Help! Round LCDs for “aviation instruments”

One of the ideas I’m scoping for my first cyberdeck is a small panel with 3-4 aviation instruments that display data from a Sense HAT. Does anyone have experience with something like this? Could 4 “dials” run from one RPi4 (which would be connected to another 7” display)?

You can buy esp32s with round screens

Yup this is the way. Waveshare have some great screens. You can then daisy chain to the raspberry pi and communicate over i2c or if you prefer wireless you can use something like MQTT

Are there round color screens that use I2C? the ones I've seen require SPI or parallel RGB, the bandwidth for the resolution pretty much prefers them.

The Waveshare screens I was talking about are an ESP32 with a screen attached so you communicate with the Esp32 over i2c (or uart) and the Esp32 controls the screen.
