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 […]

ESP32 may soon get an open-source WiFi MAC layer

Most, if not all, WiFi hardware relies on closed-source binary blobs including ESP32 wireless MCU, but there’s now work underway to reverse engineer a WiFi MAC layer for the ESP32 to make it a truly open-source platform. Espressif ESP32 wireless microcontrollers already have an open-source framework (ESP-IDF) and toolchain, people can customize the code to some extent, but this excludes the wireless bits (Wi-Fi, Bluetooth, low-level RF functions) that are distributed as closed-source precompiled libraries integrated into the firmware. There were some efforts to provide an open-source stack for the BL602 chip but it never went anywhere, and the ESP32 may become the first target with an open-source driver without any blobs, excluding FPGA-based projects such as OpenWiFi. The early-stage implementation currently supports the following features: Sending WiFi frames Receiving WiFi frames Send an ACK packet as a reply to packets that are sent to the ESP32 Connect to an […]

LILYGO Mini E-Paper Core IoT controller gets ESP32-S3 wireless microcontroller

LILYGO Mini E-Paper Core has gotten an upgrade to the ESP32-S3 wireless microcontroller. The IoT controller was first introduced in 2021 with an ESP32-PICO-D4 system-in-package, a 1.02-inch E-Paper display, and a few GPIOs on the back, and the company kept the same design for the ESP32-S3 model called “Mini E-Paper Core S3”. The tiny ESP32-S3 IoT controller can still be used for integrated into your own project, and the company also provides several shields with nRF24L01 2.4GHz wireless or 433/868 MHz “LoRa” connectivity to transform the device into a longer range IoT device.

WeAct ESP32H2-N4 – A $6 Bluetooth 5.2 LE, Zigbee 3.0, and Thread development board

WeAct ESP32H2-N4 is a low-cost ESP32-H2 development board with Bluetooth 5.2 LE, Zigbee 3.0, and Thread connectivity with a design very similar to the one of Espressif Systems’ ESP32-H2-DevKitM-1 development board, but sold for just $5.70 plus shipping. The ESP32-H2 wireless microcontroller is basically the little brother of the ESP32-C6 without WiFi and aims at low-power nodes in short-range IoT networks. We have previously seen it in Espressif hardware like the aforementioned ESP32-H2-DevKitM-1 and the ESP Thread Border Router board combining ESP32-H2 & ESP32-S3 wireless chips, but so far not in third-party boards, and WeAct ESP32H2-N4 changes that.
