ProtoBoard Expansion

Microchip PIC 16XXX Family Prototype System

For small micro controller applications based on 18 pin PIC16XXX devices, ProtoPOD has all the core support circuits you need for a stand-alone prototyping system.

The regulated +5 volt supply and clock circuit means you don't need to worry about building stock circuitry before diving into your own design.

Of course, the prototype array is where you build your circuits but if there's not enough room there, the header on the edge of the card provides expansion.

ProtoBoard/ProtoPOD

BitScope ProtoPOD

Our ProtoBoard Kit is supplied with a cable for use with BitScope. The header strip at the left of the card is configured with a 26-way header for direct connection to BitScope.

BitScope supplies V+, V- and +5 volts so ProtoBoard does not need an external supply when used this way. BitScope's 8 digital and 2 analog inputs may be wired into your prototype circuit as needed.

This makes for a self contained prototype system that you just plug into BitScope to activate.

PIC ICE Probe

PIC ICE Probe

When you need to analyse an existing circuit that has a PIC in it you may wish to observe signals at the PIC pins to diagnose a fault.

ProtoBoard can be configured to do this non-invasively.

You insert the target PIC in socket U1 on ProtoBoard and insert an 18 pin DIP plug to the header pins adjacent to U1 to connect the cable to be inserted into the target circuit or PCB.

Connect ProtoBoard to BitScope and you have a fully functional ICE probe for debugging your existing PIC designs. The prototype area even allows you to add signal generation or test circuitry if required.

Data Logging

ProtoBoard includes a serial interface which can be used as the basis for any number of data logging projects. The PIC may be programmed to monitor some external variables and then transmit the data to a remote PC as required.

The prototype area can easily support enough analog circuits to implement simple monitoring circuits. If a more robust serial connection is required, 2 RS485 drivers (like 75176) could be wired into the 20 pin socket above the PIC. RS485 can operate over distances up to 1Km at low serial rates and is well suited to telemetric logging applications.
