Data Sheet

The Parallax Wi-Fi module is designed to support over the air (OTA) firmware upgrades. So

let’s say you purchased the Wi-Fi module, and some time later, the firmware gets upgraded by

Parallax or its community to support more cool applications. If you want your Wi-Fi module to

support those applications too, all you have to do is download the firmware from the Parallax

web site, unzip it, and then use this page to choose the file (with a .ota extension) and load it

into the Wi-Fi module.
