This project uses the Adafruit Feather nRF52840 Express board to create a Bluetooth switch interface to allow users with disabilities the functionality of a wireless connection to their computer or mobile device using their current wired switches. The interface may be Bluetooth connected to a computer or iOS device and runs off the LiPo battery. The battery is charged when a USB cable is connected to the board.
This project is geared towards a novice user using Circuitpython which supports drag and drop functionality for the needed code and library files.
The case design is a remix using the Ruiz’s brothers case for the Emoji Keyboard project. The STL and Fusion360 files are available through Thingiverse as well.
