How can you add cloud connectivity to low cost-embedded systems without adding a ton of custom firmware to your target system? Introducing the Wisplet, connecting both non-smart or newly-developed intelligent devices to the Internet of Things.

with no coding necessary, the wisplet is simply the easiest way to safely connect your devices to the Internet of Things


Versatile and cost-effective,the Wisplet module:

  • Helps engineers and developers connect any product to the IoT – both existing or new products
  • Reduces barrier to installation by integrating with your existing infrastructure
  • Handles over 90% of the connectivity process
  • Compatible with low-cost, 8-bit, 16-bit and 32-bit systems
  • Wisplet S2W features a simple serial interface to the product hardware. Or Contact Us to learn about our other Wisplet modules, including Bluetooth (BTW)

Cutting-edge cloud connectivity

The OLD way

  • Requires an expensive, powerful host computer for most of its software
  • Software is an add-on and an additional expense
  • It's difficult to update
  • IT needs to be involved

The new way

  • Needs no host computer
  • Handles over 90% of the connectivity process
  • Wisplet IoT Architect™ Tool reporting rules software is included
  • Firmware is preloaded and updates are automated

New or Retrofit. Let's get connected.

How simple is it to get your get your products talking to each other and connected to the Internet of Things? It's as a easy as 1, 2, 3!

Step 1. Purchase Wisplet development kits

Step 2. Program the included Wisplet IoT Architect ™ Tool software- no coding skills required

Connect module to sensors -- whether new or retrofit -- and the cloud

Build the alert handling rules to push to the Wisplet module

Develop security policies and beta test

Step 3. Deploy

Manufacture product device hardware with integrated Wisplet
