Functional Description
The DKSB1001B is a break out board for Microchip’s dsPIC33 in a 100 pin TQFP. This board offers developers access to a high pin count, small package part, while maintaining maximum flexibility. Each microcontroller pin has its own external output pin on the board. Every I/O is accessible via the unpopulated 0.1” headers.
Power
The 5V regulator has large input range of 5-15VDC. It can supply a maximum of 1.0A.
LEDs
The board has two LEDs. D1 is a power indicator. D2 is a general purpose LED available to the developer. Removing JP1 disconnects D2 from the microcontroller’s I/O pin.
Reset
The on-board master reset S1 allows for easy restart of applications. A reset pin is also available on header J2.
Oscillator
Since it has an internal oscillator, the microcontroller can operate without an external oscillator. However, an external half-size DIP oscillator socket is provided for applications that require precision clocking. Oscillator frequencies up to 50 MHz are available from Digi-Key.
Programming and Debugging
The board employs an RJ-11 socket for programming and debugging with Microchip’s standard development tools.
