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 switchable internal /external antenna.

Description [Hide]

XBee is good; Synapse is just better. More I/O, embedded Python, and generally better range at comparable cost! Synapse Wireless provides reliable RF Engines®that support a range of frequencies and bandwidths. These small, low-power, transceiver modules, commonly run in the 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, mesh networking, and/or peripheral activation.  Other notable features include: very high communication speeds (up to 2Mbps), large transmission range (up to 3 miles LOS at 250Kps with U.FL  antenna), wide Low voltage TTL operating range (1.8 - 3.6V), 7 Analog-to-Digital Inputs, 6 PWM Outputs, 9 Interrupt capable pins, I2C (TWI), SPI, 2 x UARTs, & amazingly low power capabilities (1.6uA sleep current).

These new RF220UF1 modules also include both a Power Amplifier (transmit) and a Low Noise Amplifier (receive).  Transmit power has been increased to a whopping +20dBm!

This unit comes with both a U.FL connector and an internal F Antenna.  You can select your antenna choice in software!
