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 […]

Quectel LG290P is the world’s first quad-band GNSS module (L1, L2, L5, and E6)
The Quectel LG290P is a quad-band, multi-constellation, high-precision, real-time kinematic (RTK) GNSS module that supports GPS, GLONASS, Galileo, BDS, QZSS, and NavIC constellations. A typical GNSS module like the SparkFun GNSS L1/L5 can receive signals from only one or two frequency bands, but the Quectel module can receive signals from four different frequency bands (L1, L2, L5, and E6) simultaneously and features built-in anti-jamming technology for improved signal reception in challenging environments. All these measures make this chip suitable for high-precision navigation applications like autonomous robots, UAVs, precision agriculture, surveying and mapping, and autonomous driving. Previously we have written about higher precision GPS modules like the SparkFun RTK EVK module, SparkFun RTK Torch module, the Cavli C17QS IoT GNSS module and much more feel free to check those out if you are interested in those topics.

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.
