2.3.1
MCP2210 Breakout Board Operation
The MCP2210 Breakout Board can be used with either the provided motherboard, or
as a stand-alone USB-to-SPI (Master) bridge module. The breakout board provides all
the required signals in order to assist the user in building customized boards using the
MCP2210.
as a stand-alone USB-to-SPI (Master) bridge module. The breakout board provides all
the required signals in order to assist the user in building customized boards using the
MCP2210.
The breakout board has the following features:
• SPI bus signals (MOSI, MISO, SCK)
• 9 GP signals configurable for:
- GPIO functionality (digital input or output pins)
- Chip Select functionality (working with the SPI bus signals)
- Dedicated function pins
• Jumper selectable power supply: 3.3 or 5V (up to 500 mA). The board has a
default connection trace between V
DD
and 3.3V rail, making the voltage header
mounting unnecessary when powering the board with 3.3V. For 5V operation, a
3-pin header must be mounted on the board.
3-pin header must be mounted on the board.
• PICkit™ Serial Analyzer header using GP4 as the Chip Select signal
• Dip form-factor (0.6 inches overall row spacing between pins)
By using the provided software and libraries, the user can create personalized PC
applications using the breakout board as a USB-to-SPI (Master) bridge adapter.

MCP2210 Breakout Board Operation
The MCP2210 Utility software was created for custom device setting requirements. A
few of the settings that this utility can alter include VID, PID, power requirements, and
string descriptors. A download link for this software can be found on the board web
page. For instructions on the use of this software, refer to the software’s supporting
documentation included within the application install package.
