The power connector on the 703 is a standard micro USB, so you can use anything you like to power it, like a phone charger. Got mine delivered from HK to the UK for £17.
As an aside, the power supply that comes with it is rated for 100v to 250v so you can use it pretty much anywhere, if you have the right adaptor.
Yup but I bought mine for £16 including the power adapter, Golden Computer Arcade FTW ;-). In retrospect I should have haggled but then they can see me coming and I have zero cantonese. Next time I'll try to rope in a guy from the office to help me bargain
I'm looking at the wiki page for MR3020 and it looks like the latest snapshots support it, so I guess that means this firmware could be used with it? I'm really kicking myself now but I found 10+ places selling the MR3020 and only one selling the 703n and the box wasn't sealed which worried me too. Just my luck I could probably have mail ordered from the UK now it's more popular. Anyhow, I'll get on the case and fire up a dev VM with the build env when I can. Looking enviously at all these people talking about flash/RAM upgrading but I'll probably just get a raspberry pi for that. I'm totally happy running a fully distro but lack experience in embedded.
