This adapter was designed to connect the Onion Omega WiFi module to any of our Particle Electron IoT devices.
This adapter includes a Level-Shifted I²C Communication Bus and a USB interface for programming the Onion Omega. This adapter is compatible with the OOKF Key Fob Receiver Shield for Onion Omega.
This adapter maps the I²C and Power connections only.
We have designed 3 types of adapters for Onion Omega to better suit the subtle size differences between controllers.* The vast majority of devices are compatible with the Type A adapter. Type B and C are for special-use cases. While Type C is also compatible with most devices, Type B will have fitment issues with many controllers, though it may be useful in certain circumstances.
Type A: Brings the Onion Omega to the front of the PCB with a bias to the right side, allowing taller components to peacefully coexist on the left side of the adapter.
Type B: Brings the Onion Omega to the front of the PCB with a bias to the center and slightly to the right, allowing taller components to peacefully coexist on each side of the adapter.
Type C: Keeps the Onion Omega 0.200″ from the front of the adapter, and is horizontally near center with a slight bias to the right.
*Please contact us if you are unsure of the adapter to use for a particular device. WE WILL CONTACT YOU IF YOU HAVE CHOSEN AN ADAPTER THAT DOES NOT FIT A CONTROLLER ON THE SAME ORDER.
