PICBrain11 Module (Revision B)

Table of Contents

This document is also available as a PDF document.

1. Introduction

The PICBrain11 module can control up to 11 sensor and actuator modules. It uses a PIC16F876 microcontroller from MicroChip®. There is on board RS-232 level conversion circuitry so that the PICBrain11 can be directly connected to a PC serial port. There is an on-board 5 volt regulator for supplying regulated voltage to other sensor and actuator modules.

2. Programming

There is no programming specification for the PICBrain11 yet.

3. Hardware
