1 Set 4ch 40mhz Remote Transmitter & Receiver Board with Antenna

[Frequency]: 40MHZ[fire board operating voltage]: 3V;[receiver board operating voltage]: 4.5v-6v;[Maximum output voltage of the receiving board]: 4 lines, 2 groups, 2 sets, output two voltages, the size is about 2v-3.5v, respectively control one motor forward and reverse, 3V voltage motor can be used.[Features]: The two voltages of the output may have different sizes. When the battery is low, it may be obvious. Therefore, it is recommended to use the small voltage separately for the steering motor. The remote control distance is sufficient when the power is sufficient. , no interference, after connecting the antenna correctly, about 10 meters, the above is for reference only.[Wiring]:(1) The transmitting board: the red line V+ is connected to the positive pole of the power supply, the black line V- is connected to the negative pole of the power supply, and the ANT is connected to the antenna;(2) Receiving board: the black line is connected to the negative pole of the power supply, the red line is connected to the positive pole of the power supply; the yellow line is connected with a blue line to connect one motor (two long wires are connected to the motor 1, and two short wires are connected to the motor 2).colour:OrangeMaterial:Metal + plasticsize:Launch board: 3.8*5.8cmReceiver board: 2.6*4.3cmPackage Contents:1 x 40mhz Transmitter Board1 x 40mhz Receiver Board2 x Antenna2 x Screws with nutsNote:This version of the two-way output is basically the same, suitable for the micro-motor with the blocking current below 2A, and the other 27M board of the store can be used at the same time without interference.Only the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
