Odd Inputs And Peculiar Peripherals: A MacroPad With A Handy Layout Screen

The idea of a macro keypad is a great one, a set of keys programmable with frequent but complex tasks. But once programmed, how can the user keep track of which key does what? To save the world from grubby, hand-written sticky labels, here’s [Andreas Känner] with the Badger 2040 keypad — a macro pad with a display to show keymap info that’s fully programmable using CircuitPython.

At its heart is a Pimoroni Badger 2040 e-ink screen and RP2040 board which sits in a 3D-printed enclosure which in turn magnetically attaches to a 3D-printed keyboard enclosure. Inside is an I/O expander board, which is hand-wired to the switches. The firmware allows for easy configuration and even extension of the keypad itself, and presents itself to the host computer through USB. It’s even possible to have multiple different layouts on the same device.

Full details can be found in a comprehensive write-up on his website, and all the files are in a GitHub repository. If this doesn’t satisfy your need for customisable input goodness, then it’s not the first macro keypad we’ve shown you.
