1. Out of the Box

The NXP EasyEVSE EV Charging Signal Board is an add-on board for several EV charging development platforms. This get started helps you to get the board up and running which integrates with an NXP host platform evaluation board. The main host of the system is on a separate processor development board. For EVSE simulation, the host platform board can be a i.MX 8 or 9 applications processor boards (MIMX93-EVK) or a i.MX RT crossover MCU board (MIMXRT1060/1064-EVK).

For EV simulation the host platform can be a i.MX 8 or 9 applications processor boards (MIMX93-EVK), a i.MX RT crossover MCU board (MIMXRT1060/1064-EVK), a S32G automotive processor board (S32G-VNP-RDB3) or a S32K3 MCU board (S32K3X4EVB-T172).

2.1 Get Familiar with the Board

The NXP EasyEVSE EV Charging Signal Board takes the power from the host EVK connectors, for example, Arduino, EXP-CN, or MFP connector. To drive external relays (140 mA or above generated at 12 V), the board has a DC power jack for supplying 5 V external power. The kit comes with an 5V DC power supply. For using additional power supplies, please refer to the User Guide.
