Review of Purple Pi OH – A Rockchip RK3566 SBC tested in 2GB/16GB and 4GB/32GB configurations

Review of Purple Pi OH and Purple Pi OH Pro

Hello, I am going to review the Purple Pi OH boards from Wireless-Tag. The Purple Pi OH is a single-board computer (SBC) mechanically compatible with the Raspberry Pi. They are designed for personal mobile Internet devices and AIoT devices, which can be used in various applications, such as tablets, speakers with screens, and lightweight AI applications. The manufacturer sent me two models. The first model is the Purple Pi OH, which is equipped with 2GB of memory and 16GB of storage space and supports 2.4GHz Wi-Fi. The second model is the Purple Pi OH Pro, equipped with 4GB of memory and 32GB of storage space. This board supports both 2.4GHz and 5GHz Wi-Fi. The other components of both devices are almost the same. They are powered by the Rockchip RK3566 chip, which integrates a quad-core Cortex-A55 processor up to 1.8 GHz, a Mali-G52 GPU from Arm for 3D graphics acceleration, […]

Make a Raspberry Pi 5 Game Boy lookalike with the PiBoy DMGx handheld gaming console kit

PiBoy DMGx

Experimental Pi’s PiBoy DMGxis is a kit that converts the Raspberry Pi 5 into a handheld gaming console that looks like a Game Boy with a 3.5-inch color display and all the controls found on the original Game Boy. The company has launched several PiBoy portable game console kits for Raspberry Pi SBCs over the years, so the new PiBoy DMGx for the Raspberry Pi 5 should come as no surprise, and the company says it should be able to run emulators for N64, PSP, Dreamcast, Wii, Gamecube, PS2, and others.   PiBoy DMGx kit specifications: Supported SBCs – Raspberry Pi 5; with adapters: Raspberry Pi 3 and 4 Storage – MicroSD card slot (11) Display – 3.5-inch display with 640 x 480 resolution (3) Video Output – Micro HDMI port from RPi 5 Audio – Speaker (5), 3.5mm audio jack (7) User inputs – D-Pad (10), analog stick (9), […]

Some Raspberry Pi 5 boards can be overclocked up to 3.14 GHz (and run just fine)

Raspberry Pi 5 overclocked 3.14 GHz

The Raspberry Pi 5 is advertised as a single board computer with a CPU clocked up to 2.4 GHz, but some of the boards can run stably at a higher frequency, and Jeff Geerling found out one of his boards could be overclocked up to 3.14 GHz with no issues when running a stress test. The Raspberry Pi 5 already delivers a two to three-times jump in performance against the previous generation Raspberry Pi 4 SBC when clocked at 2.4 GHz, but some already overclocked their up to 3.0 GHz, and many thought it was the maximum limit. But a recent firmware release proved them wrong, as it turns out some Raspberry Pi 5 boards can boot at 3.2 GHz and run stably at 3.14 GHz with an adequate cooling solution. The voltage was also adjusted in the config.txt to more or less safe settings. Contrary to the photo above, […]
