XIAO Powerbread is a breadboard power supply and meter based on XIAO RP2040 or ESP32 USB-C board

XIAO Powerbread power meter for breadboard

The XIAO Powerbread is a breadboard power supply and meter compatible with XIAO RP2040 or ESP32 USB-C boards and equipped with a color LCD display showing real-time voltage, current, and power consumption for 5V and/or 3.3V power rails. Breadboard power supplies are nothing new. We’ve written about several over the years including the Toaster board with adjustable voltage from 5 to 16V, the SwitchTrick switching power supply board, and the MEGO portable breadboard power supply with a built-in battery. The XIAO Powerbread only supports 5V and 3.3V power rails, but its main selling point is its integrated breadboard power meter function. XIAO Powerbread specifications: Supported USB-C modules General purpose MCU – XIAO RP2040, XIAO RP2350 WiFi / Bluetooth MCU – XIAO ESP32S3, XIAO ESP32C3, XIAO ESP32C6 Display – 0.96-inch color TFT LCD with 160×80 resolution and ST7735S SPI controller Power monitoring – 2x TI INA3221 sensors connected over I2C […]

STMicro releases IO-Link actuator board for industrial monitoring and home appliances

STMicro EVLIOL4LSV1 IO-Link actuator board

STMicro has announced the EVLIOL4LSV1 IO-Link actuator board, an STM32G071CB Cortex-M0+ MCU-based reference design for commercial manufacturers with a built-in protocol stack and application software. Aimed at industrial beacons and home-appliance alarms, the EVLIOL4LSV1 combines the L6364Q dual-channel IO-Link transceiver (communications) and IPS4260L intelligent low-side power switch (for driving industrial loads). The EVLIOL4LSV1 IO-Link actuator board is powered by an STM32G071CB Arm-Cortex-M0+ microcontroller that hosts the proprietary stack and application software and communicates with the transceiver and low-side power switch. The evaluation board can be used to test the IPS4260 and L6364Q ICs. It features a 4-pin M12 connector for an IO-LINK master and a 5-pin SWD connector for programming. It can also directly interface with signaling systems, ranging from smart tower lights in factory automation to funnel alarms for quantity monitoring. The onboard transceiver is protected against electromagnetic interference and supports COM2 and COM3 speeds. It offers multiple modes […]

Black Friday and Cyber Monday 2024 – International deals and coupons

While Black Friday and Cyber Monday used to be a US-only event, it changed many years ago, and we’ve been writing about international Black Friday and Cyber Monday deals and coupon codes since 2014, since a large portion of our audience cannot benefit from promotions on Amazon’s Black Friday and Cyber Monday events that will take place from November 21 until December 2 this year. So I’ve gathered some international Black Friday and Cyber Monday 2024 deals and discount coupon codes from relevant manufacturers and popular online stores such as Aliexpress, Banggood, and others. Aliexpress Black Friday and Cyber Monday event Aliexpress’ Black Friday and Cyber Monday 2024 event has already started. There are three periods: Nov 19-21 PST – Warm Up event where users can find and add items to the cart before purchasing during the main event. Nov 22-30 PST – “On Sale” event with discounts up to […]

STMicro STSPIN32G0 3-phase motor controllers support up to 24V for portable appliances, up to 600V for industrial automation

STMicro STSPIN32G0 is a new series of advanced 3-phase motor controllers with variable voltage ranging from 45V to 600V that extend STMicro’s portfolio of devices with an integrated MCU and motor driver. The new series combines a triple-half bridge gate driver with the Arm Cortex-M0+-based STM32G0 microcontroller and is capable of handling six-step and field-oriented control (FOC) algorithms. The integrated design of the STSPIN32G0 series offers cost-savings and “significant BOM area reduction without compromising performance and robustness.” There are two main versions of the STSPIN32G0 series, low-voltage and high-voltage. The low-voltage 3-phase motor controllers include a voltage regulator, one or three shunts, and a gate driver rated at 45V and up to 0.6A. They are mainly targeted at home appliances, power tools, and drones. The high-voltage versions can handle either 250V or 600V, making them suitable for industrial inverters and fans. They are targeted at home appliances, air conditioners, home […]

MicroPython v1.24 release adds support for RP2350 and ESP32-C6 microcontrollers, various RISC-V improvements

Micropython v1.24 with ESP32-C6 and RP2350 support

MicroPython has become one of the most popular ways of programming microcontrollers, and the just-released MicroPython v1.24 adds support for the widely-used Raspberry Pi RP2350 and Espresif ESP32-C6 microcontrollers and a range of other changes. Those include improved RISC-V support with native code generation, an updated Zephyr v3.7.0 RTOS with threading support, unified TinyUSB bindings across ports, a portable UART IRQ API, and enhanced mpremote recursive copy. Damien George goes into more detail about the RISC-V improvements: … include an RV32IMC native code emitter, native NLR and GC register scanning implementations for 32- and 64-bit RISC-V, support for placing RV32IMC native code in .mpy files and also freezing it, and RISC-V semihosting support. Testing for RISC-V is done with the qemu and unix ports, and the support is utilised in the esp32 and rp2 ports. The Raspberry Pi RP2350 comes with both Arm Cortex-M33 and RISC-V cores, and the good […]

Flipper Zero hacking tool gets MicroPython support

Developer and engineer Oliver Fabel has developed a port that is designed to run MicroPython on the Flipper Zero. This port allows users to write programs for Flipper Zero in Python, instead of built-in JavaScript. Till now you can access GPIO, ADC, PWM, the speaker, buttons, the display, and infrared communication with this but it doesn’t have support for NFC or RFID yet, and it’s still under development. Previously we have written about various addon boards for the Flipper Zero like the Mayhem v2, the ESP8266 Deauther board, the CAN bus addon board, and other powerful alternatives of the Flipper like The M1 and the HackBat. Feel free to check those out if you are interested in the topic. The process is simple, and you don’t have to do a firmware update to work with MicroPython, you can download the application from the community-driven Flipper app store and are good […]
