Woozi Select-Fire Board

(1 customer review)


Upgrade for the N20 Woozi. Enables fire control for full-auto, 3 round burst, and semi-auto modes by use of signals from switches in the pusher box to tell the board if the pusher is forward or back.

– Designed by Woody7070 and manufactured by Michael Ireland
– Designed specifically for the Woozi, but capable of being used in other builds as well
– If you would rather not solder directly to the board, but want us to pre-solder crimp pins onto the board for a more plug-and-play setup, select that option on the listing
– Warning, this level of soldering and modding is fairly advanced. If you have rough solder joints, short circuits, or loose connections, your board will not function properly and may burn out. The majority of problems we have seen have been loose connections so it doesn’t work, or short circuits so it goes hay wire. Please solder, assemble, and install with extreme care.DEFAULT Listing Includes:
– 1x Select-Fire Board
– 1x Select-Fire Switch
If you select Wiring & Pusherbox Switches, the following will be added to the above:
– 2x 10a Microswitches
– 60″ Thin Gauge Red Wire
– 60″ Thin Gauge Black Wire
If you select “Include 3D Printed Woozi Selector Knob”, the following will be added:
– 1x Woozi Selector Knob

If you have an older Woozi version that does not use an N20 motor for the pusher, you will need to replace nearly all of the prints. You can buy prints from us, or print your own.

    Great addition to the N20 Woozi. 3 round burst is a nice change of pace from 1 second mag dumps! Easy to install.
