The above launching board uses a 1-meter-long flexible wire for launching. The reference launch distance is about 50 to 100 meters in an open area. Supporting paper circuit schematic diagram and instruction manual, there is no electronic version, the BH1415F version only has the schematic diagram of the emission part, and does not provide the schematic diagram and source program of the control part. Deliver a one-meter-long flexible wire antenna.
The following is the supporting circuit schematic diagram and the thumbnail of the installation diagram. The actual delivery is paper, which is clearer:
Note: This price does not include power supply, housing and Q9 rod antenna!
If you want to install it into a finished machine, you can also purchase the following matching power supplies, shells and Q9 rod antennas:

The above transmission distance is for reference only, not the basic indicator of the transmitter. The transmission distance is affected by many factors, such as what antenna is used for transmission, the height of the transmitting antenna, the surrounding obstacles, the sensitivity of the receiver, the weather, etc., which will cause great discrepancies, and the actual usage and working environment of each customer Different, it is recommended to measure. If you are not satisfied after receiving the goods, please do not confirm the receipt of the goods, please negotiate and solve them in a friendly manner. Thank you for your cooperation!
