PCB?
The Recline actuator controller measures 140 × 100 mm, has 4 copper layers and is 1.567 mm thick.
How many components are on the Recline actuator controller?
181 components, from 50 distinct parts. The full bill of materials is listed on this page.
Where can I download the Recline actuator controller design files?
From the Accessibilita/recline-controls repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Recline actuator controller design in my own project?
Yes, under the terms of its CERN-OHL-S-2.0 license, which Accessibilita chose for the repository.
Can I test firmware for the Recline actuator controller 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.
