S32K144 SmartWheels Micro EV3 with OLED Display + SmartWheels IO Shield

The SmartWheels EV3 is a low cost development board based on the NXP S32K144UAT0VLLT microcontroller. The S32K144 offers functional safety compliance with ISO26262 ASIL Class B. The SmartWheels EV3 is equipped with onboard Segger J-Link Debugger along with CAN2.0B transceiver, 1.3” OLED Display and TDK ICM-42670-P 6 Axis IMU sensor. This makes the SmartWheels EV3 a complete development package in itself. The SmartWheels EV3 also allows the user to switch between 3.3V and 5V logic along with the ability to change the ADC Reference voltage between 3.3V and 5V. It makes the SmartWheels EV3 extremely flexible for prototyping. The SmartWheels EV3 is made in a breadboard Compatible form factor offering 74 GPIOs for utilizing various peripherals of the S32K144 microcontroller. The board also integrated a RGB LED along with 2 push buttons.

  Powering the SmartWheels EV3

The SmartWheels EV3 can be powered by 4 different methods. It is highly recommended that the user supplies a voltage of 5V to the SmartWheels EV3 in order to use all sensors and peripherals on the SmartWheels EV3. The onboard Voltage Reference and the CAN transceiver require 5V to stay operational. Please note that powering the SmartWheels EV3 with 5V is not the same as selecting 5V on “VMCU SELECT'' Jumper. It means that the SmartWheels EV3 board must be supplied with 5V. The user has full control of choosing appropriate MCU voltage without affecting the operation of any onboard peripheral or sensor.. However They are listed below:

1. J-Link (USB Type-C)

2. 5V Power Pin

3. 3V3 Power Pin

4. JTAG Connector
