S32k144EVB Pinout 3.3V not 5V

Hello,

I am using S32k144EVB (evaluation Board).

I cannot finish my project because I see that for pins from headers J1 and J2, for example PTE3, the logical 1, is 3.3 V. I need 5V.

Is there a way to achieve this?

   

Thank you in advance!

Have a good day,

Sorin

Yes you can switch your S32K144EVB to work in 5V mode or 3.3V mode.

If you are powering your board through the microUSB port, then by default it should work in 5V mode.

Solution: (assuming you are powering your board through the microUSB port to a PC)

5V Mode:

   - R63 is NOT populated

   AND

   - R64 is populated with 0 ohm resistor OR solder a male 3-pin header to J10 (by default not present) and plug a jumper between 2-3

Hello Sorin,

If VDD = 5V, log 1 is also 5V at PTE3.

Or do you supply the MCU with 3V3?

Daniel
