Tips, Tricks, Caveats

FEL mode

When the on-board flash is empty, just remove the MicroSD to enter FEL mode.

Adding a serial port

Locating the UART

The pins tagged "I2C1" on the board is the UART0 (muxed with I2C1).

When seeing from top and have the "SUNXI" silkscreen at left side, the TX pin is the left (12th pin at the bottom), and the RX is the right (13th pin).

Pictures

Note: the yellow wire seen on the back image of the sample board is because this board is one of the earliest samples, and the factory made a mistake when soldering the DCDC chip, which needs to be fixed.
