The Orange Pi 4 is a single board computer uses the Rockchip RK3399 chip, and has 4GB LPDDR4 memory.

Note that the I2C 1 bus SDA and SCL pins do not reside on pins 3 and 5 like a Raspberry Pi, and so far despite there being multiple active buses (0, 1, 3, 4 and 7), I've been unable to get any I2C device to show up using i2cdetect. Therefore, until there is some resolution of this issue, the Orange Pi is not considered suitable for robotics use. While it is a higher performance board than the Raspberry Pi 4, it also runs very hot, with a power consumption of over 4 watts, whereas the Raspberry Pi 4 is rated 2.85w, the Pi 3 B+ at 2.5w.
