e-Paper IoT Driver HAT for Raspberry Pi, Supports NB-IoT/eMTC/GPRS

Description

E-Paper IoT Driver HAT For Raspberry Pi, Supports NB-IoT/EMTC/GPRS

Overview

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)

Specifications

• Communication interface: UART + SPI (4-wire SPI by default, switch to 3-wire SPI by soldering)
• Communication module: SIM7000E
  • Quad-Band LTE-FDD B3/B8/B20/B28
  • GPRS/EDGE 900/1800Mhz
  • GNSS (GPS, GLONASS, BeiDou, and Galileo, GNSS antenna is required and NOT included)
• Support SIM card: NB-IoT specific card, or 1.8V/3V normal SIM card
• Applicable region: China mainland, southeast Asia, Europe, Africa, Australia, etc. (for reference only, please check the supported bands according to your local service provider)
• Power supply voltage: 5V
• Logic level: 5V / 3.3V
• Applicable battery: 3.7V lithium battery via PH2.0 connector (NOT included)
• Dimensions: 56.5mm x 65mm

Applications

• Shelf label
• AD label
• IoT applications which requires remote refreshing
