: It featured an Intel Quark SE SoC , an x86 host CPU, and a 32-bit ARC architecture core, both clocked at 32 MHz.

: Some modern libraries (e.g., FastLED) were never fully optimized for the Curie, though it remains compatible with the standard Arduino IDE for legacy projects.

: You can occasionally find individual Curie modules or the Arduino 101 (which integrates the Curie chip) on sites like eBay or Tindie.

The Intel Curie was a button-sized "system on a chip" (SoC) specifically designed for wearables and Internet of Things (IoT) devices.
