 Additional features of the board include an 8-pin DIP header labeled IC4 that is mapped for use with a customer supplied Microchip 25LC256 EEPROM. The SPI bus and power signals are mapped to the correct pins so that the user can solder in an 8-pin dip socket or directly solder the IC into the holes. Similarly the IC3 header on the board is mapped for a customer supplied Microchip MCP9701A analog temperature sensor. Additional features of the board include an 8-pin DIP header labeled IC4 that is mapped for use with a customer supplied Microchip 25LC256 EEPROM.

 The prototyping area has 288 through holes, broken into two main sections. One section has 28 3-hole busses. Between the 3-hole busses are two 14-hole busses. There are also a 3V3 bus and GND bus, each with 8 holes. The remaining 160 holes are isolated for mounting whatever will fit using standard solder or wire wrapping methods. The prototyping area has 288 through holes, broken into two main sections.

 Since the board resets between program mode and sketch mode the serial port will disconnect and then reconnect. The MPIDE serial monitor will not work unless there is a delay of at least 5 seconds in the user sketch before it begins to send data to the computer. To ensure the serial monitor is ready it is recommended that users watch the device manager or similar program for your OS after the reset to watch for the reconnection of the serial port before attempting to open the Serial Monitor in MPIDE. The delay is required for proper operation of the serial port so that the board can disconnect and reconnect to the computer before the DP32 begins sending data out while the OS is not listening. This is a byproduct of the embedded USB controller solution on the DP32. Since the board resets between program mode and sketch mode the serial port will disconnect and then reconnect.

 A unique feature of the DP32 from the rest of the Digilent line of chipKIT boards is that the PIC32 microcontroller installed on the board is a removable, 28-pin DIP IC. This allows for lots of flexibility in building embedded projects since you can program the IC with the board, remove it, and then embed it into a stand-alone application without the need to purchase an additional board (additional circuitry is required to embed the IC into stand alone projects). Additional ICs can then be acquired through Microchip directly. Simply go to [[https://www.microchipdirect.com/|www.microchipdirect.com]] and search for "MX250F128B". As of this writing, there are two options for the IC in the DIP footprint, one that comes pre-loaded with the chipKIT boot loader and one that does not. A unique feature of the DP32 from the rest of the Digilent line of chipKIT boards is that the PIC32 microcontroller installed on the board is a removable, 28-pin DIP IC.

 Once you have your new ICs, the original IC can be carefully removed from the socket and the new IC installed on the DP32 board. The new IC can now be programmed with MPLAB tools or MPIDE as described above. If you purchased the IC with the pre-loaded boot loader, you may use either programming environment right away. If you program the IC with MPLAB first, or purchased the IC without the chipKIT boot loader installed, you will need to use MPLAB X to load the boot loader as outlined above if you wish to use MPIDE. Once you have your new ICs, the original IC can be carefully removed from the socket and the new IC installed on the DP32 board.
