Module Features

• 1. No backlight, keeps displaying last content for a long time even when power down, and the time can be up to half a year
• 2. Ultra low power consumption, basically power is only required for refreshing
• 3. SPI control interface, which can be connected to Raspberry/Arduino/rduino/STM32 and other main control boards
• 4. Provide complete supporting information (Arduino sample program, showing global display and partial display)

• DIN: SPI communication MOSI pin, 4-wire or 3-wire SPI mode can be selected by switch
• CLK: SPI communication SCK pin
• CS: SPI chip select pin (active low)
• DC: data/command control pin (high level means data, low level means command)
• RST: External reset pin (low level reset)
• BUSY: working status output pin (high level means working) 

Module parameters

• Size: 2.13 inch
• Dimensions (bare screen): 59.2mm x 29.2mm x 1.05mm
• Dimensions (module): 65mmx30.2mm
• Display size (viewable area): 48.55mm × 23.71mm.

• Resolution: 212*104 
• Display color: black and white two colors / black and white red three colors / black and white yellow three colors.
• Gray level: 2
• Partial refresh: 0.3s (only black and white dual colors support partial refresh)
• Global refresh: 2s (black and white two colors) / 15s (black and white red three colors) / 15s (black and white yellow three colors)
• Standby power consumption: <=0.017mW
• [Remarks]: Refresh time: The refresh time is experimental test data, the actual refresh time will have an error, and the actual effect shall prevail. There will be a flickering effect during the global refresh process, this is normal
• Power consumption: The power consumption data is the experimental test data. The actual power consumption will have certain errors due to the existence of the driver board and the actual usage. The actual results shall prevail.
