[Introduction]：E34-2G4H20D is a 2.4G wireless transceiver module with high speed and long distance(can be transmitter and receiver both). The module features FEC (Forward Error Correction)algorithm.It can correct the interfered data packets automatically, so that the anti-interference ability improved.
