9.
Intelligent data control and no any extra programs required
Even for half duplex communication, no any excessive programs required. All RF system
data sending/receiving and other On-the-Fly conversion and control are performed by
HAC-UM transceivers automatically.
10.
Lower power consumption & Sleep function
With +5V power, the receive current is less than 32mA, the transmit current is less than
42mA, and the sleeping current is less than 5
µ
A.
With +3.3V power, the receive current is less than 26mA, the transmit current is less than
36mA, and the sleeping current is less than 5
µ
A.
11.
High reliability, small and light
By using monolithic radio-frequency integrated circuit and single-chip MCU, the
transceivers have less peripheral circuits, high reliability, and low failure rate.
12.
More options of configurable antennas for user different applications.
