Microduino-smartRF

Microduino smartRF uses the latest high-performance CC1101 wireless communication chip, which can be widely applied to various short distance wireless communication field

Features

  • Highest working rate at 500KBPS, supports 2-FSK, GFSK and MSK modulation;
  • Modify baud rate, power, frequency and other related parameters by software;
  • High sensitivity (Under 1.2KBPS - 110dDm, 0.1% packet error rate);
  • Low power consumption (1.2 KBaud,433 MHZ RX is 15 ma);
  • Built-in hardware CRC error detection and control point to multipoint communication address;
  • Programmable control output power, the maximum output power is +10dBM;
  • Wireless wake up function, support low power electromagnetic wave activation function;

Specification

  • Low working voltage: 1.9 ~ 3.6V;
  • Support 315/433/868/915MHZ ISM frequency band;
  • Support 2-FSK、GFSK and MSK modulation;
  • Lowest working rate is 1.2 KBPS, up to 500 KBPS;
  • Separate 64 byte RX and TX FIFO buffer;
  • 125 optional channel work, meet the requirements of multipoint communication and frequency hopping communication;
  • Support RSSI strong and weak signal detection and carrier listening function;

Document

Eagle PCB download: Main chips

Development

Application library downlaod: http://code.google.com/p/panstamp/downloads/list

Test program download: https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Texting/Microduino_SMARTRF

Application

You can download the test program that Microduino supplied, and use the Microduino-OLED module to test Microduino-smartRF.

  • Prepared Hardware:Microduino FT232R, Microduino Core and Microduino-smartRF;
  • Prepared Software:Microduino's test program (Arduino), Arduino IDE (upper to 1.0 release);
  • Two Microduino cores use the Microduino-smartRF to communicate, master machine sends the running time to slave machine and use the OLED to display;
    • ceshi_SMARTRF_T is the master machine send program, ceshi_SMARTRF_R is the slave machine receive program.
    • Master machine needs Microduino Core and Microduino-smartRF module; Slave machine needs Microduino Core, Microduino-smartRF and MIcroduino-OLED. Microduino FT232R use to download program.
    • Use the IDE to open the test program and download to master and slave machine respectively.
    • After download, OLED will display "Rec. pack #xx", ”xx” is the time that receives from master machine;
    • Restart master machine, timing starts from zero, slave machine's data also updates at the same time.
