JDY-41 2.4G Wireless Serial Transparent Transceiver Module 160 Meters Line-Of-Sight TTL Serial Port ACK GPIO Control Lea

Specifications Model JDY 41Color GreenWorking frequency band 2 4GTransmission power 12 dbWorking temperature 40℃ to 80℃Reception sensitivity 96 dbTransmission distance 160 metersWorking voltage 2 2V 3 6VTX current 40mARX current 24mASleep current 10uACommunication interface Standard TTL serial portFeatures 1 2 4G long range transparent transmission up to 160 m line of sight each packet uses a checksum to avoid garbled data 2 UART supports transparent and command modes with target addressing and ACK confirmation so the sender can know if data was received 3 Serial commands can drive receiver GPIO pins to high or low levels for switch control 4 Learning remote mode the receiver learns the transmitter s ID and then accepts only that controller supports low power remote use 5 PCB package compatible with JDY 40 but the communication protocol is completely different Package included 1 x JDY 41 Moduleor1 x Antenna
