4CH RC remote control 27MHz/40Mhz circuit PCB transmitter&receiver board for toy car
Dimensions: 3.5 * 7 cm emission plate,
receiver board 2.6 * 4.3 cm;
emission plate voltage: 3-4.5V;
Receive board working voltage: 4.5v-6v;
Received board OUTPUT :4 lines,2v-3.5v
receiving range about 10meter
(A) emission plate: red V+ positive power supply, black wire V- negative power supply, ANT connect the antenna; 3-4.5V
(2) receiver board: black wire = negative power supply, red wire =positive power supply;
L R wire for moter 1 can supply continue powerful supply
F B wire for moter 2 can supply continue power supply
note:only can use small power motor, such as 130 motor,
high power motor can burn the board.
it can control 2 motor go and back
what different between 20Mhz and 40 Mhz?
them are same, only the frequency different, use different frequency, they can play together at same time.
