So is this 100% interchangable with the Arduino Leonardo ETH model as it also now has w5500 built in. And is compatible with Cheyene IOT system?

Hi, the voltage regulation at 5V has a ripple, enough to not be able to use touch sensors, what do you recommend? add a filter? what kind of filter?
JaneYu Hello, i obtained one of the v1 boards and heard there are some issues with PoE, can you tell me exactly what these issues are and when they show up?
I'm also planning to drive a 28byj-48 stepper motor with this board, is there Information available how much current i can draw from the 5v pin when powering the board over PoE? And if there is any possibility to get a higher voltage than 5 volts anywhere on the board?
Thank you,
Jan
JaneYu Hello, From the POE power input the internally generated voltage is directly 5v? Is there an internediate lower volatage, like 12v available internally somewhere in the board (at the Vin pin, for example) that could then be used to power a PIR module, for example?
JaneYu I have order 50 of these arduino for POE capabilities.
First batch of 10 is ok but all other have potential issue with SI3402 POE Chip. after 4 weeks of countinuous power, the arduino power down and no 5v at all.
I Think is a defective batch of SI3402 chip....
Can you help me on this case ?
Thanks a lot

JaneYu If you think this batch is defective, you'd better contact [email protected] for after-sale servive
I had the same problem, but DF Robot support department was very helpful and sent me the replacement ASAP. A new version came out recently, they say it may solve the problem, I haven't try it yet. Apart from that it works great.
My leonardo hasn't lost the bootloader.
Have you read the post i am linking in the first comment i made ?
Here is the link again : https://www.dfrobot.com/for...
Read it first then you'll understand what i need ;-).
Thank you.

JaneYu why do you want to use an external ISP programmer to upload the code, since the main controller is Leonardo, you can use it just like a normal Arduino board
JaneYu Hi,
I want to reclaim the 4k of memory used by the bootloader for my program space. I am out of programming space for my current application using this board. If I could free up the memory used by the bootloader i would be ok. The way to do so i by using an external ISP Programmer to upload my code but it does not work. Is there a special way to program using the ISCP header ?
Yes, tested with org IDE ethernet 2 library. works well. And it also support POE function.
