how to connect Stemma QT to E-ink display

Post by jehan60188 »

I have this ESP32 board: https://www.adafruit.com/product/5325

Was wondering if its possible to connect to one of these e-ink displays: https://www.adafruit.com/product/3933 or https://www.adafruit.com/product/4778

What's the best way to do it? Or is it too much trouble? Should I look in to alternative hardware?

thanks!

You can connect an eink breakout (e.g. https://www.adafruit.com/product/4868, https://www.adafruit.com/product/4196, https://www.adafruit.com/product/4098) using the QtPy's SPI bus. But not I2C, so not the STEMMA-QT interface. I advise using an eink breakout rather than a HAT/Bonnet or FeatherWing.

cool, thanks!

So I can take the ESP32, and solder it to either this https://www.adafruit.com/product/4098, or https://www.adafruit.com/product/1028 right?

Yes, using the SPI connection. See the associated guides for details.
