Compatibility with Raspberry Pi#

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 — at least with Raspberry Pi accessories.

While it is a higher performance board than the Raspberry Pi 4, it also runs very hot (at times upwards of 80°C), with a power consumption of over 4 watts when fully loaded, whereas the Raspberry Pi 4 is rated 2.85w, the Pi 3 B+ at 2.5w. Testing on various websites indicates its actual power usage is probably closer to the Pi 4 when not under load, and in the case of the Orange Pi 4B, not using the NPU (Neural Processing Unit).
