This hardware user manual provides information about the features and signals available on ROCK Pi E board.
Processor
The Rockchip RK3328 Soc used in ROCK Pi E is a high-performance Quad-core Cortex-A53 application processor. It has Neon and FPU coprocessor, shared L2 cache, GPU and so on.
RK3328 Soc can run at 1.3 GHz CPU clock speed.
Networking
On the ROCK Pi E board, the 100M and Gigabit Ethernet port are provided.
For Giga Bit Ethernet, from the test result, we know that the bandwidth is at least 794Mbits/sec. If you are interested in POE (Power Over Ethernet), you should try it on the ROCK Pi E board.
The ROCK Pi E also support WiFi as well as Bluetooth.
Peripherals
The ROCK Pi E has one USB3.0 Type-A connectors.
The ROCK Pi E 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.
The ROCK Pi E is equipped with a standard 3.5mm jack. An audio lead is necessary to produce sound. Audio can be played through speakers or headphones using jack.
TF Card Interface
The TF card can be used as a system storage or an external storage. When it's used as a system storage, you had better choose the ones with storage space larger than 8GB. When it's used as an external storage, you can choose the ones with storage space up to 128GB. When the TF card is inserted into the TF card slot , the device will be automatically recognized by the system.
The TF card interface pin specification shows below.
