Ujjdwiurgh 1 Set 4CH 40MHZ Remote Transmitter & Receiver Board with Antenna for DIY RC Car Robot Remote Control Toy Parts

[Frequency]: 40MHZ [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. [fire board operating voltage]: 3V; [receiver board operating voltage]: 4.5v-6v; [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., Manufacturer: I286412
