Eddie Control Board with Power Connector (#28993)
Eddie Control Board PCB (#550-28990)
The Eddie Control Board provides a complete single-board solution to control the Eddie Robot Platform
(28992). Designed to be flexible and expandable, the Eddie Control Board is also well suited for other
mobile robot platforms. While the board has a wide input voltage range, it is primarily targeted to
12 VDC battery-powered applications.
The heart of the Eddie Control Board is the Propeller P8X32A microcontroller. The Propeller chip’s eight
32-bit cores provide incredible power and flexibility. The board includes high-current motor drivers, an
eight-channel 10-bit ADC, and access to lots of digital I/O. Multiple regulated power supplies (12 V, 5 V,
and 3.3 V) and three switchable auxiliary power ports support optional accessories for your robot.
This document provides details and specifications about the Eddie Control Board hardware only. For
additional information and for details about the latest firmware, go to www.parallax.com/eddie.
