Radxa RS117-D4 Rock 3 A 4 GB 4 x 20 GHz
ROCK 3A is an improved version of ROCK Pi 4 with some performance improvements and additional new interfaces.The Rock 3A is based on the RK3568 chip. This allows more input and output possibilities. In addition to an M.2 Key M port for connecting an NVMe SSD with two PCIe 3.0 lanes, an M.2 Key E port connected via a single PCIe 2.0 lane is also available. This can also be addressed via UART, but also supports WiFi 6 cards for a particularly fast, wireless connection to a network.The built-in RK3568 has four Cortex A55 cores, with clock speeds of up to two gigahertz. Plus a Mali G52 graphics solution. In addition to the NVMe SSD, an eMMC module or a classic microSD card can be used to store the operating system, applications and data. A Gigabit Ethernet port with PoE support is available for network connection.Image signals can be transmitted via the HDMI 2.0 port, plus a MIPI DSI connector. A 3.5 mm jack plug allows the easy connection of headsets or loudspeakers. External accessories and also external memory can be connected via two USB 2.0 and USB 3.0 ports each. A battery-operated real-time clock is available on the 85 x 54 mm large developer board. The 40-pin GPIO pin header is color-coded and is mostly compatible with the Raspberry Pi and the Rock Pi 4.Debian 10 is also supported on the software page.Specification:- SoC - RK3568- CPU â Quad A55 to 2GHz- GPU - MALI G52 GPU, 0.8T NPU- Operating system: Android 11.0, Debian 10 / Ubuntu / Slackware- Plug-in eMMC module, 2/4/8GB LPDDR4 3200MT/s, DRAM controller frequency up to 1560MHz- QC/PD performance support with a new generation QC/PD protocol IC- two USB2.0 two USB3.0 (1x OTG+1x HOST), the two USB3.0 can be configured in SATA mode with a SATA breakout cable- GbE with PoE support- M.2 M-Key for NVMe with PCIe 3.0 x2 lanes- M.2 E-Key for connectivity with PCIe 2.0 x1/SDIO/UART, supports Wi-Fi 6 cards- 1x MIPI DSI, 1x MIPI CSI, compatible with ROCK Pi 4- 40P GPIO header, mostly compatible with ROCK Pi 4This text is machine translated.
