ROCK Pi 4C+
by Radxa Limited
ROCK Pi 4 Model C+ is a single board computer (SBC) by a Rockchip RK3399-T hexa-core processor @ 1.5 GHz, equipped with 4GB RAM, and two micro HDMI ports to drive up to one 4K display, and one 2K display.
ROCK Pi 4 Model C+ support dual HDMI output, Micro HDMI 2.0 port up to 4K @ 60 Hz; Micro HDMI 2.0 port up to 2K @ 60 Hz; 4-lane MIPI DSI via FPC connector (only 2 lanes if the SPI flash is soldered to the board); Dual independent display support (not three before the 2K HDMI and MIPI DSI interfaces are multiplexed)
ROCK Pi 4 Model C+ including a 40-pin GPIO interface ,and also features a Gbit LAN for 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 Bluetooh 5.0, ROCK Pi benefits improved Bluetooth speed and greater range.
ROCK Pi 4 Model C+ provides support for Debian/Ubuntu Linux, Android 7.1/9.0/11 for the board, with open-source GPU drivers (that should be Panfrost), as well as hardware access/control library for Linux/Android. All RK3399/OP1 processors are software compatible

Adafruit Blinka Installation
We use a special library called adafruit_blinka (named after Blinka, the CircuitPython mascot) to provide the layer that translates the CircuitPython hardware API to whatever library the Linux board provides.
For example, on Raspberry Pi we use the python RPi.GPIO library. For any I2C interfacing we'll use ioctl messages to the /dev/i2c device. For SPI we'll use the spidev python library, etc. These details don't matter so much because they all happen underneath the adafruit_blinka layer.
