The Forest Hub enables a user to connect an analog joystick and up to four assistive switches to emulate a USB Mouse or USB Gamepad. As a USB Mouse, the joystick controls cursor movement and the assistive switches activate the left mouse button, right mouse button, middle mouse button, and scroll. As a USB Mouse, the joystick maps to the joystick/thumbstick and the assistive switches map to the joystick buttons. An additional assistive switch can be attached to the Hub to cycle between three setting slots and change the output mode between USB Mouse mode and USB Gamepad mode.
The device is comprised of a custom printed circuit board, off-the-shelf electronics, and 3D printed parts. The overall cost of materials for a single build is about $100. The individual unit cost cost is closer to $55.
The Forest Hub is open assistive technology (OpenAT). Under the terms of the open source licenses, the device may be built, used, and improved upon by anyone.
Last updated: 2024-Apr-17 The latest version (V2.1) includes a new easier to use LED jig, updated firmware with center calibration, and updated documentation. An updated version of the PCB and enclosure has been released (V2.0.1, 2024-Feb-20). The last version of the Forest Hub (v2.0.1) has been built and tested.

This design is part of the OpenAT Joystick Project, a collection of open source designs for digital access and adapted gaming.
This is an open-source assistive technology, so anyone is free to build it. All of the files and instructions required to build the device are contained within this repository. Refer to the Maker Guide below.
If you would like to obtain a Forest Hub, you may submit a build request through the MMC Assistive Device Library Listing to have a volunteer maker build the device. As the requestor, you are responsible for reimbursing the maker for the cost of materials and any shipping.
If you have the skills and equipment to build this device, and would like to donate your time to create the switch for someone who needs it, visit the MMC Maker Wanted section.
The Maker Guide contains all the necessary information to build the device.
Use the Maker Checklist in the Maker Guide to confirm details and customization options with the user.
The manufacturing files for the PCB are located in the PCB_Build_Files folder.
The Bill of Materials lists all of the parts and 3D printed components required to build the device.
The print files can be found in the /Build_Files/3D_Printing_Files folder.
Reference the Assembly Guide section in the Maker Guide for the tools and steps required to build the device.
