The DM300027 is a low-cost, 16-bit, 28-pin Starter Development Board that supports 28-pin PIC24 microcontrollers or dsPIC Digital Signal Controller (DSC) devices. This board is an ideal prototyping tool to help validate key design requirements using these microcontrollers and DSCs.
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.
The dsPIC30F/dsPIC33F and PIC24 devices use an on-board PIC18 and USB interface for UART communications. With switch SW2 in the USB position, the PIC18 device communicates with the target device through the UART module. The PIC18 will then complete the UART-to-USB bridge. The appropriate USB device driver must be installed prior to UART-to-USB communication.
