Shipping
We are an online wholesale platform and shipping costs are charged separately for greater benefit to you.
Air freight costs are based on the weight of the product (including packaging bags and cushioning materials). For products under 2kg, freight is calculated in 50g increments. For products between 2kg and 4kg, freight is calculated in 100g increments. For products over 4kg, freight is calculated in 1kg increments.
If your order exceeds 4kg or the shipping cost exceeds $70, we recommend contacting our customer service for an accurate shipping quote. You will need to provide your zip code address when you contact us.
Air freight options include DHL, UPS, FedEx, and Yun Express, with a delivery time of 7-12 days.
When the weight of the express delivery exceeds 12kg or air shipping cost exceeds US$100 or sea shipping cost exceeds US$50, you can choose B2B shipping:
Air freight(10-14 days)
Yun quik boat sea freight (15-20 days)
Quik boat sea freight(20-25 days).

The DY-41 is developed using 2.4G technology, with a line-of-sight range of 160 meters. It features serial port pass-through, switch control, low-power remote control, and a learning remote control. It's important to note that the JDY-41 and JDY-40 are only compatible in terms of PCB package; their communication protocols are completely different. The JDY-41's long-distance pass-through communication ensures that every data packet is checked, preventing the receiver from receiving garbled data. Significant improvements have been made in communication distance; in actual testing, it achieved a 160-meter pass-through distance without packet loss. It supports serial port commands to control the high and low levels of the receiver's GPIO pins, and serial communication supports pass-through. Serial communication, including command serial communication and transparent serial communication, means that the sending and receiving serial communication is unformatted. The transmitter sends whatever data is sent, and the receiver receives all the data input from the transmitter's serial port. Command serial communication supports adding a target address to the data to specify the device. Transparent communication supports ACK (acknowledgment) communication; the transmitter transparently transmits data to the receiver, allowing the transmitter to know whether the receiver has received it. Learning remote controls allow the receiver to learn the transmitter's ID code; after successful learning, the remote control receiver will only accept the specified remote control commands.
Application Scenarios
2.1: 2.4G Remote Control
