HDigiWorld WL RF Transceiver Module for Arduino + Remote Control Receiver / ARM / MCU 433Mhz ASK (Toy)
Received the parcel, By cons ... the use scope is disastrous! 5cm without antenna. With an antenna of 17 cm and a 12V supply, I spend 2, 3m ... but no more. I use an Arduino with virtualwire bookstore ... Super disappointed!
