6.1.2 Using PCF2131-ARD with LPCXpresso55S69 development board

Figure 10 shows the required hardware for operation of the PCF2131-ARD and

LPCXpresso55S69 EVK board. This configuration consists of:

• One LPCXpresso55S69 EVK board

• One PCF2131-ARD daughterboard

• One USB-A / USB Micro-B cable

• A PC with Windows 10 operating system

The LPCXpresso55S69 development board is equipped with four USB Micro-B

connectors: P5, P6, P9 and P10. The board can be powered through any USB port.

Using P6 USB connector to connect the board to the PC simplifies the start-up operation

because P6 is designated for debugging and the USB cable thus accomplishes two tasks

at the same time: powering the board, and serving as a data link between the EVK board

and PC. For more details regarding power-up and operation of the LPCXpresso55S69

development board, see the LPCXpresso55S69/LPCXpresso55S28 Development Board
