ME7 with Raspberry Pi

1. USB Connectivity & Compatibility

  • Is the M7E fully compatible with a Raspberry Pi 4 when connected over USB?
  • Are there any driver or firmware considerations for Raspberry Pi OS (32-bit or 64-bit)?
    2. Power Supply Requirements
  • Does a Pi 4 USB port reliably supply enough current to power the M7E under normal operating loads?
  • If not, would you recommend using a powered USB hub or an external 5 V supply to ensure stable operation in a remote setup?
  • Adding an External Antenna
  • In a future phase, I plan to attach a higher-gain external antenna to extend read range.
  • Will powering a larger antenna significantly increase current draw from the Pi’s USB port?
  • If so, what additional current headroom should I budget for?
    3. Cloud Integration**
  • Does the M7E support continuous tag-read streaming over its USB serial interface at typical asset-management scan rates?
  • Are there any recommended settings or buffering strategies to ensure reliable data capture and minimal packet loss before forwarding to a cloud endpoint?
  • Do you have examples or best practices for integrating the M7E Python on a Raspberry Pi for uploading tag data to AWS, Azure, or another cloud service?

Yep, not really…just identifying which COM port it is, etc

No, pi 4 won’t supply enough for most use-cases (but does supply enough for close-range testing). We recommend an external 5v supply, see the power section in the guide.

The next section covers using an external antenna . Current draw from the module should be handled as above (5v external)…we recommend this one UHF RFID Antenna (RP-TNC) (also get the adapters listed on its page)

It can read up to 300 tags at once…and you can implement code on the Pi to do packet verification steps or what-have-you, but we don’t have much specific advice for cloud integration (though presumably it should be fairly straightforward…add the Pi to your could service, pipe its data and voila)
