OOPicHub15 Robobrick (Revision A)

Table of Contents

This document is also available as a PDF document.

1. Introduction

The OOPicHub15 RoboBrick is a master RoboBrick that can control up to 15 slave RoboBricks. It uses a OOPic (or OOPic II) microcontroller from Savage Innovations. It contains a battery connection, power switch, and a 5 volt linear voltage regulator with fuse.

2. Programming

There is no programming specification for the OOPICHub15 RoboBrick yet. However, the table below allows you to figure out which pins on the OOPIC II go to the connectors on the OOPICHub15.
