Pironman 5 Pro Max Review – A Raspberry Pi 5 Tower PC case with integrated video and audio capabilities, optional UPS kit

SunFounder has sent us a sample of the Pironman 5 Pro Max tower PC case for Raspberry Pi 5 for review alongside a PiPower 5 UPS board. The “Pro Max” builds upon the Pironman 5 Max we reviewed last year, but adds a 4.3-inch capacitive touchscreen display, a 5MP camera module, two speakers, a USB microphone, and a 3.5mm audio jack. The PiPower 5 is a UPS HAT designed for Raspberry Pi Zero/Model B single board computers, and not directly compatible with the Pironman cases, but we’ll still try to use it. I’ll start this review with an unboxing of the Pironman 5 Pro Max and PiPower 5 packages, followed by an assembly guide for the Pironman 5 Pro Max, a test of the new features (display, camera, audio interaction), and finally, I’ll have a quick test of the UPS HAT with the Raspberry Pi 5 enclosure. Unboxing of Pironman […]

WiQwiic-32 – A compact USB-C IoT board with eight Qwiic connectors (Crowdfunding)

Hack The Board’s WiQwiic-32 is a small USB-C IoT development board based on an ESP32-S3-WROOM-1 Wi-Fi and Bluetooth module, and equipped with a 1.14-inch LCD and eight Qwiic ports for easy prototyping with compatible modules. It also features a microphone and a buzzer for audio interaction, four buttons, two RGB LEDs, and a power LED. There aren’t any through-holes for GPIO pins, so expansion is only possible through the Qwiic connectors, although you can always add a Qwiic to header converter module if you ever need breadboard-compatible GPIO headers. WiQwiic-32 specifications: Wireless Module – ESP32-S3-WROOM-1 SoC – Espressif Systems ESP32-S3 CPU – Dual-core Tensilica LX7 up to 240 MHz with vector extension for AI/ML workloads RAM – 512KB SRAM Storage – TBD Wireless – WiFi 4 and Bluetooth LE 5 Antenna – PCB antenna Display – 1.14-inch TFT display Audio On-board buzzer Built-in microphone for voice and sound detection USB […]

$15 STM32U575 development board features FPC display connector, microSD card slot, two 48-pin GPIO headers

A few days ago, we looked at the WeAct Studio STM32U585CIU6 development board, which features an ultra-low-power STM32U5 Cortex-M33 MCU and was added to MicroPython v1.28. If you’re looking for another STM32U5-based option, especially for compact UI projects, Maker Go now offers an STM32U575 board with a display connector, a microSD card slot, and many more GPIOs While the STM32U585 on the WeAct board features cryptographic accelerators, the STM32U575VGT6 MCU on the Maker Go board is closely related and still offers the same high-performance Cortex-M33 core running at 160 MHz, along with ultra-low-power capabilities. This new board also adds 8MB of external flash and is designed to accept 1.47-inch or 2.0-inch LCDs directly via a ribbon cable. STM32U575VGT6 board specifications: Microcontroller – ST STM32U575VGT6 Core – Arm Cortex-M33 Armv8-M core clocked at up to 160 MHz with FPU, Arm TrustZone Memory – 786 KB SRAM Flash – 1024 KB (1 […]
