Switcheroo Bluetooth Board

Control almost anything with your smartphone! The Switcheroo makes it a snap to upgrade everyday devices for smartphone control.

The Switcheroo can do things like;

  • control toys
  • unlock doors
  • start your car
  • turn on lights
  • open/close your garage door
  • control your heat
  • remote shutter release for cameras
  • upgrade anything with a pushbutton
  • and much more!


Pretty much anything with a button that’s meant to be pushed by a human, and even some stuff that isn’t, can be upgraded with the Switcheroo! they’ve developed a tiny Bluetooth 4.0 Low Energy platform you can use to upgrade existing products to enable direct smartphone control, or use it to develop your own smartphone control projects.

Here is same working examples?

How does it work?

Vehicle keyfobs, toys, garage door openers, TV remotes, and certain home appliances all have push buttons people press to control the device. These buttons typically actuate small internal switches which pass low voltage DC current to a microprocessor when the button is pressed. The Switcheroo can be easily wired into this simple switch circuit to take the place of that switch or act in concert with it, upgrading these devices to allow direct smartphone control. Of course that’s not the only thing Switcheroo can do. It can be used to create custom control solutions for things like access and locking systems, robot and toy control, vehicle ignition systems, etc.

The Switcheroo has 4 opto-isolated outputs that can switch DC voltages from 2 to 24 volts, up to 150mA of current per output. For AC voltages or higher current applications you can connect relays or solid state switching ICs to Switcheroo and do even more!

Switcheroo can operate on a single CR2032 coin cell battery for up to a year (depending on usage), or an optional 3.3v regulator can be soldered in place of the battery clip. With the regulator installed, unregulated DC power between 4v and 20v can be used, which makes upgrading existing devices and products easy – Switcheroo can just sip a tiny bit of power from that device’s existing battery pack or power source.

Security ..

Bluetooth Low Energy itself offers AES-CCM encryption to secure the low energy link between Switcheroo and your smartphone. Switcheroo itself can operate in two distinct security modes: open and secure.In open mode, anyone can connect to the Switcheroo and control any of the outputs. In secure mode, outputs can only be controlled after sending an authorized access code.
