The Polarstar Universal Plugboard connector board is designed for use in all MG and LMG style airsoft guns, such as the M249. The plugboard is compatible with all PolarStar HPA units, including the Fusion Engine. It can also be used with custom wiring setups when a model-specific circuit board is not available.
The connector board features four 2-pin connector slots and one 5-pin connector. The 5-pin connector is intended for the main wiring. The 2-pin connectors are labeled as follows:
- CON1 = Nozzle solenoid
- CON2 = Poppet solenoid
- CON3 = Selector input
- CON4 = Trigger input
