1. “LIGHT” connected to GND,
which are illuminated backlight.
2. A 3.3V controller is needed, otherwise
the display could be very vague.

1. RST – reset
2. CE – chip selection
3. DC – data/commands choice
4. DIN – serial data line
5. CLK – serial clock speed
6. 3.3V – VCC?
7. LIGHT – backlight control terminal
8. GND – power negative
84X84 dot matrix LCD can show 4 lines of
Use serial interface to communicate with
the master processor, the number of interface signal line greatly reduced, only
8 signal lines including power and GND; supports different types of MCU, such
as SPI, MCS51 serial mode of AVR. With transfer rate up to 4 Mbps, it can write
full speed display data without waiting.
Can use conductive glue to connect the
module to the circuit board, without connecting cable. The metal hook on the
module allows the module to stay on the circuit board firmly, and makes it very
easy to install and replace.
Low in power consumption, the operating
current in normal situation is lower than 200A
