ROCK Pi 4 Model A 1GB

What is ROCK Pi
ROCK PI is a Single Board Computer (SBC) in an ultra-small form factor that offers class-leading performance while leveraging outstanding mechanical compatibility. The ROCK PI offers makers, IoT enthusiasts, hobbyists, PC DIY enthusiasts and others a reliable and extremely capable platform for building and tinkering their ideas into reality.
ROCK Pi 4 is a Rockchip RK3399 based SBC(Single Board Computer) by Radxa. It can run android or some Linux distributions. ROCK Pi 4 features a six-core ARM processor, 64bit dual channel 3200Mb/s LPDDR4, up to 4K@60 HDMI, MIPI DSI, MIPI CSI, 3.5mm jack with mic, 802.11 ac WIFI, Bluetooth 5.0, USB Port, GbE LAN, 40-pin color expansion header, RTC. Also, ROCK Pi 4 supports USB PD and QC powering.
Class-Leading Performance
ROCK Pi has a modern and powerful hexa-core ARM-based processor, RK3399 inside, it offers significantly improved performance versus other popular SBC boards. All models are equipped with LPDDR4 3200Mb/s RAM and optional high-performance eMMC modules, boost all applications.
Maker Friendly, IoT Connectivity
ROCK Pi features maker friendly expansion options, including a 40-pin GPIO interface that allow for interfacing with range inputs from buttons, switches, sensors, LEDs, and much more. ROCK Pi also features a Gbit LAN for the network, with dedicated bus and controller, it works without latency under heavy load network applications. On board 802.11 ac wifi offers 2.4G&5G WLAN connectivity. With Bluetooth 5.0, ROCK Pi benefits-improved Bluetooth speed and greater range. ROCK Pi also features one USB 3.0 host and one USB 3.0 OTG ports, each 5Gbps/s, working independently. The USB 3.0 OTG can work as a USB device such as Android ADB or USB gadgets. A hardware switch is provided for OTG mode switch.
AI Capabilities
ROCK Pi supports mainstream AI stack with GPU acceleration. Furthermore, a dedicated hardware NPU accelerator coming up next for ROCK Pi will boosts complex Machine Learning algorithm and reduce the power. Industrial standard MIPI CSI connector makes it easy to connect existing cameras to ROCK Pi and ROCK Pi also supports industrial standard MIPI DSI for LCD and touch screen. With the hardware-accelerated algorithm, its great for Computer Vision application, Robotics and much more
