SB Components is back with yet another crowdfunding campaign this time with the Microflex MCUs USB development boards all with the same tiny form factor and offered with a choice of five microcontrollers namely Raspberry Pi RP2040, ESP32-S3, ESP32-S2, ESP32-C3, or ESP32-C6. Microflex MCUs share the same layout with a USB-C port for power and programming, a built-in RGB LED, two buttons for Boot and Reset/User, and two rows of 10-pin with through and castellated holes to access the GPIOs and power signals such as 5V, 3.3V, and GND. But they differ in terms of the processor used, wireless features, and available I/Os as shown in the table below which sadly lacks any information about the flash and eventual PSRAM… The illustration below includes some more details for the Micro-C6 with the main components, ports, and a pinout diagram. Programming the firmware for the ESP32-series can be done through the […]
RoomSense IQ – An ESP32-S3 modular room monitor with mmWave radar presence detection (Crowdfunding)
RoomSense IQ is a modular room monitor for presence-based home automation based on the ESP32-S3 module with Bluetooth Wi-Fi connectivity. It uses physical presence detection to automate your smart home devices. It comes with multiple sensors that can be used to detect human activity and track ambient light, temperature, and humidity levels. It uses mmWave radar technology to determine when rooms are empty and when they are occupied. It also features built-in temperature, humidity, and light sensors for indoor climate monitoring and control. Rather than relying on schedules, or voice detection, RoomSense IQ triggers automations or alerts based on whether people are in a room or not. It is therefore possible to set it to automatically turn off lights or air conditioning in rooms that are empty to save on energy. In addition, the device offers distance to target measurement that can be adjusted to trigger certain actions. RoomSense IQ […]
Arduino Portenta X8 achieves EU’s Cyber Resilience Act (CRA) compliance
Foundries.io, in collaboration with Arduino, has integrated its security software into the Portenta X8, making it the first system-on-module (SoM) to achieve CRA Compliance with the European Union’s Cyber Resilience Act (CRA). Last year, we covered the Portenta X8, Arduino’s first board with an Arm processor running Linux with expansion capabilities with add-ons such as the Portenta HAT Carrier Board, and you’ll find more details about the hardware in those posts. This new EU’s CRA specifies minimum security for all IoT devices in Europe from 2025. This includes: Establish standards for secure products with digital elements throughout the EU. Require manufacturers to focus on security at every stage of a product’s life. Increase user awareness of a product’s cybersecurity features. Demand that Original Equipment Manufacturers (OEMs) quickly address vulnerabilities in devices already in use. All these rules will be applicable for the full lifespan of the devices. Under the upcoming […]
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. Mini E-Paper Core S3 specifications Wireless SoC – Espressif Systems ESP32-S3FN4R2 CPU – Dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration Memory – 512KB RAM, 2MB PSRAM Storage – 4MB flash Wireless – 2.4 GHz WiFi 4 and Bluetooth Storage – MicroSD card socket Display – 1.02-inch e-paper display with 128×80 […]
Robustel introduces EG5101 and EG5200 Debian 11 industrial IoT gateways with 4G LTE cellular connectivity
Robustel introduced the EG5101 and EG5200 industrial IoT gateways running Debian 11 a few weeks ago, both with 4G LTE cellular connectivity, but the NXP i.MX 6ULL-based EG5101 has a more compact design, while the NXP i.MX 8M Plus-powered EG5200 provides more I/Os and resources. Expanding the earlier EG5100, EG5120, and LG5100 models from the company, the two edge computing gateways target Industry 4.0 and smart infrastructure applications and enable real-time analytics at the edge with lower latency than running workloads in the cloud. Robustel EG5101 and EG5200 SoC/Memory/Storage EG5101 NXP i.MX 6ULL Cortex-A7 32-bit processor @ 792 MHz 512MB to 1024MB DDR3 8GB eMMC flash EG5200 NXP i.MX 8M Plus quad-core Cortex-A53 64-bit processor @ 1.6 GHz with 2.3 TOPS NPU 4GB DDR4 32GB eMMC flash, microSD card socket Connectivity EG5101 1x 10/100 Mbps Ethernet port 4G LTE with 1x SMA-K antenna connector, 2x Mini SIM (2FF) EG5200 5x […]
nRF7002 Expansion Board adds WiFi 6 to Nordic Thingy:53 devkit
Nordic Semi keeps adding more nRF7002 WiFi 6 boards with the launch of the nRF7002 Expansion Board adding WiFi 6 connectivity to the Thingy:53 IoT prototyping platform and transforming it into an all-in-one wireless devkit with Matter, Bluetooth Low Energy, Thread, and WiFi 6 support. The new “nRF7002 EB” board follows the nRF7002 DK development kit combining the nRF7002 WiFi 6 with nRF5340 multiprotocol wireless SoCs, and the nRF7002 EK evaluation kit in Arduino UNO shield form factor adding WiFi 6 to existing Nordic development kits. nRF7002 Expansion Board specifications: Chipset – nRF7002 Wi-Fi Companion IC with support for features such as OFDMA (Orthogonal Frequency Division Multiple Access), Beamforming, Target Wake Time, and SSID-based locationing Antenna – 2.4 GHz / 5 GHz ceramic antenna I/Os Castellations for all pins on nRF7002 Thingy:53 expansion connector with SPI and a 3-wire coexistence interface to allow seamless coexistence with other wireless protocols Misc […]
AirGradient ONE Kit Review – An open-source indoor air quality monitor
The product we are reviewing today is the “AirGradient ONE” air quality monitor kit which is an updated version of the earlier AirGradient air quality monitor. The device is equipped with sensors from Sensirion and Plantower, allowing it to measure many air quality parameters such as CO2, PM2.5, TVOCs, NOx, temperature, and humidity. It is an indoor air quality monitor that is both open-source software and open hardware. This means that the Arduino source code, schematic diagrams, PCB, and 3D models of the enclosure are available to developers. AirGradient ONE DIY Kit Unboxing The device was packaged within a cardboard box, with a greeting card from the manufacturer. The card features a QR code linking to a webpage with the installation guide. Since I requested the Kit version (there’s also a fully assembled model), some sensors were not pre-assembled and they were well-packaged in separate seals. The main PCB was […]
