synapse

Well, I can’t believe I have not seen this module before. I may have but discounted it because it is about $11 more than an Xbee Series 1. However, the features in this module are very compelling, you really get a LOT of extra power and features for that $11.

This Synapse RF module-in-an-XBee-Pro-form-factor features OTA (Over-The-Air) speeds up to 2Mbps, maximum 1.2km (4000) range and a chip antenna for compact installation.

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, remote control, or peripheral activation.

Features:

  • XBee Pro pin and footprint compatibility
  • Very high communication speeds (250kbps to 2Mbps)
  • Up to 1.2km (4000′) foot range (line-of-sight)
  • Built-in Python interpreter (Who needs additional microcontroller? This one has one built-in!)
  • Wide low voltage TTL operating range (2.7 – 3.6V)
  • Ultra low power consumption mode (1.18µA. Not mA, but µA!)
  • 15 GPIO, featuring
    • 4 10-bit A/D inputs
    • 4 PWM Outputs
    • 7 Interrupt capable pins
  • 128k flash, with 58k free for over-the-air loaded user programs
  • Communication options include I2C (TWI) master mode, SPI (3 & 4 wire, master mode), 1 UART
  • Low power capabilities (2.3uA sleep current)

More:

  • Embedded ATmega128RFA1 on-board
  • 1 UART port (pin 2, 3) for LVTTL (3.3V) 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
  • I2C communication (Pins 9, 13)
  • SPI communication (Pins 18, 19, 20)
  • 128k flash memory (56k available for user applications)
  • Can be used stand-alone (no additional microcontroller required)
  • Low power mode of 2.3uA with internal timer running
  • Supply voltage: 2.7V~3.6V
  • Transmit current: 130mA (Typ)
  • Receive current: 25mA
  • Sleep current: 2.3uA
  • Operating temperature:-40°C ~ 85°C
  • Power output: 20dBm for best-in-class range
  • FCC certified on all 16 channels (2.4GHz)
  • Spread spectrum (DSSS) technology resists noisy environments
