CF3 Common Flexible Form Factor

Enables flexibility to migrate between technologies and future-proof product designs

CF3 Graphic

Common across product generations
Flexible to support any wireless technology
Form that scales between module families
Factor with defined footprints and pin-outs

Since launching the first cellular embedded module in 1997, we've learned the three things that matter most to our customers:

  1. Compact size is required for many new IoT applications
  2. Common footprints and consistent software interfaces simplify migration between technologies

No matter what wireless technology you start with, your CF3® investment is protected, lowering your total cost of ownership and giving you more possibilities in future product designs.

Why CF3®?

Easy to Start

Faster design-in, with dedicated pins for expansion and customization.

Easy to Design

Less design complexity, with scalable performance in the same footprint.

Easy to Deploy

Simpler manufacturing, with fewer device variations to stock and more flexible assembly.
