Thanks for photo! Mine is missing too.... I do not understand this Xunlong decission...

Please... Could someone to take a photo of BSN20 MOSFET in te PCB? I would like to check my Orange Pi Zero Plus 2. Thanks in advance

At last the guilty was not my weak charger/psu, the issue was at client side. My PC, my samba client, connects to 2.4Ghz wifi sometimes and connects to 5Ghz wifi anothertimes. 2.4Ghz -> poor network throughput, 5Ghz -> good network throughput. It was not a kernel problem, nor power/hardware issue. It is my fault, sorry for confusion.

It is probabily for my weak charger/psu. I only need 0.5a but my weak charger/psu only get 4.88v at 0.45a. With an estimated vdroop of 0.2-0.3 with my usb cable ( 1 meter, not AWG20... ) my orange pi probabily get 4.6v. I am not very sure, I am going testing that some days.

Another time poor network throughput with last kernel ( 5.37.180117 - 4.14.18-sunxi64 ). Is it possible to select another kernel ? At last It was an issue in my PC, at samba client side. My PC connects to 2.4Ghz instead of 5Ghz one Thanks in advance

uooohhhh!!!!! What a tiny "big" CPD!!!!! ;-) Thank you very much, guidol. It is a very good reference for me. Now, I have moved my orange pi zero plus H5 to a very open-space ( it was inside a very closed furniture before.... ). I have moved it behind my plasma TV ;-). And now, almost idle, temperature is in normal values ( with 21C room temperature ): root@zeus:~# armbianmonitor -m Stop monitoring using [ctrl]-[c] Time CPU load %cpu %sys %usr %nice %io %irq CPU C.St. 22:02:28: 816MHz 0.36 10% 1% 1% 3% 3% 0% 47.2°C 0/2 22:02:33: 816MHz 0.33 4% 1% 2% 0% 0% 0% 44.4°C 0/2 22:02:38: 816MHz 0.31 2% 1% 1% 0% 0% 0% 45.0°C 0/2 22:02:43: 816MHz 0.28 2% 1% 1% 0% 0% 0% 42.2°C 0/2 22:02:49: 816MHz 0.34 2% 0% 1% 0% 0% 0% 44.3°C 0/2 22:02:54: 816MHz 0.31 3% 1% 2% 0% 0% 0% 45.3°C 0/2 22:02:59: 816MHz 0.29 2% 1% 1% 0% 0% 0% 46.2°C 0/2 22:03:04: 816MHz 0.34 2% 0% 1% 0% 0% 0% 43.0°C 0/2 22:03:09: 816MHz 0.32 6% 1% 5% 0% 0% 0% 47.2°C 0/2 22:03:14: 816MHz 0.29 2% 1% 1% 0% 0% 0% 44.5°C 0/2 22:03:19: 816MHz 0.27 3% 1% 1% 0% 0% 0% 43.9°C 0/2 22:03:24: 816MHz 0.25 3% 1% 1% 0% 0% 0% 45.4°C 0/2 22:03:29: 816MHz 0.23 2% 1% 1% 0% 0% 0% 44.9°C 0/2 22:03:34: 816MHz 0.21 5% 1% 3% 0% 0% 0% 45.4°C 0/2 Time CPU load %cpu %sys %usr %nice %io %irq CPU C.St. 22:03:39: 816MHz 0.19 2% 1% 1% 0% 0% 0% 44.2°C 0/2 22:03:44: 816MHz 0.17 2% 1% 1% 0% 0% 0% 44.6°C 0/2 22:03:50: 816MHz 0.16 3% 1% 1% 0% 0% 0% 44.3°C 0/2 I use my OP Zero for NAS Server ( samba/nfs ) and for p2p downloads with mldonkey. You can see my brico-project with an old celeron heatsink ( I am very worried with temperatures, perhaps I am a little friki... ):

Guidol... Do you have any active cooling? Your temperatures are very low...

It is very strange.....

Showing Temperature is missing in last two kernels: root@zeus:/sys/class/thermal/thermal_zone0# uname -a Linux zeus 4.14.13-sunxi64 #35 SMP Tue Jan 16 17:51:14 CET 2018 aarch64 GNU/Linux root@zeus:/sys/class/thermal/thermal_zone0# armbianmonitor -m Stop monitoring using [ctrl]-[c] Time CPU load %cpu %sys %usr %nice %io %irq C.St. 20:50:25: 816MHz 1.82 22% 3% 3% 4% 10% 0% 0/2 20:50:30: 816MHz 1.83 16% 3% 1% 6% 5% 0% 0/2 Although, you can see it manually: root@zeus:~# cat /sys/class/thermal/thermal_zone0/temp 59169 root@zeus:~# cat /sys/class/thermal/thermal_zone0/temp 62678

Hello again, New kernel, new news. I am getting very good network throughput again with last kernel 4.14.10-sunxi64. I am getting 30MB/s transfer speed with my config, via samba with an USB 2.0 HDDD as bottleneck. Great!!

hello, Trying last kernel, 4.14.8-sunxi64, I am getting a very poor network throughput, only 3.98MB/s via samba.... Before that, I got 30MB/s ( via samba with my USB 2.0 HDD as bottleneck ). Furtheremore, I see a max CPU Freq at 812Mhz ( before 1Ghz ) and very high temperatures at idle... Perhaps CPU Freq Scaling is not fully implemented. I am very excited with this little board and I am sure I am going to see some improvements soon. I had been using an Orange pi One with armbian for one year very happy. This board, Orange Pi Zero Plus, is my gigabit upgrade as NAS. Great distro armbian!! Thank you armbain-team! Best Regards
