The white stripe is the negative, the longer lead goes to the + side. 1. Introduction This is a carrier PCB with small prototyping area for the Microchip PIC32MX1 IC. It has a 3.3V regulator and so can be used with a 5V supply. 2. Features • • • • • Up to 6V input Prototyping area For use with ByPIC operating system Separate serial socket Size 82 x 25mm Some of the pads are connected to the ground plane and will be more difficult to solder, a larger amount of heat is needed for these pads. 4. Serial Interface The serial connection is designed for a type 3 USB to serial device that simply plugs into the right angled female socket. The pins are correct. The 5V output is used to power the device not the 3v3 output as this PCB has a built in voltage regulator. Any other USB to serial device can of course be used but the pins are likely to be different and so some wiring will be needed. 3. Construction This is a double sided PCB that can be supplied with or without the components. It is a good idea to socket the IC but not absolutely necessary. 3.1.

DTR If using BV_COM2, conveniently the DTR output is connected to the icon with the arrow on it. This will momentarily bring DTR low and makes a very useful reset. To implement this connect the DTR output to pin 8 on J3 (see the circuit diagram) 5. Example Use [see IMPORTANT NOTES: 1. The regulator is MCP type and is not pin compatible with the 78L variety 2. The 6 way connector can be mounted on the underside of the board, this way it will not obscure the text on the top side. 3. The serial connector can fit on the underside of the PCB All of the available pins (except AVSS and AVDD which have their own pins) are brought out to connectors J1, J2 and J3. Pin 1 for each connector has a square pad, with the serial on the left, pin1 will be the top most pin. This means that port RB0 to RB7 will be on connector J1. The PCB is designed to have 4 pin head connectors in rows J1 to J4. DuPont leads can be used to connect to other equipment. As an alternative turned pin sockets can be used, these are ideal for use with telephone wire as a hook up to breadboard. The Pinhead connector is supplied as a 40 way strip, this can be snapped to length and will leave 8 spare. Install the IC socket first followed by the other components. Make sure that you get C3 and ©ByVac Page 3 of 5 ByVac Product Specification BV500 PCB Kit BV500T 5.1. AVSS & AVDD The AVDD and AVSS are permanently connected to 3.3V and ground respectively by a shorting track underneath the jumpers. If a separate analogue supply is required then this track can be broken and the PCB pad used. The short is not shown on the circuit diagram. 5.2. Stand Alone The main reason for supplying a 3.3V regulator is that the board, one programmed can be used as a stand alone device with perhaps a battery power supply. ©ByVac Page 4 of 5 ByVac Product Specification BV500 PCB Kit BV500T 6.
