3S/12V Select Pads
Create a solder bridge between
TWO PADS ONLY
to select the voltage of the OUTPUT pad.

I2C/UART3/UART4 socket
Use this socket to connect a GPS receiver with I2C MAG and optional BARO sensors to use Cleanflight GPS
features.
IMPORTANT: The
SCL
and
SDA
are
3.3v
signals
5.0v
is also supplied when powering via USB.
IMPORTANT:
5.0v
to
3.3v
logic level converters are
REQUIRED
for
SCL
/
SDA
if your sensors use
5.0v
signals.
IMPORTANT:
3.3v
ONLY signals
for UART3 R3/T3, UART4 can use
5.0v
signals (T4/R4).

RECEIVER port - Molex Picoblade connector
Connect to a receiver using either of the two supplied cables.
FrSky XSR - Use Straight though cable. UART2 for Serial RX, UART5 for SmartPort.
Other Serial RX - Use dupont cable. UART2 for Serial RX, T5/UART5 for Telemetry (Hott/Smartport/etc).
PPM RX - Use dupont cable. RXD/R2/PPM for PPM, TXD/T2/UART2 for Telemetry.
NOTE: There are also header pins and holes for other receivers. UART5 T5 is ONLY on the receiver port.
5.0v
is also supplied when powering via USB.
