GROUND
POWER
Supply ground, be sure to have a well-
grounded connection to avoid noise
over the audio outputs.
6
3.3V
POWER
Main supply voltage: 2.7v-3.5v. Be sure
to use a 10uF and 100nF coupling
capacitors to GND as close as possible
to avoid noise over the audio outputs.
7
Rx - V+
INPUT
Digital input pin RX (asynchronous
serial receiver input pin). Internally
pulled-up to 3.3V via a 40K resistor. 5V
tolerant input.
8
TX - V-
OUT
Digital output pin TX (asynchronous
serial transmitter output pin).
9
R-OUT
OUT
Pre-amplified right channel audio
output pin. Connect this pin instead of
the 3.5mm plug connector, those are
internally connected. (*Do not use
both plug and this pin at the same
time).
10
L-OUT
OUT
Pre-amplified left channel audio
output pin. Connect this pin instead of
the 3.5mm plug connector, those are
internally connected. (*Do not use
both plug and this pin at the same
time).
