| − | The ROCK Pi 4 is the lasted SBC released by radxa.
| + | |
| − | | + | |
| − | == Processor ==
| + | |
| − | The Rockchip RK3399 Soc used in ROCK Pi 4 includes 64bits hexa core processor with dual 1.8GHz Cortex-72 and qual 1.4GHz Cortex-A53, Mali T860MP4 graphics processing unit (GPU) and Internal SRAM. It has a level 1 (L1) cache and a level 2 (L2). For level 1 cache, 48KB Icache and 32KB Dcache is for each A72. 32KB Icache and 32KB Dcache is for each A53. For level 2 cache, 1024KB cache is for big cluster and 512KB cache is for little cluster.

| − | == Networking ==
| + | |
| − | On the ROCK Pi 4 Model A, B board, the Giga Bit Ethernet port is provided. From the test result, we know that the bandwidth is at least 939Mbits/sec. If you are interested in POE (Power Over Ethernet), you should try it on the Pi 4 board.
| + | |
| − | <br />The ROCK Pi 4 Model B is equipped with 2.4GHz 802.11 b/g/n and 5G ac/a WIFI. The Pi 4B also features Bluetooth 5.0.
| + | |
| − | | + | |
| − | == Peripherals ==
| + | |
| − | The ROCK Pi 4 Model A and B have four USB-A connectors. One is for USB 3.0 OTG. One is for 3.0 HOST. And the others are for USB 2.0 HOST. The hardware switch for host/device switch may be useful when you use the USB 3.0 OTG connector. The ROCK Pi 4 may be operated with any generic USB computer keyboard and mouse. It may also be used with USB storage, USB to MIDI converters, and virtually any other device/component with USB capabilities.
| + | |
| − | <br />（need USB hub picture）
| + | |
| − | <br /><br />
| + | |
| − | The ROCK Pi 4 Model A and B are equipped with a standard 3.5mm jack. An audio lead is necessary to produce sound when there is not an HDMI cable. Audio can be played through speakers or headphones using jack. This requires you to use the Desktop volume control for configuration.
| + | |
| − | <br />(need jack picture)
| + | |
| − | <br /><br />
| + | |
| − | The ROCK Pi 4 Model A and B feature an MicroSDHC card slot. When you running your system using eMMC Module, you can definitely use an up to 128GB uSD card as your storage.
| + | |
| − | <br />(need uSD sloot picture)
| + | |
| − | <br /><br />
| + | |
| − | On ROCK Pi 4 Model A and B board, M.2 connector supports up to 2T M2 NVME SSD.
| + | |
| − | <br />(need M.2 slot picture)
| + | |
| − | <br /><br />
| + | |
| − | There is a wide range of camera applications in our lives. MIPI CSI 2 lane on board support 800 MP camera via FPC connector.
| + | |
| − | <br />(need MIPI CSI picture)
| + | |
| − | <br /><br />

| − | == General purpose input-output (GPIO) connector ==
| + | |
| − | | + | |
| − | ROCK Pi 4 has a 40-pin expansion header. Each pin is distinguished by color.
