KC868-A16v3 integration with 5V sensors and loads ?

[Alx]

Hello,

I am planning a project based on the KC868-A16 v3.1 (REV:1.6) board. My peripheral types include 5V digital sensors (TTL/CMOS) and low-power 5V loads.

Could you please help me with the following technical questions:

1. LO0 and LO1 with 5V: The official documentation specifies 12V/24V for the LO0 and LO1 power supply. Is it safe and functionally possible to apply a 5V external voltage to these specific channels instead?
   
2. Onboard 5V VCC Usage for LO0 and LO1: Can I use the internal 5V VCC rail from the board to power the LO0 and LO1 loads? The total load current will be under 1A, which is within the XL1509-5 regulator capacity. Are there any internal limitations preventing this?
   
3. 16 Digital Inputs with 5V logic: How can I modify all 16 Digital Inputs (INPUT1 and INPUT2) to safely and accurately read active 5V digital signals (TTL/CMOS)? What is the exact hardware modification procedure for the PCB?
   

Thank you.

1: A16v3 mosfet output at least >9V DC.
2: can't use by 5v DC output.
3: you can try whether can detect by 5V. because >5v is logical FALSE.
