Product description: AdafruitST7735R - TFT LCD 1.44'' 128x128px display with microSD reader
1.44" TFT LCD graphic display with 128 x 128 px resolution and 18-bit colour depth. It works with 3.3V and 5V, communicates via SPI bus. Additionally, the board has a micro SD memory card reader.
The screen is based on the ST7735R controller with built-in video buffer.It communicateswith a main microcontroller via SPI bus. Thanks to the voltage converter the system works with both 3.3 V and 5 V logic. The installed slot allows to provide graphic files on themicro SDcardwithFAT16/FAT32 system.
The set includesgoldpin connectors(for self-soldering), which will allow toThe display is connected to thecontact plateor connected bywires.
