any problem?

Yes, what are the Linux GPIO numbers for pins 2-6?

No voltage step-down included in the battery box I pointed to, inserting 8 fresh AA batteries resulted in 13.39V and not 5V :-(

I was able to use $2.20 ENC28J60 ethermet module bought for Arduino with Raspberry Pi Zero, should work with Nanopi Neo Air as well: https://www.raspberrypi.org/forums/viewtopic.php?f=44&t=152965&p=1015300&hilit=ENC28J60#p1015300 Hermann. https://stamm-wilbrandt.de/en/forum/IMG_20160726_...

As posted previously I did order the FriendlyArm 3.99$ Ipex wireless antenna. I found many cheaper antennas on aliexpress as well, and did order 5 different (free shipping) as well. Today the 1st of the 6 antennas arrived (China - Germany in 14 days): https://www.aliexpress.com/item/2-4G-Soft-Antenn...

I used Nanopi M1 layout http://wiki.friendlyarm.com/wiki/index.php/NanoPi_M1#Layout to get an idea of Linux gpio numbers to try for the 1x12 headers of my Nanopi Neo Neo v1.0 and Air: http://wiki.friendlyarm.com/wiki/index.php/NanoPi_NEO#Layout http://wiki.friendlyarm.com/wiki/index.php/NanoPi_NEO_A...

Testing revealed that 8 of the 2x12 pins I soldered first were bad. After I fixed a problem with the soldering iron I did fix these pins. And I soldered 12x1 and Debug Uart headers as well. Since I wanted to connect an LCD display, I used a (shortened) row of 40 pin right-angled GPIO headers. There ...

Works with my Nanopi Neo Air as well, after I soldered the headers. Find how to solder 12x1 and Debug Uart headers without collision with LCD here: http://www.friendlyarm.com/Forum/viewtopic.php?f=47&t=383&p=1142#p1142 https://stamm-wilbrandt.de/en/forum/IMG_20161120_134849.jpg Lego blocks a...

I cannot speak on FriendlyArm plans. But the power deck has 8x1.5V reduced to 9V output. NanoPi Neo does need reduction to 5V, so 4xAA batteries should suffice. Hmmm, the 1.39$ 5V battery box I found has 8xAA as well, I ordered it to give it a try. Should easily connect to the 5V and GND pins of Deb...

Wow! The Wiki does not state that the LCD works with Nanopi Neo as well -- but it does! The 24 male pins of Neo suffice for the 26 pin female connector of LCD, the last two seem not to be used. The LCD does NOT fit well, the ethernet connector is too high, the display has to be mounted sloped. What ...

THANK you for this link: http://wiki.friendlyarm.com/wiki/index.php/Matrix_-_2%278_SPI_Key_TFT#Connect_to_NanoPi_M1 Although product page says only for Nanopi 2, that page gives instructions for M1! Just works: https://stamm-wilbrandt.de/en/forum/IMG_20161115_155934.jpg Hermann.

I cannot tell whether that LCD works with M1. I did buy (similar) 10$ LCD from FriendlyArm: http://www.friendlyarm.com/index.php?route=product/product&product_id=102 But I did not read carefully ("It works with FriendlyARM's NanoPi 2"). Not sure wether that can run with M1 ("Its d...

Today I received the Nanopi Neo Air I did order 19 days ago. I wanted to test it directly and not start soldering first. Therefore I took the SD card from one of my Nanopi Neo and inserted into Nanopi Neo Air. I connected the USB2ART connector and powered up the Nanopi Air without issues: (right cli...

Before you connect Uno and Neo the first time, Uno uses 5V logic while Neo uses 3.3V. If you connect them directly, chances are good to kill Neo pins or the Neo. You need a logic level converter, you can get for less than 1$, eg: https://www.aliexpress.com/item/1Pcs-5V-to-3-3V-IIC-I2C-Logic-Level-Co...

Hi, I only once did cross compile the kernel modules successfully: http://www.friendlyarm.com/Forum/viewtopic.php?f=47&t=240#p801 Since most stuff can be either installed or compiled on the board itself I never had the need to cross compile again for Nanopi.

Hi, Thanks for the info. If you can find a way to distinguish nanopi m1 vs nano neo I will add autodetection I do not run Armbian like you, but "uname -n" allows distinction for me, this is for Nanopi Neo: root@FriendlyARM:~# uname -n FriendlyARM root@FriendlyARM:~# And this is for Nanopi ...

This is v1.1, with the new 5 Audio pins on left bottom corner:

v1.0 does not have the 5 Audio pins.

You are in wrong forum here .. M3 is not based on Allwinner H3 but on Samsung S5P6818.
There you should get better help on your question:

I will try what you propose.
But that would degrade the Neo or M1 to a pure runtime CPU with the need to have another 64bit Intel Linux computer for compiling/developing. I like the Neo/M1 being able to develop kernel modules itself as described.

It is good that you show the differences in table USB/Audio/IR Pin Description in Nanopi Neo Wiki: http://wiki.friendlyarm.com/wiki/index.php/NanoPi_NEO There is the Debug Port（UART0) section as well, but for Neo V1.1 the section describing the 5 new Audio pins is missing (currently). Hermann.

Friendlyarm people need to answer the direct question (for Raspberry Pis the answer is that only the new Pi3 is able to boot from USB drive, no other Pi). I once used "plop" boot manager for USB boot without BIOS support (UHCI, OHCI and EHCI) on an old laptop with dead harddisk (plop was b...
