The board has the same form factor as the more famous Raspberry Pi (not the same mounting holes) and the same expansion 40-pin header; the OrangePi PC also features an OTG USB port, a microphone and an IR receiver. Indeed, H3 is an impressive chip -- the board only needs DRAM, voltage regulators and connectors; no need for ethernet phy chip, USB hub etc. The OTG micro-USB port can be turned into a serial port, an ethernet port etc through USB gadget support.

The performance is OK for most of applications; but youtube video playing is a little jerky. The audio output can be the HDMI or the 3.5mm jack. The H3 gets a little hot when playing video; still it is impressive not needing a heat sink.
To test it as for code development, I try to build the recent version of KiCad. A number prerequisite packages have to be downloaded. The entire build takes almost 10 hours. The speed of the micro SD card is probably a factor here. It is also close to running out of memory. The build is successful, but this probably is not a platform for serious software development.
While it is not a replacement for a good laptop or desktop, it is certainly good enough for seriously embedded applications. The 40-pin expansion port has 28 signals, 5V, 3.3V and ground. The signals can be GPIOs or 2 I2Cs, 3 UARTs, 1 SPI and 1 PWM.
There is a port of WiringPi call WiringOP that supports the I/O functions of the expansion header.
There is also a port of python package pyA20.
For a more capable 64-bit version, see OrangePi Prime.
