A while back I got my CC2530-based XBee-clone boards back from BatchPCB. Then reality set in—I actually had to solder these things! After much trial and error, I think I finally have figured out the right technique using solder paste, flux, and hot air. Here are some results:

Eventually I'll be running 6LoWPAN stacks on these things and I'll start using them to control things in my house; like light switches, motion sensors, door locks, soil moisture sensors, etc.

Hopefully I can rework all of the ones I screwed up on.
