This 15 channel can control 6 small motors forward and reverse
The remote control is equipped with 2 1.5V ordinary batteries (need to be provided),the voltage can not exceed 3V
Receive motherboard voltage:7.2V (small power board) When the input voltage is 7.2V,the output voltage of each group of motors is about 5.4V,Remote frequency:2.4GHZ signal is stable,remote control distance is far
About 2.4GHZ frequency remote control:In theory,2.4GHZ frequency can accommodate up to 400 frequencies,which can be used by multiple people without mutual interference.Simply put,if you buy two or more 2.4GHZ remote frequency frequency toy cars,Play without any interference,this low frequency remote control can not do.Therefore,the 2.4GHZ frequency needs to be paired before use.Even if there are many 2.4GHZ remote control cars around,it will not interfere.
The frequency method:the switch of the remote control switch and the receiving board can be turned on at the same time,or the switch of the receiving board can be opened first and then the switch of the remote control is turned on immediately (1~5 seconds).At this time,the indicator light on the remote controller will flash,that is,automatic
The frequency state,until the flash does not flash,it means the frequency is completed,usually within 10 seconds will be completed; then you can start using it! Pressing the respective buttons will control the corresponding motor to be reversed.
Wiring instructions:The power supply needs to be DC voltage 6V-7.2V,please look for the positive and negative poles of the power supply,not reversed,burn out at your own risk!
