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.

    FLiP socket. 2) PING))) Distance Sensor Sockets This header accepts the 0.1” pins on the PING))) Ultrasonic Distance Sensor (#28015) and LaserPING 2m Rangefinder (#28041) modules. Copyright © Parallax Inc. SumoBot WX Board (#32132) v1.1 8/17/2020 Page 2 of 9...
  • Page 3: Mounting Holes

    The piezospeaker is connected to P20; drive with frequency-out signals in the 300 to 5000 Hz range. 4) Mounting Holes The four plated mounting holes are positioned to attach the SumoBot WX Board to the robot chassis included in the SumoBot WX Competition Kit. 5) UART Switch The UART slide switch allows the user to change which Propeller I/O pins are connected to the WiFi Module socket's TX/RX serial I/O pins.
  • Page 4 6) ESP2866 WiFi Module DIP Socket A Parallax WX ESP8266 WiFi Module - DIP (#32420D) can be plugged into this socket. This equips the SumoBot WX board to wirelessly program the Propeller on the FLiP module, as well as support other radio applications. When installed, the WiFi module interacts with the ASC LED, D1 &...
  • Page 5 The power switch in position 0 disconnects the input power supply from the entire SumoBot WX board AND holds the Propeller FLiP in reset if it has an external power source connected to its USB port. Position 1 enables everything except power to the servo ports.
  • Page 6 16) QTI Headers The four QTI headers with 0.1” pitch pins are compatible with the Parallax QTI Sensors (#555-27401) that are included in the SumoBot WX Competition kit. Note that the Propeller I/O connection (P12–P15) is the center pin on each of these headers, unlike the SERVO and AUX headers.
  • Page 7: Specifications

    There are four 2-pin Infrared transmitter sockets spaced around the front edges of the SumoBot PCB. Each is a turned-pin style socket with 0.1” pitch, compatible with the Parallax IR Transmitter LEDs (#350-00003) included in the SumoBot WX Competition Kit.
