How to find a Chimei LCD display : 3.5" TFT LCD Display RGB LCD Kit Monitor 320x240


Today there are a lot of small screens available on eBay or Aliepress. The most common are dedicated to the RaspberryPi and have an HDMI input. This is not what we need for Telewizor!

For Telewizor we need a Led screen with two AV inputs. Its size is 3.5 inch and its ratio is 4: 3 just like an old TV. Pixels are 320x240 px, do not order larger or smaller.

Luckily, it is this type of AV screen that equip cars with a back camera. The technology is still analog. And it is this type of composite signal that our Arduino Nano will generate.
