The Firefly is a breakout board designed to inspire, build and develop from scratch any Internet of Things application.

To work out of the box, the firefly includes a PCB antenna for the Sub-1GHz interface, ceramic antenna for 2.4Ghz and 1 x u.Fl connector for sub-1GHz external antenna.

The firefly can be programmed and debugged over JTAG and USB. The board has a CP2104 USB to serial converter with a PIC, it allows to program the CC2538 without having to manually to put the device in bootloader mode.

The Firefly platform has been widely used to test and develop with OpenThread

  • ISM 2.4-GHz IEEE 802.15.4 & Zigbee compliant.
  • ISM 868-, 915-, 920-, 950-MHz ISM/SRD Band.
  • On-board printed PCB sub-1GHz antenna, alternatively u.FL for sub-1GHz/2.4GHz external antennas.
  • AES-128/256, SHA2 Hardware Encryption Engine.
  • ECC-128/256, RSA Hardware Acceleration Engine for Secure Key Exchange.
  • Compatible with breadboards and protoboards.
  • On-board CP2104/PIC to flash over USB.
  • User and reset buttons.
  • RGB LED to allow more than 7 colour combinations.
  • Small form factor (53x25mm).
  • The Firefly can be seen as the "small brother" of the RE-Mote, with a slick design and a lower cost.
