XBee is good; Synapse is just better. More I/O, embedded python, and generally better range at comparable cost! This particular module is 2.4GHz with OTA (Over-The-Air) speeds up to 2Mbps, maximum 2.5miles (~4km) range and a F-type PCB for compact installation.
No doubt about XBee - proven, solid and robust. But Synapse modules are that much better! These small, low-power transceiver modules, commonly run in the 915MHz & 2.4GHz spectrums, have a maximum extended range of up to three miles LOS (Line-Of-Sight) and the lowest power consumption in the industry. These RF Engines come pre-loaded with the SNAP® network operating system which allows the nodes to be natively mesh networked. Typical applications include wireless serial port(s), sensor monitoring, actuator control, or an intelligent embedded controller - the possibilities are limitless. Synapse takes 802.15.4 Zigbee/XBee style communication one step further, and makes it smart.
This particular RF module includes a user programmable (via python-based scripts), embedded ATmega128RFA1 microcontroller that can be programmed for all kinds of applications including remote sensor monitoring, or peripheral activation.
Other notable features include:
Very high communication speeds (up to 2Mbps)
Built-in Python interpreter (Who needs a microcontroller?)
Wide low voltage TTL operating range (1.8 - 3.6V)
7 analog-to-digital inputs
6 PWM outputs
9 Interrupt capable pins
Communication options include I2C (TWI) SPI, 2 hardware UARTs
Amazingly low power capabilities (1.6uA sleep current)
F-type antenna etched onto PCB so you don't have to worry about it falling off :)
RF100 footprint & pinout compatible
Embedded ATmega128RFA1 on-board
2 x UART ports for LVTTL serial control or transparent data
Able to be configured to wirelessly program Arduino Uno & Mega 2560
Socket-able (2mm spacing) or solder-able
SNAP, instant-on, self-healing, mesh network operating system
802.15.4 Protocol at 2.4GHz
Maximum range performance: 2.5miles outdoor range (LOS) at 250kbps
24 pins, with 20 general purpose I/O, 7 of which can be 10-bit A/D inputs
This board can do it all - breakout the Synapse RF module pins, give you a USB port/FTDI chip to program, supply it with a regulated 3.3V, integrate a reset switch (for updating & erasing), and also give you mounting options.
Better than XBee at a comparable cost! This module features the powerful ATmega128RFA1, transmitting on 2.4GHz with OTA (Over-The-Air) speeds up to 2Mbps, maximum 4.8km (3 miles) range and an SMA antenna connector for optimum performance.
Ever want to change the species of your RF modules? Now you can evolve your XBees into Synapses! Well that doesn't really make sense but, hey, it doesn't change the fact that you can now do it with this kit!
