e-Paper IoT Driver HAT for Raspberry Pi, Supports NB-IoT/eMTC/GPRS
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.
Features
- 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)
- Onboard voltage translator, select 3.3V/5V operating voltage by switch
- Provides Windows host code (based on Alibaba Cloud), make it easy to study/develop, or integrate it into IoT applications
- Comes with development resources and manual (examples for Raspberry Pi/STM32)
