Using the same proven firmware as the existing Serial Expander but with a heavyweight PCB the High Power Serial Expander provides secure power handling. Tested at 20A continuous and 30A for 30s.


The Serial Expander has 4 servo outputs which can be assigned to any of the channels available in the serial link from the receiver.


The Serial Expander supports the following serial links:


  • SBus – Futaba / FrSky
  • XBus – JR/DFA
  • SRXL – Spektrum
  • ExBus – Jeti
  • P2Bus – PowerBox Core
  • SRXL2 – Spektrum SMART RX


If using PowerBox Core, Jeti, or JR/DFA radios the Serial Expander can be configured from the radio. In XBus mode the Serial Expander looks like a CV4 XBus expander unit (providing mid and end point matching and channel reversing features).
