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.

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.

  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.
