ITEM NAME:1 Set 4CH 40MHZ Remote Transmitter & Receiver Board with Antenna for DIY RC U7G8 1 Set 4CH 40MHZ Remote Transmitter & Receiver Board with Antenna for DIY RC U7G8 [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:Orange Material:Metal + plastic size:Launch board: 3.8*5.8cm Receiver board: 2.6*4.3cm Package Contents: 1 x 40mhz Transmitter Board 1 x 40mhz Receiver Board 2 x Antenna 2 x Screws with nuts Note: 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..[Frequency]: 40MHZ. 1 x 40mhz Transmitter Board. 1 x 40mhz Receiver Board. size:Launch board: 3.8 5.8cm. When the battery is low, it may be obvious. 2 x Antenna. Receiver board: 2.6 4.3cm.
