Description
Description
Pair of 2-way audio communicator boxes
Microphone module: MAX9814
Supports audio amplifier modules: PAM8403, HXJ8002, 5128.
Power socket holder: 18650
Theoretic distance (on 65 Ohm/kilometer cord resistence) - up to 2 kilometers. Then reconnect a jumper "Gain" on MAX9814 from "Power" to "Gnd" - so the signal level will be increased from 40 db to 80 db
