The CPU is a H2 Quad-core Cortex-A7 H.265/HEVC 1080P.
The H2+ SoC is featureless H3 (no Gbit Ethernet MAC and no 4K HDMI output).
see Hardware-GPIO
The SPI-NOR flash is located on the bottom side (see homepage). According to http://linux-sunxi.org/Orange_Pi_Zero the size of the flash is 16 Mbit (2 MByte)
It seems per default the spi-nor is not enabled in the Armbian.
The content of the flash can be written with the "sunxi-fel" tool.
LED is like a special GPIO. see Hardware-GPIO
The schematic indicates the power supply must provide 5VDC, 2A. The schematic indicates that the power tree uses following voltage regulators :
| Module | Regulator | Spec |
|---|---|---|
| AVCC/RTC | SY8008B | 3.3V/300mA |
| DRAM | SY8008B | 1.5V/1A |
| SYSTEM | SY8089A | 1.2V/2A |
| VCC-CPUX | SY8113B | 1.3V/3A |
| VCC-IO | SY8008B | 3.3V/0.8A |
| VCC-WIFI | PST73133BETV | 3.3V/0.8A |
From hardware point of view exits following options :
-
USB micro
In general USB does not provide 2 A. All kind of troubles - more details see http://linux-sunxi.org/Powering_the_boards_and_accessories#Power_connectors
-
Expansion Port pin headers
- pin 2 and 4: +5VDC
- pin 6 : Ground
http://linux-sunxi.org/Xunlong_Orange_Pi_Zero#Expansion_Port
-
Power over Ethernet (Per default disabled)
In short requires soldering, implements only passive mode and is incompatible to the standard i.e. the Orange Pi Zero does not work with switches implementing PoE/PoE+
