Specification
Operating Voltage: DC 7.4V (no charging function); includes built-in DC 5V step-down power supply for servos
Operating Current: Must remain below 2A; peak 3A (does not support any high-torque motors)
Compatible Motors: Supports standard motors up to 280 size. Note: Does not support hollow-cup motors, high-speed motors, or high-torque motors
Compatible Servos: Must use 180°, SG90, MG90S, or MG995 servos 360° servos are not supported. Servo control method: The four buttons for Motors 3 and 4 on the remote control module control Servos 1 and 2 to rotate 38° left and right, respectively. When a button is pressed, the corresponding servo rotates 38°; when released, it automatically returns to zero.
Note: Motors 3 and 4 share control with Servos 1 and 2. When the motors are activated, the servos will rotate simultaneously. Select the appropriate mode based on your needs. This product does not include a voltage-reduction function; do not operate it beyond the rated voltage, as this may damage the servos.
Pairing Method: Pair one-to-one; multiple sets can be used without interference or frequency overlap.
Control Range: Approximately 50 meters in open areas.

Mode Switching
Remote Control Module: Insert the batteries correctly, turn on the power, and hold down Switch 4 and Switch 1 for 5 seconds. After the light turns on, briefly press Switch 2 once. The light will flash several times to indicate the current mode. Once you have selected the desired mode, release Switch 4 and Switch 1.
Receiver Module: Insert the batteries correctly. Connect to the motor or servo. After successfully pairing with the remote control module, pressing a button on the remote control module will cause the corresponding motor or servo to perform the corresponding action.

Regarding Remote Control Range:
This module features a built-in 2.4 GHz antenna that cannot be modified. The tested range is approximately 50 meters in open land areas and about 30 meters underwater. As this is a DIY accessory, the installation method is unpredictable, so the remote control range is not guaranteed. Please be aware of this. Ensure there are no objects around the antenna that could cause signal interferences, such as batteries or various metal objects. Also, do not place the module inside a metal enclosure, as this will severely interfere with signal transmission.

Important Notes
Please read the product specifications and features carefully to confirm suitability before placing an order. If you are unsure about the motor specifications, do not attempt to test it, as excessive motor power exceeding the receiver board’s load capacity may damage the circuit board. Before charging, please verify that the battery’s positive and negative terminals are correctly oriented. For 3.7V lithium batteries, ensure they function properly before charging. Otherwise, inserting the battery backwards and attempting to charge it will burn out the module—please be extremely careful!!!
