Introduction 1.3 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 Miscellaneous • • • • • 1.4 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. 1.5 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. © 2008 Microchip Technology Inc. DS51656B-page 11
