4CH RC remote control 27MHz/40Mhz circuit PCB transmitter&receiver board for toy car
SKU: SNRM12/SNRM13
Dimensions: 3.5 * 7 cm emission plate,
receiver board 2.6 * 4.3 cm;
Frequency: 27MHZ/40Mhz
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
Connection method:
(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 motor 1 can supply continue powerful supply
F B wire for motor 2 can supply continuous power supply
Note:
note:only can use small power motor, such as 130 motors,
high power motor can burn the board.
it can control 2 motors go and back
…………..
what different between 20Mhz and 40 Mhz?

These are great for fitting into smaller models for ships or planes propellers, tank tracks or turrets ,even cars. Inexpensive & easy to wire up. Great for those to start learning about wiring as very inexpensive to practice with.
