Even for half duplex communication, no other excessive programs are required.

All RF system data transmission/reception and other On-the-Fly conversion and

control are performed by KYL-300L transceivers automatically.

10. Lower power consumption & nice sleep function

With +5V power, the receiving current is less than 25mA, the transmitting current

is less than 300mA, and the sleeping current is less than 20uA.

11. High reliability, small size and excellent performance

By using monolithic radio-frequency integrated circuit and single-chip MCU, the

transceivers have less peripheral circuits, high reliability, and low failure rate.

12. Various options for configurable antennas.

13. Watchdog monitor inside

Watchdog monitors the inner operation, so it can change the traditional product

structure and also improve the reliability of our modules.

14. With beautiful metal shell.
