Particle
Welcome to the Particle community! to share projects and receive help.

The Spark Core is a tiny Wi-Fi development kit based on Texas Instrument's CC3000. We launched it on Kickstarter in 2013, and we've shipped tens of thousands of them. You can either buy with chip antenna or u.FL connector if you would like the option to boost signal strength.  The Core with uFL connector requires a separate flex or duck antenna. 

Specs:

  • Texas Instruments CC3000 Wi-Fi module
  • STM32F103 72Mhz ARM Cortex M3
  • 128KB flash, 20KB RAM, 2MB external flash
  • 802.11b/g
