SumoBot WX Board (#32132)

The SumoBot WX board sports a socket for the Propeller FLiP Multicore Microcontroller

Module (#32123), providing power and I/O and connections to the wide array of

on-board peripheral sockets and headers. Clear labelling, status indicator LEDs, and

on-board piezospeaker support successful project building and operation.

Designed specifically for the SumoBot WX Robot Competition Kit (#32134), the board's

corner mounting holes align with the SumoBot chassis. 3-pin servo ports and an

onboard boost regulator support robot locomotion. Additional headers and sockets

accommodate sensors included in the Competition Kit, as well as optional accessories.

The WX socket accepts a Parallax WX ESP8266 WiFi - DIP module (#32420D) for

optional wireless programming and communication.
