There is no problem other than potential users confusing A (amperage) with V (voltage). Once you are aware of the problem and act on accordingly there is no problem any more. You just need a SHORT cable with thick power wires between PSU and board. But M4 users buy a thick PSU with insanely high amperage ratings and use long and rather thin cables. It's not 'not enough amperage' but almost always 'crappy power cables'. Once you understand this you're done.

If you order this cable https://www.friendlyarm.com/in…ct/product&product_id=231 and combine it with a 2A/5.1V PSU you're already done (I did all my M4 NAS testing with exactly this setup). But users choose an expensive PSU with high amperage ratings and combine it with a long and crappy cable and the problems start.

The M4 in my opinion is still the best NAS SBC thingy if you've already 3 or 4 USB3 disks around. If it's just two a few other RK3399 boards become also attractive, especially RockPi 4 and RockPro64.

Wrt ODROID-H2 IMO the only interesting thing with this 'board' is the low idle consumption. Unfortunately Hardkernel is not able to provide definitive idle numbers (the 4W they claim are worthless unless they comment on whether they had no, one or even two displays connected). But right now Hardkernel's x86 knowledge/support is still in it's infancy so I would better study some threads/problems in their forum first prior to any buying decision.

Are you sure 2A/5.1V PSU is enough because friendlyarm on the wiki mentions "Power Input : 5V/3A" and sells a 5V/4A for the M4 on their website. And I'm planning using all four usb ports and hostapd ...

Sure, there's just one problem (or two) with this board: Prone to undervoltage and users not able to understand the difference between voltage drop and 'not enough current'. NanoPi M4 does not support USB PD (power delivery specs) and powering with 'dumb' 5V PSUs and the 'usual' (AKA insufficient) cabling between PSU and board results in malfunction in a lot of installations.

Disclaimer: While I have 2 M4 I never tested wireless and especially not AP mode so no idea whether this works out of the box or with more than 2-3 clients.

The rather expensive Gemini Lake thingy from Hardkernel? Or HC2?

Thanks for your advices, I think I'm gonna give up on the M4, what about MiniPC T4, it has a different PSU, does it suffer from the same problems?
Hardkernel products seem to have good feedback from users, however HC2 has only one sata port and one usb2 port. Even if i connect the first HDD directly to the SATA port I would have to connect the second (usb3) HDD to the usb2 right?
Regarding the H2 it is much more expensive and more power consuming since is not an arm board. If I was to go for a x86 I think I would reuse an old AMD E-350 mini PC which I don't use anymore (but I want to reduce power consumption to a minimum since it would be on for 24/7).

Hi,

I'm planning buying an Nanopi M4 4Gb for OMV. I plan using OMV for smb sharing (I have 2 usb3 hdd), download manager and backup (Urbackup or Duplicati). Additionally I also plan to use the SBC for hostapd, tvheadend and home assistant. Is Nanopi M4 ok for this? does anyone recommend another SBC over Nanopi in the same price/energy consumption range?

Regards,
