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

Features :

• - Supply voltage: 1.8 ~ 3.6VDC
  (Note: a voltage higher than 3.6 V will cause permanent damage to the module)
  - Communication level: 0.7VDC ~ 3.6V (VCC refers to the module supply voltage)
  - Working frequency: 425M ~ 525MHz (via software setting, the module uses 30M glass)
