MITSUMI
49MHz Band Transmitting-Receiving Module Conforming to FCC
WMF-T12, R10
FEATURES
WMF series small electric wave type transceiver
modules have been developed as a wireless
controller for PC. Since these modules can be
fleely and directly soldered on PC boards, a non-
directional wireless control system can easily be
realized.
