STEMMA SUNDAY – A mini PiTFT display with STEMMA QT connector @adafruit @raspberry_pi @sparkfun @seeedstudio @dfrobotcn #qwiic #grove #gravity #stemma #stemmaQT
As displays have gotten smaller and higher res, we’ve seen some really cute mini TFTs. this one is only 1.1″ but has 240×135 pixels, great for a little display. we wrote a kernel driver for it, and with the STEMMA QT connector on the bottom, its ez to connect sensors like this MSA301. Then run python scripts to print out the motion output. Fun! (video).
WHAT IS STEMMA? STEMMA is not an original idea, we’re working within an ecosystem of many other plug and play systems. We started STEMMA in 2014, and intended to be compatible with Grove only (cause that’s all that existed at the time) but then when Qwiic came around in 2017, added a smaller connector so we could work with those parts too!
STEMMA attempts to be as cross-compatible as possible with both Grove and Gravity (compatible connectors & 3-5V power/logic). STEMMA QT is cross-compatible with Qwiic - STEMMA QT connector/cable is same as Qwiic. You can use STEMMA QT devices with Qwiic devices/controllers.
