Features ?My characteristics? No need for backlight, power off can maintain the last screen display content for a long time Very low power consumption, basically only consumes power during refresh Suitable for Raspberry Pi 2nd generation B/3th generation B/Zero/Zero W Reserve the SPI control interface pad for easy access to Arduino/Nucleo and other main control boards Provide complete supporting documentation (Raspberry/Arduino/STM32 and other sample programs) ?My parameters? Working voltage: 3.3V Communication interface: SPI Dimensions: 65mm × 30.2mm Display size: 23.71mm × 48.55mm Dot pitch: 0.194 × 0.194 Resolution: 250 × 122 Display color: black and white Gray level: 2 Refresh power consumption: 26.4mV(typ.)

VCC: 3.3V GND: GND NC: floating DIN: MOSI pin for SPI communication CLK: SPI communication SCK pin CS: SPI chip select pin (active low) DC: data/command control pin (high level indicates data, low level indicates command) RST: external reset pin (low level reset) BUSY: Busy output pin (low level means busy) Shipping list 2.13inch e-Paper HAT × 1 RPi Copper Pillar Pack (2PCS Set) ×1 2.54 horizontal patch header 9P ×1

No backlight, keeps displaying last content for a long time even when power down. Onboard voltage translator, compatible with 3.3V/5V MCUs,Comes with development resources and manual (examples compatible with Raspberry Pi/Arduino/STM32). Preserved solder pads for SPI interface, compatible with other controller boards like Arduino/Nucleo, etc. Ultra low power consumption, basically power is only required for refreshing.
