CadSoft Eagle library with Arduino Nano, 2.2″ QVGA TFT LCD

There is CadSoft EAGLE library from Element 14 with Arduino parts. Don’t know why, but I didn’t succeed EAGLE to auto route the trace / nets connected to Arduino Nano package. So I decided to make my own version. The library includes:

  • Arduino Nano R3
  • CD4050 (HFE4050) Non-inverting buffer / logic level converter
  • HKE HRS1H-S miniature SPST relay
  • 2.2″ QVGA TFT QVGA Color LCD + SDcard module
parts1 2.2 TFT LCD SDcard
There are several version of this 2.2″ TFT LCD module, popular within Arduino community. It features 240*340 pixels resolution, SPI interface for both LCD and SDCard.The module included in this library has a 5 pins on SDcard interface side: 4 pins for SDCard and 1 pin F_CS for CHIP SELECTing W25Q64 SPI flash memory, but as seen in photo, the flash chip is not soldered (U3 place). The module has 3.3V logic level and the display driver is ILI9341 comptible. Schematic and PCB drawing are included in docs folder.

Download the EAGLE library on GitHub.
