AQEX qUPS-P-BC-2.0 UPS HAT works with large capacity, multi-chemistry batteries (Li-Ion, LiFePO4, Sodium-Ion)

AQEX qUPS P BC 2.0 multi chemistry UPS HAT

Developed by Hungary-based AQEX, qUPS-P-BC-2.0 is a Raspberry Pi-compatible UPS HAT that supports multi-chemistry batteries, including Li-Ion, LiFePO₄, Sodium-Ion, and even supports large, high-capacity packs up to 300Ah. It is designed for applications that require long backup times and reliable 5V power. It features an offline UPS-like architecture with a highly efficient boost converter, adjustable input voltage and energy thresholds, as well as AUTO/ON/OFF operating modes to prevent reboot loops or unsafe restarts. Communication with the Raspberry Pi is handled through three GPIO pins to provide alerts for power loss and low battery. The board supports up to 7.5A discharge, 2A charging, USB-C and auxiliary 6–28V input, reverse-polarity and thermal protection, and external power-control capability. It’s also stackable with other HATs thanks to a robust soldered 40-pin header. AQEX qUPS-P-BC-2.0 specifications: Compatibility – Raspberry Pi 5 / 4B / 3B+ and other boards with compatible form factor and 40-pin PIO header […]

ESP32-C6-Devkit-Lipo – A small, open-source hardware ESP32-C6 board with battery support, UEXT connector

Olimex ESP32-C6-Devkit-Lipo

Olimex ESP32-C6-DevKit-Lipo board is a small open-source hardware board based on the ESP32-C6 WiFi 6, Bluetooth 5.0 LE, and Zigbee/Thread SoC with support for LiPo batteries and UEXT expansion modules. It’s the second announcement from the company this week, and comes after they introduced the MOD-ESP32-C5 to add wireless connectivity to boards equipped with a UEXT connector. The ESP32-C6-DevKit-Lipo adds to the list of small ESP32-C6 USB-C boards, such as the 01Space ESP32-C6 board and Seeed Studio XIAO ESP32C6, among many others. It’s actually larger than most similar boards, but differentiates itself with its open-hardware design, dual USB-C design, breadboard compatibility, LiPo battery circuitry, and a UEXT connector. ESP32-C6-Devkit-Lipo specifications: Wireless module – ESP32-C6-WROOM-1-N4 module Espressif Systems ESP32-C6 SoC CPU – Single-core 32-bit RISC-V processor @ 160 MHz Memory – 512KB SRAM, 16KB low-power SRAM Wireless 2.4 GHz WiFi 6 1T1R with Target Wake Time (TWT) support Bluetooth LE 5.0 […]

ExtrudeX machine recycles failed/old 3D prints into new filament (Crowdfunding)

ExtrudeX machine recycle 3d printer filament

When 3D printing, users will always waste filament one way or the other, either due to a failed print or because of the support for the print, and there may also be test/old prints that you don’t need/use anymore, for example, a retraction cube or a benchy. That means all that material usually ends up in the dustbin. Priyank Pal, founder of Creative3dp, did not like all that waste, so he created the ExtrudeX machine to recycle 3D print waste and filament scraps back into usable filament. On top of that, the machine itself is 3D printable and much more affordable than commercial solutions from companies such as Filabot. I’d usually provide the specifications here, but as a crowdfunded project, the ExtrudeX’s full technical details are not fully available. We just know that a single DC gear motor drives the main screw inside a metal barrel, while band heaters and […]

Mini review of JOYROOM PODIX 140W 5-port USB GaN charger with power meter function

JOYROOM PODIX 140W 5 port charger review

I’ve just received a review sample of the JOYROOM PODIX 140W 5-port USB GaN charger, which I found interesting because it integrates a power meter function for the whole charger and for each individual port, which could be useful for reviews of USB-powered boards and devices. In this short review, I’ll go through an unboxing, before testing the features with a smartphone, and trying to stress it a little with five devices, including a laptop, a USB-C powered HDMI display, a wireless display, an Android smartphone, and a Raspberry Pi 5 SBC. JOYROOM PODIX 140W charger unboxing I received the device in its retail package, reading “JOYROOM PODIX” “140W 5-port desktop GaN charger” and listing key features like fast charging, 80cm retractable cables, and a 1.54-inch “ultra large” display, as well as compatibility with standards such as USB PD 3.1, PPS, AFC, SCP, FCP, and QC 3.0.
