Here my Linux review of the Odroid N2+.
It has a beastly CPU, but is lacking in I/O.
Here's my video.
 
 
Ubuntu 18.04 - No autofill in terminal. sudo apt install bash-completion Can't change keyboard layout to Belgian 5Ghz wifi adapters not working/No kernel headers to install + Good video playback with Firefox in 1440p res. up to 1440p video. But no VPU acceleration. Light screen tearing. sudo apt update sudo apt upgrade sudo apt autoremove sudo apt install exfat-fuse exfat-utils #for Ubuntu 18.04 sudo apt install bash-completion zram-config geany sudo geany /media/boot/config.ini #set cpu frequency and display resolution XFCE ArchLinux - Display resolution can't be set, not in OS or config.ini No on-board sound. USB audio adapter works Temperatures / Hottest day of the year ------------ Idle OC 43°C Max OC 77°C Heavy throttle at 75°C after 10 minutes from idle Idle default 40°C Max default 73°C Power consumption ----------------- N2 -- - IDLE : ≃ 1.9W (Performance governor) - CPU Stress : ≃ 5.5W - Power-off : ≃ 0.2W N2+ --- - IDLE : ≃ 2.2W (Performance governor) - CPU Stress : ≃ 5.9W (@2016/2208MHz), 6.2W (@2016/2400MHz) - Power-off : ≃ 0.2W SD card reader / sandisk extreme 128GB -------------- 77.8 MB/s read 28.3 MB/s write 0.51 msec access time USB3 with NVMe to USB3 ---------------------- 318.9 MB/s read 215.5 MB/s write The same NVMe on the M4V2 389 MB/s read 392.7 MB/s write eMMC 32GB read 166.1 MB/s - No on-board wifi. Interference with USB3 and 2.4Ghz wifi dongles. Better to use the OTG port for these. Can't change display resolution in OS Throttling at OC clocks + Most powerful ARM CPU in -100$ SBC. Very low consumption.  

Also you need to adjust voltage controller as below. I also attached my dtb file.
Goodluck. If you find something useful please let me know.

After a lot of time around the subject i found that to use GPIO in python3 we need to install the:
 
https://github.com/LeMaker/RPi.GPIO_BP
 
But we need to install it before we try the sinovoip version.
If we install the sinovoip first an after that the lemaker version. It not work.
 
For C, shell and python2 we can use (it works):

tnks for the help
