Low-cost Raspberry Pi 5 HAT+ combines M.2 socket for NVMe SSD and PoE power input

Waveshare POE M.2 HAT+

With a cost of only about $25, Waveshare has recently introduced the PoE M.2 HAT+ for the Raspberry Pi 5, which is much cheaper than the similar N-Fuse PoE HAT that we’ve written about previously. As the name implies, this new Waveshare board supports Power over Ethernet (PoE) and features an M.2 slot to add NVMe SSD storage to the latest Raspberry Pi SBC. This new Waveshare HAT complies with the 802.3af/at standards and can deliver up to 25.5W of power to the Pi 5, enabling both power and network connectivity over a single Ethernet cable. Additionally, it features onboard 5V & 12V header outputs for powering additional devices like cooling fans, and there are also two LEDs for status. A fast storage device and the ability to power the device with ethernet makes this device suitable for applications such as network-attached storage, media centers, and edge computing applications.

Toshiba TCKE9 reusable e-fuse features a fixed over-voltage clamp with adjustable overcurrent limit

Toshiba TCKE9 eFuse Series

Toshiba has recently introduced the Toshiba TCKE9 reusable e-fuse (electronic fuse) series, a new lineup of e-fuse ICs that can be used repeatedly, to protect power supply lines from various electrical faults like overcurrent, overvoltage, overtemperature, and short circuits. These new chips integrate various protection features into a single chip which simplifies circuit design and reduces component count compared to how a traditional protection circuit with multiple components is designed. This new line of products offers different ICs with different voltage ratings and adjustable current settings, alongside two reset modes auto-retry and latching. All these features make this e-fuse useful for applications like laptops, wearables, audio/video equipment, and industrial applications like automation systems, robotics, and many other applications. Toshiba TCKE9 reusable e-fuse Specification Input Voltage – 2.7V to 23V (Maximum – 25V) Output Current – 0 to 4.0A (Adjustable overcurrent limit – 0.5A to 4.0A via external resistor) ON Resistance […]

Waveshare UPS HAT (E) for Raspberry Pi 5/4/3B+ takes four 21700 Lithium batteries, supports USB PD 3.0

UPS HAT E

The Waveshare UPS HAT (E) is a UPS expansion board for Raspberry Pi 5/4B/3B+ that supports four 21700 Lithium batteries and includes a battery fuel gauge IC for monitoring voltage, current, and capacity. The USB Type-C port is compliant with the PD 3.0 standard and allows for 40W fast bi-directional charging, and a high-power buck chip provides a 5V/6A output. Additionally, it supports I2C for real-time status updates. Previously, we wrote about the wider SupTronics Raspberry Pi 5 UPS HAT, which supports four 18650 batteries and delivers up to 5V with a higher current output of 5A. This HAT has no Type-C support and uses a DC jack and XH2.54 connector for 6V-18V input. Feel free to check it out if you’re interested in this product. Waveshare UPS HAT (E) specifications: Compatibility – Raspberry Pi 5 / 4B / 3B+ USB Interfaces USB Type-C Input/Output – Supports multiple voltage levels […]

Waveshare PoE HAT (G) is a compact 25W PoE HAT+ for the Raspberry Pi 5

Waveshare PoE HAT (G)

Waveshare PoE HAT (G) is a compact, easy-to-assemble “mini HAT” designed especially for the Raspberry Pi 5. The most unique thing about this PoE HAT+ is that Waveshare designed it so compact that it could fit in the stock Raspberry Pi case with the cooling fan attached. It supports the IEEE 802.3af/at network standard, delivering up to 5V/5A power output. Other features of the HAT+ include a 40-pin GPIO header, a non-isolated switched-mode power supply, and compatibility with 803.3af/at PoE routers or switches. This makes it ideal for remote monitoring, IoT applications, and networked devices. After the Raspberry Pi 5 was released in the last quarter of 2023, we saw Waveshare launch the PoE HAT (F), which also doubled as a cooling solution and followed the official Raspberry Pi PoE+ HAT introduced in 2021. Both modules are compatible with 802.3at (aka PoE+) and 802.3af standards and support up to 25.5 […]

Raspberry Pi 5 UPS Solution

SunFounder PiPower 3 kit is a UPS solution designed to work with the Raspberry Pi 5, other Arm SBCs, or even MCU boards like Arduino UNO and Raspberry Pi Pico. The board delivers a stable 5V/5A output, and a 32-bit CH32V003 RISC-V microcontroller takes care of power management and battery level reporting to make sure the Raspberry Pi 5 keeps running when a power failure occurs and shutdowns gracefully when the battery level is low. The kit comes with two 18650 2,000mAh batteries that connect through a 2-pin connector, and all accessories – standoffs, acrylic case, and fan – for assembly with the Raspberry Pi 5, or other compatible boards like the Pi 4, Banana Pi BPI-M5, Radxa Rock Pi E, Orange Pi 3B, and others.   PiPower 3 kit specifications: 32-bit CH32V003 RISC-V microcontroller supporting I2C communication Input – 5V/5A via USB Type-C with PD support Output – 5V/5A […]

Matter 1.3 specification adds support for water and energy management, electric vehicle chargers, and various household appliances

Matter 1.3 Specification

The Connectivity Standard Alliance (CSA) has just announced the release of the Matter 1.3 specification and SDK with energy reporting, support for water and energy management devices, electric vehicle chargers, several new “major appliances”, namely various kitchen appliances and laundry dryers, and various other features. As a reminder the Matter protocol was initially introduced several years ago under the name Project CHIP to improve the interoperability of Smart Home devices from various vendors, so for example, users could connect a Matter-compatible Philips Hue light bulb to a Samsung gateway, or a white-brand Matter sensor with Google Home, etc… Matter started to pick last year with several products launched, and Paisit notably reviewed the MINI Extreme Wi-Fi Smart Switch (MINIR4M), the first Matter device from SONOFF, last October. Matter 1.3 adds various new capabilities and devices. Matter 1.3 highlights: Support for Water and Energy Management Devices Energy Management – Matter 1.3 […]

Microchip 8-bit AVR DU family supports secure USB connectivity and 15W power delivery

Microchip DU Family of MCUs

At Embedded World 2024, Microchip announced their new AVR DU family of 8-bit MCUs featuring a full-speed USB 2.0 data interface along with USB-C 15W Power Delivery enabling up to 12Mbps data transfer and charging. They also have features like secure bootloaders and Program and Debug Interface Disable (PDID), which protect your embedded designs. Based on the Harvard architecture, these MCUs can have up to 64 KB of Flash memory, 8 KB of SRAM, and 256 bytes of EEPROM. Their wide operating voltage range of 1.8V to 5.5V makes them suitable for small, space-sensitive devices, power bricks, and rechargeable devices. But one thing to note is that the USB function is only available for VDD above 3.0V and I2C Fm+ (Fast-mode Plus) is only supported for 2.7V and above. I²C Fm+ extends the standard I²C protocol, boosting communication speeds up to 1 MHz while maintaining compatibility with older I²C devices. It’s […]
