Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Remember that the ILI number has nothing to do with the circuit of the board - it's the  part number of the driver chip connected to the LCD panel. You can expect variations between manufacturers and even between different batches from the same manufacturer. If you want consistency then you have to order official part numbers from a proper stockist, not "2.4" ILI9488" from no-name Chinese sellers. :)

True, you get what you pay for. I don't think there's a 2.4" ili9488.

I was only giving an example. I don't really care if it exists or not. :)
