Other than importing gadgets, Adafruit sometimes also designs them. Today’s review is for their cool 1.3″ OLED display for the Raspberry Pi computer. It appears to fit exactly the top of the Raspberry Pi Zero WH (the one with the included header).
At $22.50, the hat is about twice the cost of the computer itself. The 128×64 display is enough for most projects, I’d guess.
I’m thinking that I’ll use this one to develop a cold wallet for cryptocurrency.
The hat (“bonnet”) includes a joystick with four positions and a pushbutton as well as two stand-alone pushbuttons on the right. It comes with good support on the Python side of things. If you’re like me and prefer Node JS, then you’ll be doing a lot of research on this one.
The interface is I2C. The device identifier is SSD1306. The example software includes text- and image-based Python and a bit of an animation of text.
In case you’re interested, I’ve written a tutorial for getting this setup.
