Notes

Host-driven Raspberry Pi radio HAT with an E22-900M33S module and a 902–926 MHz band-pass filter.[1][3]

The maker publishes up to 29.8 dBm after the filter at power setting 9 and notes that host power affects the result. The module itself is rated at 33 dBm.[1][6]

The design is superseded by Zebra Hat. The maker restricts US use to licensed Part 97 amateur-radio operation; it is not certified for unlicensed use.[1] Designed by wehooper4.[1]
