The Poly Keyboard uses tiny OLED displays as keys (DIY, work in progress)


The Poly Keyboard is a Do-it-yourself job to develop a keyboard with very small OLED shows beneath each crucial, letting you to switch languages, layouts, or other functions by means of computer software.

It is been underneath growth for a several yrs, but this month the creator of the undertaking assembled the first practical prototype of the keyboard… or at least of the remaining facet of what will at some point be a break up keyboard.

A shorter demo online video shows the key labels switching when a person presses the Caps Lock key. But theoretically this kind of screens-as-labels style would also allow for you to improve languages, switch to a Dvorak format or a distinct arrangement of keys, or spotlight just the keys you require for a activity, movie modifying application, or other software package.

It’s not the first time we’ve found a keyboard-with-screen-as-keys style and design, but Poly is definitely a single of the far more intriguing entries in this place. It’s an open components layout: the PCB structure, 3D printer documents for keycaps, and other documents are readily available at GitHub. And the firmware is primarily based on the open up resource QMK keyboard firmware.

When the challenge was originally made to use an STM32F407 microcontroller, price ranges went up throughout the pandemic and ensuing supply chain scarcity, so the Poly Keyboard now is now run by a Raspberry Pi RP2040 microcontroller.

Under each of the keys is a .42 inch black and white mini OLED display screen with a resolution of 72 x 40 pixels.

You can obtain additional facts about the task by subsequent the developer’s development on Twitter or in a collection of ports on a Ko-fi site.
