About £2.80 for a nano with a cable. Cheap. People probably pay about 5 or 10 times that just for a USB cable in some shops.
Things I have ordered so far:
2 nanos
4 wireless transceivers
1 real time clock
2 temp sensors
One more question (for now): I can probably get my hands on quite a high capacity 18V Li Ion battery from an old cordless drill.
How could I use that with an Arduino. External voltage regulator or sommat?
Most Arduinos can take 6-20V on the Vin so you shouldn't need a regulator (there's one onboard).
Both my SainSmart and the nanos say up to 12V.
Had a quick look on Google. Depends how much current the board will be consuming. If it's not doing too much it should be ok with the 18V, otherwise it would need another regulator that could handle tthe current.
A quick question about the mini boards: what cable is required to program the board? Is it just a cable or is there a circuit board between the two?
I might buy an 8MHz mini to make a custom transmitter to use my Taranis controller with my Hubsan X4.
The Pro Minis (without USB) need a USB to Serial (FT232) adapter of some sort to program them.
Because my adapter doesn't have the correct reset pin or something like that it's a pain to use, I've got to reset the board at exactly the right point to get sketches to load.
Much obliged once again Anthony. I'll have a look at that video later. Too many things I want to do already that I don't have parts for.
