 Sure,

I just ordered to restock my supply:

But simply put

USB TTL

Into your ebay search and you will find plenty of these.  Choose what best fits your sourcing, quantity, delivery schedule, style.

All my arm boards have one permanently installed for console access.  I only need 3 wires:  TX, RX, GRD.

This is why I am upset with the pcDuino Nano Lite in that I cannot get one working on it.  I am actually going to rate this board as a "don't buy" for a server platform becuase of it.  I look at this as a much better way to manage a lot of servers than a KVM box that I use to use with my Intel servers.


Hi Robert,
If you have an image around, you might want to try the Fedora 22 image on the pcDuino3 Nano Lite.

No pcDuino3 uboot in F22.  The only uboots are:

A10-OLinuXino-Lime   beagle         highbank     panda      udoo_quad
A10s-OLinuXino-M     beaglebone     jetson-tk1   paz00      uevm
A13-OLinuXino        cm_fx6         Mele_A1000   riotboard  wandboard_dl
A13-OLinuXinoM       Cubieboard     Mele_A1000G  smdkv310   wandboard_quad
A20-OLinuXino_MICRO  Cubieboard2    Mini-X       snow       wandboard_solo
arndale              Cubietruck     Mini-X-1Gb   snowball
Bananapi             db-mv784mp-gp  origen       trimslice



Before F23 the board had a problem in that you couldn't get the uboot information out of HDMI.  From what I was told it was only going out the serial console.
Maybe with a little tweaking with uboot we can get both HDMI and serial port working.

 
Yes I can and do use SSH a lot, but there are times when things are not working that you want that physical connection.

I also use screen in an SSH session to run a big command, so if I loose my SSH session, I don't have the command prematurely ended. REALLY worth doing on a remote 'yum update'!
