This easy-to-use module is capable of sending and receiving serial data wirelessly between microcontrollers or to a PC. Low power consumption makes it ideal for use in battery-powered applications. Data is sent and received by AM or CPCA modulation, thus offering a higher average output power which extends the range. This module is equipped with an RSSI feature that can be utilized to improve power efficiency by waking up circuitry only when an external signal is detected.

Key Features:

  • High speed data transfer rates: 1200-9600 bps.
  • Compatible with most microcontrollers including the Propeller chip and all BASIC Stamp models.  
  • SIP header allows for ease of use with breadboards.  
  • Power-down mode for conservative energy usage (longer battery life).  
  • Line of sight range up to 250 feet (depending on operating conditions).


  • Voltage requirements: 3.3 - 5 VDC.
  • Current requirements: Transmit: 12 mA, Receive: 6.1 mA, Power Down: 11.5 uA.
  • Communication: Asynchronous serial data @ 1200-9600 bps (TTL/CMOS compatible).
  • Dimensions: 3.82 x 0.94 x 0.41 in (97 x 24 x 10.5 mm) *includes antenna.
  • Operating temp range: +32 °F to +158 °F (0 °C to +70 °C).
