RAKwireless open sources RUI3 multi-target IoT development platform

RAKwireless has made its RUI3 IoT software development platform open-source so that customers or users can implement “nice-to-have” features on top of the features already implemented by the company which could make it even more versatile in a wider range of IoT scenarios. Introduced in 2022, the RAK Unified Interface v3, or RUI3 for shorts, is a modular IoT platform based on the Arduino SDK with additional functions for IoT connectivity and low power that supports a variety of devices and applications. So developers can learn the language, code once, and use the same software on multiple WisBlock core platforms including Nordic Semi nRF52, STM32, ESP32, and Raspberry Pi RP2040 instead of having to juggle between different the Arduino BSP, the ESP-IDF framework, Nordic nRF Connect SDK, or Raspberry Pi C SDK. Users could already use the RUI3 firmware with the RAK3172 (STM32), RAK4630/RAK4631 (nRF52), or RAK11720 (Apollo3) WisBlock Core […]

Comparing the latency of various wireless standards

If you’ve ever wondered which wireless standard may deliver the smallest lag (latency) when transmitting small packets, we’ve now gotten an answer thanks to Scott at Electric UI who benchmarked various wireless links in common MCU development boards. More specifically the following hardware and wireless standards were tested: SiliconLabs 10×0-GM RF+8051 microcontroller with 240–960 MHz EZRadioPRO transceiver running SiK firmware HopeRF RFM95W LoRa module (on an Adafruit Breakout board) connected to an STM32F429 MCU Nordic Semi nRF24L01 2.4GHz transceiver module ESP32 board for ESP-NOW and WiFi testing is shown as ESP32 WS (WebSockets) or ESP32 TCP in the chart below. Raspberry Pi boards were also used for comparison ESP32-C6 board for 802.15.4 transfers (Thread) ESP32 and HC-05 modules for Bluetooth SPP (Serial Port Profile) ESP32 board with NimBLE and Bluedroid stacks and nRF52 for Bluetooth LE testing Here are the results for 12 bytes, 128 bytes, and 1024 bytes data transfers.

Entry-level Industrial Shields ESP32 PLC 14 sells for 100 Euros

Boot & Work Corp has just introduced an entry-level PLC based on ESP32 wireless microcontroller with the “Industrial Shields ESP32 PLC 14” that comes with seven inputs and five outputs, as well as I2C, RS485, Ethernet, WiFi, and Bluetooth communication interfaces. We first covered “Industrial Shields” automation devices in 2017 when the company introduced panel PCs based on Banana Pi, Raspberry Pi, and Hummingboard (NXP i.MX 6) SBCs, as well as a few Arduino and Raspberry Pi PLCs. Boot & Work Corp then launched a Raspberry Pi 4-based PLC in 2021, and now the company has introduced the ESP32 PLC 14 part of a larger family of PLC devices as we’ll see further below. ESP32 PLC 14 specifications: Wireless module – ESP-WROOM-32U with ESP32 dual-core wireless microcontroller @ 240 MHz with 4MB SRAM, 4MB flash, 2MB PSRAM I/Os through terminal blocks 4x Digital Outputs 12/24 V DC (can also act […]

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

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 […]

$16 Grove Vision AI V2 module features WiseEye2 HX6538 Arm Cortex-M55 & Ethos-U55 AI microcontroller

Seeed Studio’s Grove Vision AI V2 module is based on the HiMax WiseEye2 HX6538 dual-core Cortex-M55 AI microcontroller with an Arm Ethos-U55 microNPU and features a MIPI CSI connector for an OV5647 camera. It is designed for AI computer vision applications using TensorFlow and PyTorch frameworks and connects to hosts such as Raspberry Pi SBCs, ESP32 IoT boards, Arduino, and other maker boards over I2C. We tested the previous generation Grove Vision AI module based on the 400 MHz HX6537-A DSP-based AI accelerator using the SenseCAP K1100 sensor prototype kit with LoRaWAN connectivity, and managed to have the kit perform face detection and send the data over LoRaWAN. The Grove Vision AI V2 builds on that but with a modern Arm MCU core and more powerful AI accelerator that can run models such as Mobilenet V1/V2, Efficientnet-lite, and Yolo v5 & v8 using the SenseCraft low-code/no-code platform. Grove Vision AI […]

2023 Year in review – Top 10 posts, statistics, and what to expect in 2024

It’s the last day and last article of the year, so we will look at some highlights of 2023, some traffic statistics on the CNX Software website, and speculate what interesting developments may happen in 2024. Looking back at 2023 The semiconductor shortage that had happened since 2020 started to fade away in early 2023, and supplies for most electronics components and devices seem to be adequate at this time, so that was a bright spot this year, and hopefully, it will stay that way in 2024 despite geopolitical tensions. We did not have any super exciting new Arm application processors from Rockchip, Amlogic, or Allwinner announced this year, although the Amlogic S928X penta-core Cortex-A76/A55 CPU started to show up in some 8K TV boxes. The launch of the Raspberry Pi 5 SBC with a Broadcom BCM2712 quad-core Cortex-A76 processor was probably the main highlight for Arm on this side […]

Theengs Bridge BLE to MQTT gateway supports Home Assistant, OpenHAB, Jeedom, NodeRed, and more

The Theengs Bridge is a new WiFi & Ethernet BLE to MQTT gateway running the open-source OpenMQTTGateway firmware, compatible with a range of sensors, and supporting Home Assistant, OpenHAB, Jeedom, NodeRed, and other MQTT-compatible systems. It follows the Theengs Plug smart socket introduced at the beginning of the board with many of the same features (minus the socket part…) but adds Ethernet and an external antenna for improved range, and improves modularity with a Grove I2C connector and mounting holes for a LoRa-E5-based Grove module and a prototyping area where you can solder your own circuitry with DIP components. Theengs Bridge specifications: Wireless module MCU – ESP32 microcontroller with WiFi and Bluetooth Storage – 8MB flash PCB antenna and u.FL antenna connector Connectivity 10/100M Ethernet RJ45 port 2.4 GHz WiFi 4 and Bluetooth LE with 6dBi 50Ohm external antenna Optional LoRa module via Grove I2C connector MQTT protocol Expansion – […]

International Black Friday and Cyber Monday 2023 deals and coupon codes

We’ve been writing about international Black Friday and Cyber Monday deals and coupon codes since 2014, as US-centric promotions such as Amazon’s Black Friday and Cyber Monday deals are not always available to the international audience of CNX Software. So once again, we’ve searched at Black Friday and Cyber Monday 2023 international promotions and discount codes from specific manufacturers as well as popular online stores such as Aliexpress, Banggood, and others. Aliexpress Black Friday and Cyber Monday event Aliexpress will have a Black Friday (and Cyber Monday) event in 2023, but we have limited details at this time since it will only start on November 23, contrary to some of the other deals we’ll feature below which are already up and running. But the event will have two periods: Nov 20-22 PT – Warm Up event where users can find and add items to the cart before purchasing during the […]
