NBIOT/LTE-M Air Monitor – A solar-powered ESP32-S3 multi-sensor board with SIM7080G NB-IoT & LTE-M modem

The NBIOT/LTE-M Air Monitor is a solar-powered device that utilizes a combination of ESP32-S3 and SIM7080G modules for remote environmental monitoring. It monitors and transmits environmental parameters such as temperature, humidity, CO2, TVOC, and light intensity using low-power wide-area network (LPWAN) technology ensuring efficient power consumption, durability, and reliable data transmission. Previously we have written about similar environment monitor devices like the Airlytix ES1,  Sonoff SC WiFi, V-Air Monitro, and devices like Arduino MKR IoT Carrier Rev2, Radair mini gateway, and Nicla Sense ME  designed for environment monitoring applications. Feel free to check those out if you are interested in this type of product.

STMicro EVLDRIVE101-HPD 1.9-inch motor driver board can drive 750W BLDC motors

STMicroelectronics has recently revealed the reference design for “EVLDRIVE101-HPD” their homegrown BLDC motor driver board that can drive up to a 750W BLDC motor. This compact 50 mm (1.9-inch) circular PCB combines STDRIVE101 3-phase, triple half-bridge gate-driver IC with an STM32G0 microcontroller, which is responsible for driving three-phase brushless motors. The driver board supports various motor-control strategies, including trapezoidal and field-oriented control (FOC), with both sensor’ed and sensorless rotor-position detection. Additionally, it has a wide operating voltage range of 5.5V to 75V and includes STL220N6F7 60V STripFET F7 MOSFETs, which have very low Rds(on) for high efficiency. Other features of the board include ultra-low power consumption in sleep mode, a single-wire debug interface, direct firmware update capability, and protection mechanisms such as under-voltage lockout, overtemperature protection, and cross-conduction prevention. All these features make this board suitable for applications like hairdryers, handheld vacuums, power tools, fans, drones, robots, and industrial equipment […]

Firefly ROC-RK3576-PC low-profile Rockchip RK3576 SBC supports AI models like Gemma-2B, LlaMa2-7B, ChatGLM3-6B

Firefly ROC-RK3576-PC is a low-power, low-profile SBC built around the Rockchip RK3576 octa-core Cortex-A72/A53 SoC which we also find in the Forlinx FET3576-C, the Banana Pi BPI-M5, and Mekotronics R57 Mini PC. In terms of power and performance, this SoC falls in between the Rockchip RK3588 and RK3399 SoCs and can be used for AIoT applications thanks to its 6 TOPS NPU. Termed “mini computer” by Firefly this SBC supports up to 8GB LPDDR4/LPDDR4X memory and 256GB of eMMC storage. Additionally, it offers Gigabit Ethernet, WiFi 5, and Bluetooth 5.0 for connectivity. An M.2 2242 PCIe/SATA socket and microSD card can be used for storage, and the board also offers HDMI and MIPI DSI display interfaces, two MIPI CSI camera interfaces, a few USB ports, and a 40-pin GPIO header. Firefly ROC-RK3576-PC specifications SoC – Rockchip RK3576 CPU 4x Cortex-A72 cores at 2.2GHz, four Cortex-A53 cores at 1.8GHz Arm Cortex-M0 MCU at 400MHz GPU […]

LattePanda Mu Intel N100 SoM and carrier board review – Part 2: Ubuntu 24.04

We’ve already checked out the hardware for LattePanda Mu and tested it on Windows 11 using both the Lite Carrier Board and Full-Function Evaluation in the first part of the review. We’ve now had time to test the LattePanda Mu Intel N100 board with Ubuntu 24.04 to see how it performs in Linux with the following tests:

Initial system information
Benchmarks for CPU, disks, peripherals, and networking (GbE and WiFi)
Web and multimedia usage
Power consumption

Since LattePanda Mu is an x86 machine, we can create a boot disk from the Ubuntu 24.04 ISO as we would on a PC.

Jetway JMTX-ADN8 mini-ITX motherboard features Intel N97 CPU, dual GbE, three display interfaces

The Jetway JMTX-ADN8 is a mini-ITX motherboard built around an Intel N97 (Alder Lake-N) processor. The board supports up to 32GB DDR5 RAM via a single SO-DIMM slot and can drive up to three independent displays powered by Intel UHD graphics. Additionally, it offers dual GbE LAN, nine USB ports both USB3.2 Gen 1 and USB 2.0, and multiple storage and expansion options including M.2 (M-key, E-key, and B-key) and SATA-III. The motherboard also includes PCI expansion and supports Windows and Linux operating systems. In one of our last posts, we wrote about the Jetway JNUC-ADN1, another Intel N97-powered SBC, but in a smaller Next Unit of Computing (NUC) form factor. Other than that we have written about similar motherboards in mini-ITX from factors including Radxa ROCK 5 ITX, MW-100-NAS, and ASRock IMB-A8000 feel free to check those out if you are looking for mini-ITX motherboards.

Forlinx FET3576-C Rockchip RK3576 SoM powers feature-rich OK3576-C board for AIoT applications

Forlinx FET3576-C SoM is a new System-on-Module built around the Rockchip RK3576 SoC which features four Arm Cortex-A72 and four Cortex-A53 cores made from a 22nm lithography process. The SoM is available with 2GB or 4GB of LPDDR4 RAM option and can be equipped with up to 32GB of eMMC storage. Additionally, it has 6 TOPS NPU power and supports standard peripherals like GbE Ethernet, Wifi, Bluetooth, LVDS, MIPI DSI, and much more. All these features make this device useful for IoT, edge computing, digital signage, and many other applications. The new FET3576-C SoM and its OK3576-C development board look very similar to the Forlinx FET3562J-C SoM and related board we covered earlier this month. But the main difference between the two is that the new one is built with the RK3576 SoC whereas the old one is built around the Rockchip RK3562(J) SoC. Previously we also saw that the […]

Seeed Studio Wio Tracker 1110 Dev Kit supports Meshtastic for off-grid communication

The Seeed Studio Wio Tracker 1110 is a dev kit designed to work with the Meshtastic network. The board is built around a Nordic nRF52840 multiprotocol Bluetooth 5.4 SoC and uses the Semtech LR1110 LoRa transceiver for communication. Seeed Studio is selling the Wio Tracker 1110 development board in a bundle with an OLED display and a GNSS receiver, providing everything needed to start experimentation for peer-to-peer LoRa mesh networking. Meshtastic is a free, open-source, decentralized mesh network that uses LoRa radios to establish a low-power, long-range, off-grid communication system in areas without reliable infrastructure. Driven entirely by the community, Meshtastic enables decentralized, encrypted communication without the need for a dedicated router or phone. Previously we have written various versions of the Wio Tracker including the Wio GPS and Wio LTE GPS Tracker. Since Meshtastic projects are becoming popular among developers and enthusiasts, we will likely see many more dev […]
