Morse Micro MM8108-M20 high-power Wi-Fi HaLow module delivers up to 28.5 dBm Tx output power
Morse Micro MM8108-M20 is a high-power Wi-Fi HaLow module based on the MM8108 SoC and a high-power amplifier delivering up to 28.5 dBm transmit output power, alongside a surface acoustic wave (SAW) filter tuned for the 902-928 MHz band of the North American market. Other MM8108 modules, such as the Quectel FGH200M Wi-Fi HaLow module, are limited to 26 dBm Tx power, but US and Canada regulations enable higher power transmissions, and by extension longer range. The obvious downside of the MM8108-M20 is that it might be outright illegal or may require a special license in other countries. Morse Micro MM8108-M20 specifications: SoC – Morse Micro MM8108 32-bit RISC-V Host Applications Processor (HAP) Standard – IEEE802.11ah Wi-Fi HaLow Frequency band – 850-950 MHz (Worldwide sub-1 GHz license-exempt range) Operating Modes – Access Point (AP) and Station (STA) Channel Width – 1/2/4/8 MHz Modulation – BPSK, QPSK, 16QAM, 64QAM, 256QAM.
