DEVELOPMENT BOARD FUNCTIONALITY AND FEATURES
The 16-Bit 28-Pin Starter Development Board is an easy-to-use tool that allows you to
start development with dsPIC30F/dsPIC33F and PIC24 devices. Following are the
important features of the 16-Bit 28-Pin Starter Development Board:
• On-board +5V regulator or +3.3V regulator for VDD and AVDD
• USB power source or 9V DC power source input jack
• Power-on indicator LED
MPLAB ICD 2 Connections
• MPLAB ICD 2 programming connector
UART Communication Channel
• Single UART communication channel via USB bridge
Device Clocking
• 7.37 MHz crystal

Reset push button for resetting the device
Four LEDs for status indicators
Push button switch (SW1)
Potentiometer (RP1) for use with ADC
All device I/O pins are brought out to a header for test point and prototyping
access
DEMONSTRATION PROGRAM
The 16-Bit 28-Pin Starter Development Board is supplied with a preloaded device that
demonstrates the following board functionality:
• Interrupt handling using Timer1 to toggle the LEDs
• UART functionality using the on-board USB to echo characters sent from a PC
terminal programmed with a 9600 baud rate
Refer to Chapter 3. “Demonstration Program” for additional information.

POWER SELECTION
The 16-Bit 28-Pin Starter Development Board has the option of being powered by a 9V
DC power supply or by the USB bus. The position of jumper JP1 determines which
power source is used. Connect jumper pins 1 and 2 for the 9V power supply or jumper
pins 2 and 3 for the USB.
In addition, jumper JP2 selects either +5V or +3.3V power source for the targeted
device. For dsPIC30F devices, connect jumper pins 1 and 2 for the +5V operation. For
dsPIC33F and PIC24 devices, connect jumper pins 2 and 3 for the +3.3V operation.
