This is a Raspberry Pi IoT driver board for e-Paper raw panels. It allows getting text/image data from IoT clouds through NB-IoT/eMTC/EDGE/GPRS network connection, and then display them on the e-Paper. Applications includes any scenario where remote refresh of display is required such as shelf display etc.

Package Includes

• e-Paper NB-IoT/GPRS HAT x1
• LTE full bands PCB antenna x1
• e-Paper Adapter x1
• 24PIN FFC x1
• 2×20PIN female pinheader x1
• RPi screws pack (2pcs) x1

Development Resources

Wiki Page  - http://www.waveshare.com/wiki/e-Paper_NB-IoT_GPRS_HAT

• Onboard SIM7000E module, controlled via UART, supports NB-IoT/eMTC/EDGE/GPRS communication
• e-Paper interface, controlled via SPI, compatible with various Waveshare SPI e-Paper raw panels
• Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
• Breakout SIM7000E and e-Paper control pins, for connecting with host control boards like STM32
• 3.7V lithium battery port and charging circuit, provides power to SIM7000E module or external 3.3V system (5V system like Raspberry Pi requires another power supply)
