STMicro STM32WL5MOC SiP Module is pre-certified for LoRaWAN & Sigfox networks

STMicroelectronics has recently introduced the STM32WL5MOC system in package (SiP) module with a dual-core STM32 microcontroller, sub-1 GHz RF radio, power supply, and passive components into a 10×10 mm LGA package. According to ST, the new chip uses the STM32WL module which we have seen used in Arduino MKR-inspired MKR Windy board, smart building, and many other LoRa devices. STMicroelectronics’ STM32WL, an Arm Cortex-M0+ microcontroller, operates in sub-GHz ISM bands (413-479MHz, 826-958MHz, and 169MHz later in 2024) for protocols like wireless M-Bus (mode N) and Wize. It supports multi-protocol and multi-modulation (4-(G)FSK, 2-(G)FSK, (G)MSK, DBPSK, DSSS, OOK, ASK) for various wireless standards (Sigfox, KNX, WiSun, mioty, M-Bus, etc.) and introduces power-saving features for up to 15 years of battery life. STM32WL5MOC SiP module specifications: Core Specifications: STM32WL55JC SoC with 32-bit Arm Cortex-M4 and Cortex-M0+ CPUs, up to 48 MHz. Adaptive real-time accelerator (ART Accelerator) for efficient flash memory execution. DSP instructions […]

Quectel FGH100M Wi-Fi HaLow module based on Morse Micro MM6108 receives CE and FCC Certifications

Quectel and Morse Micro's FGH100M Wi Fi HaLow Module

In a collaboration, Quectel Wireless Solutions and Morse Micro have developed the FGH100M a Wi-Fi HaLow module, powered by Morse Micro’s MM6108 SoC. This module has achieved CE certification in Europe and FCC approval in the US, meeting high safety and environmental standards. After reading through the press release, I initially thought the 802.11.ah WiFi, known as WiFi HaLow, would be similar to other LPWAN standards like LoRaWAN or Sigfox. However, further research showed that Wi-Fi HaLow, operating in the 900 MHz band, was first announced in 2014 and got its name in 2016. However, in the following years, there wasn’t much interest in this wireless standard. But starting from 2021, it’s becoming more popular, and we’ve seen many HaLow-based products like a mini PCIe card, a WiFi HaLow development board, and a gateway kit to extend the range of IP cameras, and also ALFA Network’s AHPI7292S Raspberry Pi HAT […]
