NanoPi A64 is A64 based development board produced by FriendlyARM. It comes with onboard gigabit Ethernet, 802.11 b/g/n WiFi, HDMI, and two USB A ports.
There is a label on top of the Ethernet port with a QR code and "NanoPi-A64" written on it. Also on the SoC there is a quite prominent "A64" print.
On the back of the device, the following is printed:
The PCB has the following silkscreened on it:
From the software point of view this device is similar to the Pine64 (similar DRAM, same Ethernet and PMIC), so basic support should work with some Pine64 image if PMIC configuration is identical (at least according to this review Pine64 images don't even boot).
FriendlyARM provides an adopted BSP on Github
You can build things for yourself by following our Manual build howto and by choosing from the configurations available below.
Use the nanopi_a64_defconfig build target (supported since v2017.09).
Use the sun50i-a64-nanopi-a64.dtb device-tree binary.
Tips, Tricks, Caveats
There is no FEL button on this board. Booting without an SD card automagically enters FEL mode.
A64's USB OTG port is exposed as Type A receptacle and the Micro USB jack is for powering only (exactly identical with Pine64).
Powering the board
A battery connector has been saved so the only way to power the board is with 5V through GPIO headers (either 40 pin or the 4 pin debug header) or the Micro USB jack. In case you use the latter please keep in mind that a lot of stability/boot problems are related to Micro USB being the wrong choice for DC-IN. At least the Micro USB cable FriendlyARM ships with the device is of good quality (low resistance).
ESD & over-current protections
Based on the schematic Rev 1610 (December 15, 2016) the board incorporates the following protections:
x - no protection, ESD - Electrostatic Discharge, OC - Over-current
|1||USB micro (power)||x||x||Power supply bypass.|
|6||Dual USB||ESD||x||Power supply bypass.|
|8||Ethernet||x||N/A||Over-current protection is not applicable.|
|9||GPIO||x||x||Only UART2 & UART3 have ESD protection.|
|10||Debug UART||ESD||OC||Current is limited by using resistors.|
|11||Audio jack||ESD||N/A||Output current is internally limited by SoC.|
Serial port / UART
The board exposes 2 UART ports trough the GPIO header and the UART0 port on a separate 4 pin header
UART2 uses pins 11 (TX), 22 (RX) and UART3 uses pins 8 (TX), 10 (RX).
All of the UARTs use 3.3V voltage levels. Look at our UART howto for further instructions.
Locating the UART
Below the GPIO there is a separate 4 pin header with "DBG_UART" silkscreened next to it, in the bottom of the board the labels "RX", "TX", "5V", "GND" can be found next to the corresponding pins.
