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, […]

Particle’s M-series multi-radio devices connect anywhere with WiFi, cellular, NTN satellite, and LoRaWAN connectivity

Particle Industries Inc., an IoT Platform-as-a-Service company, has announced a new line of multi-radio boards and modules that offer multiple connectivity options in a single product. Particle is a complete edge-to-cloud IoT development platform that offers hardware products and software tools for creating IoT solutions. The company’s latest product, the M-series, has a bold tagline: connect anywhere. Although wireless connectivity has come a long way, there is no single wireless technology that works everywhere. Particle’s M-series aims to address that problem by bundling multiple radios – Wi-Fi, cellular, satellite, and LoRaWAN – into one product. Particle is looking to expand from its two primary wireless technologies: Wi-Fi and cellular, and add two more radios, satellite and LoRaWAN, for broader coverage. These two radios will cover devices in areas such as enclosed spaces (boiler rooms, elevator shafts, basements, and mines) and remote locations (methane sensors in oil and gas plants, boats, […]
