Solid-State Driver Chip

6 In stock
Extra driver chip for your BooBox Flex, FlexMax, or BooBox 8's solid-state outputs.

The Flex 2, FlexMax 2, Flex 206s, and FlexMax 216s models DO NOT need this chip.  These are only for older models sold before 2015.

Solid-state outputs are extremely reliable when used correctly, but they will burn out if they're shorted out or wired wrong. This is the chip that's used inside our original BooBox Flex, FlexMax and BooBox 8's (none of the current models). The chips are mounted in sockets, so the old one can be easily removed and replaced, no soldering necessary.

Did I Blow My Chip?

  • If some or all of your outputs turn on and don't turn off your chip is blown.
  • If none of your outputs turn on yet everything else seems to be working fine, your chip is blown.
  • If you saw smoke and your controller smells funny, your chip is definitely blown.
