Silicon Labs MG26, BG26, and PG26 Cortex-M33 AI microcontrollers offer up to 3200KB flash, 512KB RAM, 64 GPIO’s

Silicon Labs MG26 BG26 P26 Cortex M33 microcontrollers

Silicon Labs has announced the xG26 family of Cortex-M33 wireless SoCs and MCUs that consists of the multiprotocol MG26 SoC, the Bluetooth LE BG26 SoC, and the PG26 general-purpose MCU without wireless connectivity, and features double the flash and RAM of the Silicon Labs xG24 devices. The xG26 family also comes with double the number of general-purpose input/output (GPIO) pins as the xG24 to enable engineers to build more complex devices in combination with the larger flash and memory reaching up to 3200 KB and 512KB respectively and also integrates a Matrix Vector Processor (MVP) for AI/ML hardware acceleration and Math functions. Silicon Labs MG26 and BG26 wireless SoCs MG26 and BG26 key features and specifications: MCU core – Arm Cortex-M33 @ 78 MHz AI/ML accelerator – Matrix Vector Processor that is 8x faster and 6x lower power than Cortex-M33 processing, and supports an MVP Math Library for non-ML workloads […]

u-blox ALMA-B1 and NORA-B2, Bluetooth 5.4 LE modules are based on Nordic nRF54H20 and nRF54L15 SoCs

u-blox ALMA-B1 and NORA-B2 modules

Wireless communication solutions provider, u-blox has added two new modules to its Bluetooth LE portfolio with the ALMA-B1 and NORA-B2 modules built upon the latest low-power wireless nRF54 chips from Nordic Semiconductor.  Both modules come in a portable, power-efficient layout and support Bluetooth 5.4 and 802.15.4 (Thread, Matter, Zigbee). The ALMA-B1 and NORA-B2 BLE modules are powered by the low-power nRF54H20 and nRF54L15 SoCs, respectively. This enables them to provide IoT devices with sufficient processing power for edge computing and machine learning without the need for external components. u-blox claims that the ALMA-B1 module provides “more than twice the processing power of previous Bluetooth LE modules” and can replace general-purpose microcontrollers in compact solutions. Also, the NORA-B2 reportedly “consumes up to 50% less current compared to previous generations of Bluetooth LE modules,” leading to longer battery life or smaller batteries in end products. Both modules are classified as open CPU […]

ESP32-C5 beta board features 2.4GHz and 5GHz SMA antenna connectors, two USB-C ports

ESP32-C5 test board

Espressif ESP32-C5 microcontroller was announced in June 2022 as the first dual-band WiFi 6 IoT chip from the company. It’s been quiet since then, but things are about to change as the ESP32-C5 beta board’s documentation has very recently been released. The ESP32-C5 was initially announced as a dual-band WiFI 6 and Bluetooth 5.0 LE SoC, but the user manual for the beta board indicates that it also supports Zigbee 3.0 and Thread 1.3, so there’s an 802.15.4 in the wireless microcontroller. The ESP32-C5 board itself features two SMA connectors for 2.4 GHz and 5GHz antennas or test equipment, two USB-C  ports, two 12-pin GPIO header, Boot and Reset buttons, an RGB LED, and a 2-pin header for current measurements. ESP32-C5 beta board specifications: SoC – ESP32-C5-BETA3 CPU – Single-core 32-bit RISC-V processor @ up to 240 MHz Memory – 400KB SRAM on-chip Storage – 384KB of ROM on-chip, support […]

Arduino Nano Matter board specifications and price announced

arduino nano matter board

The Arduino Nano Matter is the product of a collaboration between Arduino and Silicon Labs. The Nano Matter board was announced in January and is powered by SiLabs’ MGM240S chip. It offers multiple wireless connectivity options such as Matter, OpenThread, and Bluetooth Low Energy. Support for the Matter standard is the Nano Matter board’s key offering. Matter is an open-source, connectivity protocol that lets smart home devices from different manufacturers interoperate seamlessly. The 45mm x 18mm board leverages dual-mode connectivity, with IEEE 802.15.4 (Thread) for mesh networking and Bluetooth Low Energy for short-range communication. It is targeted at the Internet of Things, home automation, professional automation, environmental monitoring, and climate control applications. Prospective industrial applications include machine-to-machine interoperability, machine status monitoring, and worker status optimization. Arduino Nano Matter specs: MPU – SiLabs MGM240SD22VNA MCU core – 32-bit Arm Cortex-M33 with DSP (digital signal processing) instruction and FPU (floating-point unit) @ […]

$6.99 Waveshare’s ESP32-C6-Pico Board resembles Raspberry Pi Pico board

Waveshare ESP32 C6 Pico Devlopment Board

Waveshare’s ESP32-C6-Pico and ESP32-C6-Pico-M development boards are equipped with the ESP32-C6-MINI-1 module supporting Wi-Fi 6(802.11ax), Bluetooth 5, Zigbee 3.0, and Thread 1.3, and inspired by the Raspberry Pi Pico form factor. They can be powered either through USB Type-C or an external 5V DC supply connected to the pins. Previously we have written about similar ESP32-C6-based boards like the SparkFun Thing Plus, ePulse Feather C6, and WeAct ESP32-C6 dev board. However, these boards are priced way over the $6.99 that Waveshare is offering. One exception is the DFRobot’s FireBeetle 2 ESP32-C6 board, which cuts costs by using the IC directly instead of the fully shielded ESP32-C6-MINI-1 module. Waveshare’s ESP32-C6-Pico board specifications: Wireless module – ESP32-C6-MINI-1 SoC – ESP32-C6H4 32-bit RISC-V microprocessor up to 160 MHz with 320KB ROM, 512KB HP SRAM, 16KB LP SRAM, 4MB flash Wireless – 2.4 GHz WiFi 6 with Target Wake Time (TWT) support, Bluetooth 5.3 LE and […]

Waveshare ESP32-H2-DEV-KIT-N4-M – A Low-cost ESP32-H2 development board going for $6.65

Waveshare ESP32 H2 DEV KIT N4 M Dev Board

The Waveshare ESP32-H2-DEV-KIT-N4-M is a development board based on the ESP32-H2, available for only $6.65 on Aliexpress, but you’ll also find it on Amazon and Waveshare’s official store. This is a significant price drop compared to last year’s official Espressif ESP32-H2-DevKitM-1 board, which was priced at $10 without including shipping costs and with a similar design. In 2021, Espressif Systems introduced the ESP32-H2 to the world. However, it wasn’t until 2023 that they released their first development board. Since then, there haven’t been many products built around this new module. Some exceptions include the Olimex ESP32-H2-DevKit-LiPo, LILYGO T-Panel, and the ESP Thread Border Router/Zigbee Gateway board, all of which feature the ESP32-H2 chip. Waveshare ESP32-H2-DEV-KIT-N4-M specifications: Wireless module – ESP32-H2-MINI-1 MCU – Espressif Systems ESP32-H2 32-bit RISC-V microcontroller at up to 96 MHz with 320 KB SRAM, 128 KB ROM, 4 KB LP memory, Bluetooth 5.2 LE/Mesh, and 802.15.4 (Zigbee/Thread/Matter) radios.
