Waveshare has recently launched DDSM Driver HAT (B), a compact Raspberry Pi DDSM (Direct Drive Servo Motor) motor driver designed specifically to drive the DDSM400 hub motors. This board is built around an ESP32 MCU and supports wired (USB and UART) and wireless (2.4GHz WiFi) communication. Additionally, the board features a physical toggle switch, which lets it choose between the ESP32 control or USB control modes. On ESP32 control mode you can control the device through a built-in web application. In the USB control mode, the motor driver can be controlled via USB from a host computer sending JSON commands. An XT60 connector is used to power the board, and programming is done through a USB-C port that connects to the ESP32. The board is suitable for robotics projects, especially for mobile robots in 6×6 or 4×4 configurations.

Ditronix’s IPEM PiHat turns your Raspberry Pi into a mains power energy monitor (Crowdfunding)
The IPEM PiHat is a HAT (Hardware Attached on Top) board for the Raspberry Pi that turns the single-board computer into a mains power energy monitor with four CT clamps. It provides an accurate way to track energy usage in home, office, and solar energy systems and is compatible with single-phase, two-phase, and three-phase electrical systems. The Raspberry Pi-based power energy monitor uses CT (current transformer) cable clamps to sample and measure data which can be used to report and analyze electric energy usage. This data can be used to save and divert energy to reduce costs and inefficiencies. The system is easy to set up and does not require a professional electrician. It uses a CT current clamp clipped over the building’s main power cables and connected to the local mains circuit for voltage and frequency measurement. The add-on board comes in two variants: IPEM PiHat and IPEM PiHat […]

NXP MCX L14x and MCX L25x ultra-low-power Cortex-M33 MCUs target energy harvesting and battery-powered devices
NXP Semiconductors has launched the MCX L series of ultra-low-power Arm Cortex-M33 MCUs with the MCX L14x and MCX L25x SKUs. The new series offers similar peripherals as the rest of the MCX portfolio but uses a new “power management architecture that supports always-on, battery-powered applications” The MCX L series uses a dual domain architecture, with “real-time processing and ultra-low-power sensing functions in a single device.” The Arm Cortex-M33 core supports real-time processing functions while the Arm Cortex-M0+ core offers always-on operation in the ultra-low-power sense domain. The new microcontrollers reportedly use three times less power than their predecessors. The ultra-low-power series is targeted at energy-constrained applications, powered by a battery, ultracapacitor, or power harvesting circuit. These include building control, industrial sensing, smoke and fire alarms, flow meters, smart appliances, and motion detectors.
