P2 WX Adapter Add-on Board (#64007)
This adapter provides a convenient way to add wireless programming and serial communication
capabilities to the Parallax Propeller P2 microcontroller. The adapter connects a Parallax ESP8266 WX
WiFi SIP module to any P2 development board with a standard 2x6 way accessory header.
The WX adapter can be connected to any P2 accessory header for serial-over-WiFi communications. For
wireless programming, look for the P56–P63 header marked with the “RES” logo.
Serial-over-WiFi communications from any accessory header is available with any ESP8266 WiFi SIP
module firmware version. To add the feature for programming the Propeller 2 wirelessly refer to the
instructions for upgrading your ESP8266 WiFi SIP module firmware to the latest version. P2 WiFi firmware
has a drag/drop P2 loader on its self-hosted web page, which will accept a P2 program binary file
compiled in any language.
