ARM hardware noob questions

I would like to give some helps on the ARM side, I have read some posts (too much, probably i am a bit lost), now time to jump in the water.

Other questions will come with time, first I would like to find a starter kit for developer

rasbperry3+ (following the goal we aim)
power supply (>3A ?)
some sdcards (8GB ?, which speed category ?)
does a fan is needed ?
a matchbox or a box

please add your input please cc @dz00te @mark_nl and all others


Also @rgmhtt could be the right person for your questions.

i was hit by a car while walking sat evening.

right side damaged so am pecking left handed

in rehab unit now to get me walking and then work on dislocated rt shoulder.

at least at week before i can do any testing

fortunately i have email access to this forum, as web interaction needs lots of mousing.

Oh, that sounds really bad, get well soon.

with only sd card, 3A is good

8G minimal try for 16

no fan unless you are in a desert

box is to taste and heat concerns

Whowwww keep you safe !!!

@rgmhtt Best wishes for recovery and hope you get well soon.


  • RPI3+ is a save choice to take a plunge in the ARM world.
  • Usually the (e-)shop also offer the "official" power-supply, because its has decent wires I Can recommend to buy this to.
  • An SD-Card with a A1 (or A2) appliance class approval from a good brand, their names start with an S or a T (1)
  • If the shop offers a cheap heat-sink I would go with it but not a necessity

I tread those little bugs quite bad, they just lie around on my desk never broke one…
but if you are more of cleaned up type, a housing can appeal to you.

Welcome aboard!

  1. Samsung, Scandisk, Toshiba, Transcend

OK…I bought it, I will need a chat on how you think the infra to build the Iso and how to populate the repository



For the single board commuters (SBC = raspberry) flashable images are build with appliance-tools originating from fedora.

Here are the kickstart files used for nethserver-images:

The readme of the nethsever/arm-dev helps to get started
