'''ESC connection'''
−
* When telemetry is not in use, the throttle servo or ESC is connected to the '''[IO2]''' output.
−
* When using a telemetry receiver and an ESC with telemtry data connector, the ESC is connected to the '''[IO1]''' output. The data signal of the ESC is connected to '''[IO2]''' input. (You will get further information about connecting the speed controller and setting up telemetry on the next page!)
−
* You can connect a power supply (second BEC wire, battery) to the [SYS] port and/or to the receiver (in case this has additional servo or battery ports). All servo ports will form a parallel power circuit (except the port [RUD|PIT|AUX]; please do not connect anything here!).<br />

<br /> '''When using a big heli with standard size servos it may be insufficient to only provide power at the [SYS] port or receiver.''' Adding additional power wires is highly recommended! If there are no other ports left to additionally feed in power, we recommend using the MICROBEAST PLUS HD which comes witch an additional high power input. This reduces wiring resistance and serves todays demands for a robust servo power supply.<br />

Single wire with telemetry
Receivers with bidirectional telemetry uplink (Spektrum® SRXL2, Jeti® EXBUS, FRSKY® F.Port2, FUTABA® SBUS2) must be connected to the pin board at the side of MICROBEAST ULTRA. To connect a receiver with standard servo connectors, i.e. the SPEKTRUM® AR6610T, AR8020T or JETI EXBUS receivers, you need an adapter from servo plug to JST-ZH type. We offer a special adapter if needed - order nr. BXA76403. Voltage is the first pin from the left, signal is connected at the third pin from the left. Minus is the second pin from the front/right.
SRXL2 receiver with standard servo connector and adapter
To connect a SRXL2 remote receiver like SPM4650/SPM4651T it is necessary to INTERCHANGE THE WIRES of the supplied 4-pin receiver connector. In this configuration you can directly plug in the receiver without the need for an extra adapter. But be very careful! Make sure plus and minus are placed properly! The signal wire is connected at the fourth pin from the front/right, minus ist second pin from the front/right, voltage (+3.3V) is the first pin from the front/right. On satellite side the signal output is on the outer side, the pin next to it is not used, then we have voltage and on the inner side comes minus.

Modified 4-pin SRXL connector
Never connect the 4-pin receiver connector to MICROBEAST ULTRA without modification and in wrong polarity! This will damage your receiver immediately! Check polarity at least twice before connecting the receiver to MICROBEAST ULTRA . It is up to you to make sure polarity is correct. We do not assume any liability in case you do it wrong.
