VMX-100-SPP Preliminary Datasheet
General Description
The VMX-100-SPP is a 2.4 GHz Bluetooth radio (or modem) that acts as a wireless transceiver.
Integrating the VMX-100-SPP into a device and setting up Bluetooth serial communication
enables that device to send and receive wireless communication to/from other Bluetooth-enabled
devices.
Features
• Small Size: The VMX-100 Wireless Modem has been engineered to be a very small size
- only 1.44" x 1.335".
• Simple Integration: Using VMX-100 Wireless Modems eliminates the need for expensive
RF engineering and development for your product.
• Fast Time to Market: Using the VMX-100 Wireless Modem reduces the time to market
for your wireless product.
• Highly Customizable: VPrf.com gives you the flexibility you need for your specific
application by offering wireless radio customization and integration services.
• Extended Range: VMX-100 Wireless Modems transmit and receive Bluetooth signals up
to 100 meters (328 feet) with embedded antennas.
• Low Power Consumption: Power management becomes easier with the low power
consumption of the VMX-100 Wireless Modem.
Applications
• Consumer Products
• Medical Devices
• Industrial Products
• Handheld Devices
• Military Devices
• Government Applications
