Arduino has released a new power management library designed for Arduino Pro modules to help users monitor battery usage, fine-tune charging parameters, and optimize the power consumption of their Arduino code by notably enabling sleep and standby modes on supported devices. Currently, the Arduino Portenta H7 boards, the Arduino Portenta C33, and the Nicla Vision module are supported by the new power management library. The company explains some boards consume under 100 microamperes in deep sleep mode enabling months or even years of continuous runtime on a single charge, so making use of those features is important to lower the power consumption of battery-powered IoT devices and wearables. Arduino power management library key features: Battery monitoring – Reports battery metrics such as voltage, current, percentage, and temperature. Battery health tracking – Monitors battery health with detailed insights into temperature and reported capacity. Charging control – Monitors and adjusts charging parameters […]

Using RISC-V cores on the Raspberry Pi Pico 2 board and RP2350 MCU – From blinking an LED to building Linux
Raspberry Pi Pico 2 was released last month with a Raspberry Pi RP2350 microcontroller equipped with two Arm Cortex-M33 cores and two 32-bit RISC-V “Hazard3” cores with up to two cores usable at any time. So in this guide, we’ll show how to use the RISC-V cores on the RP2350 MCU, compare their performance against the Arm Cortex-M33 cores, and even build Linux for RISC-V for RP2350 boards that have PSRAM. Apart from the extra memory and more powerful cores, plus new features related to security and the HSTX interface, the Raspberry Pi Pico 2 and Pico will be very similar to the end user and the instructions in our article “Getting Started with Raspberry Pi Pico using MicroPython and C” remain valid. I don’t think there’s a MicroPython RISC-V image yet, so we’ll focus on running C programs on the RISC-V cores. A quick check with the Arm cores […]
