Design the interface on our display by using online tool in few minutes




  • Automatically detect ST7920(Parellel mode only), KS0108 and ST7565 (SPI), no config needed
  • Also support ST7565 Parallel mode by using "SLCD3" command following with 8 bytes init parameters
  • Power Supply: 4.85V to 5.5V (for 5V LCD display) or 3.3V to 7.5V (for 3.3V LCD display)
  • Power consumption of adapter:2mA @ 5.0V
  • Communication mode: UART/I2C/SPI, detect your setting automatically
  • Receiving buffer: 256 bytes
  • Work with all microcontroller and microprocessor
  • Communication signal can work on 3.3V and 5.0V TTL
  • Default setting: UART baud 9600bps, I2C 0x27 address
  • UART baud (bps): 300, 1200, 2400, 4800, 9600, 14400, 19200, 28800, 38400, 57600, 115200, 203400, 406800.

  • Product size: (WxHxD):52x34x3.1mm (2.0X1.35x0.12")
  • Simple command sets, easy to remember
  • Graphics engine integrated, draw Line, Circle, Rectangle, can set pattern for Line (Dot, Dash...)
  • 7 preloaded fonts, font’s data structure full compatible with U8Glib
  • 4 uploadable user fonts, can display any characters and graph very simple
  • Draw characters or graph in 4 direction
  • Back light can be adjusted by software
  • 3 individual out put pins with High current sink/source 25 mA/25 mA, can drive LED/relay and more
  • ~900 bytes eeprom for data, 16K bytes flash for splash screen and user font

Connect with your master circuit:

  Because the ST7565 chip used widely in 12864 LCD panels, and it’s very flexible of configuration, you need set at least 8 bytes of init parameters, if the ST7565 (SPI) not working well with this adapter, please use command “SLCD2” following by 8 bytes of init parameters also:
