Summary

The SIM8202G-M2 5G HAT (B) is a Raspberry Pi add-on with an M.2 B-key connector for 5G/4G/3G communication, four antenna ports and a USB 3.1 port. It supports the SIM8202G-M2, SIM8262E-M2 and RM50XQ series modules.

Technical overview

  • M.2 B-key connector compatible with 5G modules from the RM500U-CN, RM500Q-GL, RM500Q-AE and RM502Q-AE series.
  • USB 3.1 port (backward compatible with USB 2.0) for connecting to a PC, Raspberry Pi or Jetson Nano host.
  • Two SIM card slots: dual-card single standby; switchable via AT command where the module supports it.
  • Four IPEX-4 antenna connectors for 3G/4G/5G/GNSS.
  • Onboard voltage level translator for UART, PWR and RST control pins, enabled through a DIP switch.
  • USB-C input for external power (5 V / 3 A); power switch selectable between USB and EXT PWR modes.
  • Power on/off switch, reset button and LED indicator for monitoring operating status.
  • Built-in cooling fan cools both the Raspberry Pi and the 5G module simultaneously.
  • Supported operating systems: Windows, Linux, Android; protocols include TCP/IP, IPv4/IPv6, Multi-PDP, FTP/FTPS, HTTP/HTTPS, MQTTS, DNS, SSL3.0.
  • Data rates: 5G Sub-6 GHz up to 2.4 Gbps downlink / 500 Mbps uplink; LTE up to 1 Gbps downlink / 200 Mbps uplink.

Commands and examples – verify before use:  

lsusb
ls /dev/ttyUSB*

Notes and version constraints

  • Exact band and regional support depends on the chosen 5G module; select modules according to local operator network coverage and supported frequency bands.
  • Dual-SIM functionality requires module support; not all supported modules support two cards.
  • Audio function is supported by the SIM82XX series but not by the RM50XX series.
  • When handling IPEX antenna connectors: gently wiggle side-to-side and pull straight out without force; connectors are fragile.
  • Fan noise may increase after prolonged use as bearing lubricant evaporates – this is normal, not a fault.
  • Modules without USB function (PCIe only) are not supported; when using other modules, verify pin compatibility by actual testing.
