I'm trying to find an inexpensive 4" Mono Display like the image below to work on an Arduino Uno or ESP32. Hopefully, work in the temp range of -10F to 150F.
Can anybody point me in the right direction?
Thank you in advance,
Mike
Displays managing that low temperature will not be inexpensive. Money cab be spent on a heater for the display.
Google is Your best friend.
Do you remember Pythagoras from school maths lessons? 3² + 5² = 4² ?
If your measurements are correct you are looking for a display of around 5.8", or around 150mm, diagonal.
The image is a little blurry, but looks like a custom made LCD display, so you will not find one just like it. It also appears to be touch sensitive. Is that also a requirement?
I suspect you will have to look at a colour LCD in this size range. Bizarrely, they will almost certainly be cheaper than monochrome due to demand. If course, you don't have to use more than 2 colours!
Works with an ESP32: AmazonSmile: Waveshare 4.2inch E-Ink Display Module Communicating via SPI Interface 400x300 Resolution E-Paper with Embedded Controller for Raspberry Pi : Electronics
Use the GxEPD2 library. Expect a little learning curve on the library use.
Uno, most likely, does not have the ram to run the 4.2 inch e-ink display.
I have used a Matrix Orbital EVE2 display in an application that had to be outdoors in the middle of nowhere and needed to run at temperature extremes: desert in Arizona or in a Minnesota winter. The one I linked is rated to -20C. Whether they're "cheap" or not depends on your definition. I can say that they worked very well.
The nice thing about the EVE communication protocol is that the display stores all the image data and the CPU only sends it messages like "draw a line" etc so you don't need a lot of RAM on your CPU. MatrixOrbital has Arduino sample code.
