Introduction :
Wireless Module Serial UART (1000M Range-433 Mhz) module is a low-power and high range wireless communication solution that is ideal for Smart home automation, smart lighting, industrial sensor data acquisition and remote control applications.
The module also includes a microcontroller with preprogrammed firmware that provides seamless connection via a TTL serial UART interface.
Transceiver based on the SI4432 Silicon Labs chip
Industry standard model
Capacitive components manufactured by Murata with 10ppm high precision glass
Outdoors - a distance of up to 1 km
