The WHM900™ is a low-cost wireless modem module that operates in the license-free 900 MHz ISM frequency band range. The WHM900™ transfers data up to 1,000 feet with proper antenna. Its small size, user friendly AT Command support and other unique features, such as low power consumption and Serial TTL interface, make the WHM900™ ideal for OEM and VAR integration for high performance RF data communications. The WHM900™ is a FCC Part 15.247 / 15.249 approved RF module and requires no additional FCC approvals.
Features:
Industrial -40oC to +85oC operating temperature
Long range – 300 to 500 feet with standard antenna
256 user selectable channels
32 user selectable frequency setting or full range frequency hopping
On board NVRAM for storable configuration
Low power consumption – 36mA / 28mA (TX/RX), 16mA idle mode
Power down mode with only 4 mA power consumption
AT command support
Standard Serial TTL level compatible interface
Small size – 1.0” x 1.0” x 0.3” (excluding antenna connector)
Addressing for point-to-point and point-to-multi point applications
Host interface baud rates from 300 bps to 19.2K, plus 57.6K
Up to 76Kbps over-the-air data rate
Supports hardware (RTS/CTS) and software (Xon/Xoff) flow control
Auto link option for unattended operation
