Board Description

Part Name

Vin

Description

This pin can be used as an input or output. As an input, supply 3.6 to 6VDC to power Azufier. When the Azufier is powered via the USB port, this pin will output a voltage of approximately 4.7VDC due to a schottky diode between USB and VIN. When used as an output, the max load on VIN is 500mA.

DIGITAL 0 ~ 13

Digital GPIO pins.
Note that D0 and D1 are used to communicate with BLE module.

ANALOG 0 ~ 5

Analog GPIO pin ( A2 ~ A5 are optional)

SCK,MISO,MOSI,RST

These 4 pins and the two pins beside (Vin, Gnd) will be needed while reinstall bootloader. These pins can be used as Digital GPIO pins also.
SCK : Digital GPIO 15 pin
MISO : Digital GPIO 14 pin
MOSI : Digital GPIO 16 pin

PWR, TX , RX
