Module Category Details
Power Supply:
The WDAM1 module has a 3.3V (800mA max current) voltage regulator located onboard. It has a maximum dropout
voltage of 1.3V. Each header has Vin and 3.3V pins. The Vin pins are internally connected and functionally equivalent.
The 3.3V pins are both outputs and are also internally connected. Having the same power pins on each header allows for
more motherboard layout options. When using the internal regulator: Supply a minimum of 4.75V to either header’s Vin
pin. The 3.3V pins can be used to power external devices such as a SRC or DAC/ADC.

Digital IO:
WDAM1 has general purpose digital IO (“GPIO”) pins available that are configured in the application firmware. GPIO pins
use the 3.3V logic voltage and have the following software configurable features: IO direction, drive strength (for output
only), Schmitt Trigger (for input only), pull up (input only), pull down (input only), slew rate (output only). WDAM1 is also
capable of active-high and active-low configuration of LEDs.

RF
:
WDAM1 modules utilize a PCB trace antenna in an inverted F configuration. This provides a typical indoor range
of 20 meters or more (dependent on the number and construction of walls and/or ceilings).

Audio:
WDAM1 is capable of streaming digital audio using the I2S protocol. GPIO can be allocated for configurable Digital-
Audio pins (e.g. for AMP / DAC enable, Mute, etc.) and also as I2S protocol pins (e.g. Bit Clock, LR Clock, Master
Clock and Data).
