When I designed first versions of Bee, I mostly used Sparkfun Eagle library, as an habit, and browsed eBay on the other side in order to choose components: one that’s available in Eagle and cheap enough on eBay. By this time, I selected a microSD socket Push-Push type:
These were easily found on eBay, at a decent price, I ordered 5pcs (~$5). Since then, these aren’t available anymore, alternatives sources are much more expensive, something like $3 to $4 per socket. This somewhat kills my low cost approach… Another drawback is pins are under the case, which make this part hard to solder, probably the most difficult one.
