If there’s one thing we like at Tom’s Hardware, it’s Raspberry Pi-powered stream decks. We even have a tutorial on how to make a Pico-powered stream deck keypad but today’s project by Blue Hippo takes things a step further.
This Pico-powered stream deck doesn’t just interface with user input, it has four programmable displays so you know exactly what feature each button corresponds with. Underneath each of the displays is a push button. Pressing on the screen pushes the button and performs an action, acting as a USB HID device.

The best Raspberry Pi projects are ones you can recreate at home and, to our delight, Blue Hippo has made a list of everything you need to get started. Everything is powered by a Raspberry Pico and built on top of a prototype PCB.
He was able to squeeze four SSD1306 OLED screens into the design, each with a resolution of 128 x 32px and programmable buttons. A 74HC4051 8-channel analog multiplexer was also used to help manage the modules.
Blue Hippo opted to use CircuitPython to program the stream deck along with a few Adafruit libraries to interface with all of the modules. When assembled, the system can be connected to a PC via USB which will recognize button presses from the SSD1306 as key presses. This input can be programmed to control applications like OBS.
