• Fully surface mount designed

• 4 FET driven outputs (1 PTT and 3 AUX)

• 3 auxiliary outputs (which can be tied to anything, including your coffee maker)

• High impedance COS circuitry

• Settable COS switch point for 1.5 and 3 volt logic

• Higher accuracy DTMF decoder

• Less susceptible to RF interference

• Gives the ability to build a full featured, full duplex repeater controller with remote in software only!

• All options are jumpered, no more diodes to clip

• Full duplex IRLP capable

• Over voltage protection

• Over current protection

• Polarity protection

• On-board power connector

• Pin compatible with version 2.02 boards

• Ships faster. No building time required!
