Sub-gigahertz Wi-Fi just gained a little more reach in North America. Morse Micro has unveiled the MM8108-M20, a Wi-Fi HaLow module built around its MM8108 RISC-V SoC and paired with a high-power amplifier rated at 28.5 dBm. That is a 2.5 dB bump over competing MM8108 designs like the Quectel FGH200M, which the company says should stretch usable range by roughly a third in line-of-sight scenarios. A surface acoustic wave filter tuned to the 902 to 928 MHz band keeps the module aligned with FCC and IC rules, and the higher transmit ceiling exploits headroom that regulators outside the US and Canada do not permit.
The radio itself is standard IEEE 802.11ah territory: 1, 2, 4, and 8 MHz channels in the 850 to 950 MHz sub-GHz license-exempt range, BPSK through 256-QAM modulation, and a theoretical 43.3 Mbps ceiling at the widest channel. Both access point and station modes are supported, and the module ships with WPA3 and Opportunistic Wireless Encryption baked in. Host integration goes through USB 2.0, SDIO 2.0, or SPI, and the LGA package measures 18.5 x 14 mm (0.7 x 0.6 inches), small enough to drop onto a carrier board next to a Raspberry Pi or other SBC.
For the open hardware crowd, the more interesting story is software. Morse Micro maintains an open-source Linux driver that hooks into the mac80211 stack, which has made the company's silicon the default choice for hobbyist HaLow add-ons aimed at Raspberry Pi, Radxa, and Khadas boards. The driver builds into two kernel modules, morse.ko for SPI and SDIO bus communication and dot11ah.ko for the 802.11ah MAC layer, and received two releases in May 2026, versions 1.17.8 and 1.17.9, alongside updated firmware binaries and a HaLow-aware fork of hostap that ships S1G-enabled versions of hostapd and wpa_supplicant required for access point and station configuration under Linux. morse-feed wraps the driver, firmware, and tools into an OpenWrt package feed that also includes a HaLow-aware LuCI web interface, with Raspberry Pi 4 covered by Morse Micro's official OpenWrt 23.05 SDK. Raspberry Pi 5 support requires kernel 6.6 and bcm2712 hardware definitions not yet in the official SDK, a gap a community backport project (buildwithparallel/openwrt-morse-rpi5) currently fills. A separate community port (dustyrobotics/morse-ubuntu) packages the driver, firmware, and S1G-aware userspace tools for Ubuntu 24.04 on ARM64, with reported use on the Particle Tachyon and Nvidia Jetson Orin Nano. A higher-output module fits neatly into that ecosystem for anyone building long-range mesh links, off-grid LoRa-adjacent sensor networks, or self-hosted camera deployments where Wi-Fi 6 simply will not punch through enough walls or trees.
Morse Micro is positioning the MM8108-M20 at surveillance cameras and HaLow access points like the HaLowLink 2, which already advertises kilometer-class coverage. The Sydney-based company has not yet posted a product page, supply voltage, or pricing, with details limited to the launch announcement dated 2026-06-01. It is also the first module Morse Micro has built and branded itself, rather than licensing reference designs to OEM partners.
