USB-to-UART bridge via micro USB port
Power LED

Serial Console¶
UART0 is, by default, the serial console. It connects to the on-board CP2102 converter and is available on the USB connector USB CON8 (J1).
It will show up as /dev/ttyUSB[n] where [n] will probably be 0.
Buttons and LEDs¶
Buttons¶
There are two buttons labeled Boot and EN. The EN button is not available to software. It pulls the chip enable line that doubles as a reset line.
The BOOT button is connected to IO0. On reset it is used as a strapping pin to determine whether the chip boots normally or into the serial bootloader. After reset, however, the BOOT button can be used for software input.
LEDs¶
There are several on-board LEDs for that indicate the presence of power and USB activity. None of these are available for use by software.
