Mini Tip Controller

Mini Tip Controller


Pyrotechnic ignition board for e-match based electronic ignition pyrotechnics. Two sequential output channels driven from RX servo output or serial bus (SBus, EXBus, DSMX sat, XBus). Glitch proof and start / fail safe protected. Ability to generate 1 servo output if using serial bus.




  • RX Power driven
  • Overload / short protected
  • 1-3S Lipo powered 
  • Single channel PWM input / Serial Bus channel selection
  • Safe start - will not fire on power up regardless of switch position
  • Safe fire - will only fire with correct toggle sequence
  • Sure fire - pulsed output to ensure ignition of e-match
  • 2A per channel peak drive  
  • 24MHz 32bit MCU




Built with safety in mind the 2 channel mini tip controller is designed for standard pyrotechnic e-match ignition (500mA 'all-fire' specification, not talon igniters). The board is powered through the RX connection and is current limited to protect the output FETS and RX power. 1S lipo operation is possible and DSMX sat micro version available to order.

Three separate algorithms ensure safe and reliable operation:

  • Safe start - the board will isolate the outputs and not initialise until it sees a valid signal indicating an 'off' position. 
  • Safe fire - the channel must go high for at least 500mS but not longer than 1500mS to fire the output
  • Sure fire - when a valid trigger is seen the appropriate output is pulsed twice, on for 250mS each time. This ensures ignition of the e-match without risk of post fire short circuits at the match head.

The system uses a sequential fire logic, each toggle advancing to the next output: P1 - P2

Shipped with PWM servo input as default setting. User selectable for various serial bus protocols:

  • SBus
  • ExBus
  • XBus
  • DSMX satellite

Option to provide a single servo drive if using serial bus interface (intended for wingtip streamer release type applications)



The input (standard male servo connector) should be connected to the appropriate RX channel output if using PWM or to the serial bus output if using a serial protocol. In both cases the power for the board and the pyro ignition will be taken from the RX. the peak current draw of the board when firing a pair of e-matches is less than a typical 10Kg servo.

The output (standard female servo connector) should be wired to the ematches with a custom harness - the specific harness will depend on placement of the pyros etc.

Please note that the output, although using a standard servo connector for ease of use, must not be connected to a servo or other RC device.

The output wiring is as follows:


Black Common for both e-matches
Red Pyro channel 1
Yellow Pyro channel 2




Protocol and channel selection is performed using the push button on the board. The mechanism is similar to ESC programming and uses the LED to indicate current settings / values.

Holding the button on power up will enter the programming menu after 2 seconds (fast led flashing).

Red flashes indicate the parameter to be adjusted, green flashes (and orange) indicate the parameter value.

The mini tip controller supports the following three parameters:

  • Protocol (1 red flash)
  • Pyro channel (2 red flashes)
  • Servo channel (3 red flashes)

 A brief press of the button after the desired parameter has been indicated will enter the value setting mode.

The value is indicated by green or orange flashes, a brief press will advance the value, a long press (2 seconds until led flashes quickly) will store the value and return to the previous menu. The value indicated is specific to the parameter being adjusted.



Protocol values:

  • Servo PWM input
  • JR XBus input
  • Futaba SBus input (system expects inverted style input as per Futaba specifications)
  • DSMX satellite input
  • Jeti EXBus input

Note that with DSMX satellite protocol selected a short press of the button at power up will cause the connected satellite to enter bind mode. Be aware that you cannot bind a satellite and a 'park flyer' rx to the same model (full range receivers can be bound with additional satellites).


Pyro Channel values:

To assist with counting higher values the channel number is displayed as a combination of short and long flashes. A long flash indicates 5 a short flash indicates 1, so a sequence of long, long, short would indicate channel 11. For DSMX protocol green flashes indicate main channels, orange flashes indicate XPort channels.


Servo Channel values:

This is identical to the pyro channel value operation.



Available as DSMX only version for 1S lipo. Connects directly to satellite and provides screw connector for e-matches. JST or UM connector available.
