1. Introduction

The ProtoPIC RoboBrick is a RoboBrick with a socket for either an 8-pin PIC (e.g. PIC12C509, PIC12C672, etc) or a 14-pin PIC16C505. The rest of the board has plated through holes on a .1 inch grid for attachining other components.

For the 8-pin PIC's, a jumper selects whether the SIN pin (N1) is connected to GP3 or GP4. GP5 is connected to SOUT (N1).

2. Hardware

The hardware consists of a circuit schematic and a printed circuit board.

2.1 Circuit Schematic

The schematic for the Protopic RoboBrick is shown below:

3. Issues

The following fabrication issues came up:

• The holes on N1 are too large (size 3) and need to be made smaller (size 2).
