I know this is an old comment, but in case anyone else is wondering:
Yes, they are polarized. Mic_N is the negative pin for the microphone, and Mic_P is the positive pin, while Spk_N is the negative pin for the speaker and Spk_P is the positive pin. You’re probably going to want to use electret microphones, which have internal preamps, so they have to be connected a specific way. Most speakers aren’t polarized, so it usually doesn’t matter which way you connect them, but if their pins are labeled positive and negative, it’s a good idea to connect them as indicated. Check pages 14-15 of the SM5100B Datasheet for lots of info on hooking up audio inputs and outputs. :)

Thank you guys for being so amazing!
The first time I did anything electronics-y was last May, just after Maker Faire, where I picked up a Getting Started with Arduino Kit. I spent my summer making tv-b-gones, all manner of blinky, loud things, random projects I found online, and a pretty dangerous egg cooker that used big aluminum-housed wirewound resistors as a heating element. I didn’t know what I was doing then, and I still don’t now, but I know that SparkFun is here for me, no matter how crazy I decide to get.
Lately, I’ve been playing with wearable electronics, and my most recent project has been a Tardis hoodie for my boyfriend. It has five little LilyPad buttons on the left shoulder that are connected to a LilyPad protoboard, which can be snapped out when the hoodie is being washed, that I hooked up to a board that was supposed to be in a talking greeting card (reprogramming a greeting card is apparently actually a thing). It now plays Doctor Who sounds. The snaps on the jacket are wired to the buttons with conductive thread. I used a fabrickit ribbon and snaps to hook up the speaker, which is hidden in a pocket behind the “Police Public Call Box” sign. The pockets are heated with some of your 5x15 cm heating pads, and there is a clicky locking button in the right pocket that turns them on and off. A 6600 mAh 3.7v lipo is powering it. Here we are: https://twitter.com/Joey_Hudy/status/416380142575833088/photo/1 :D
Anyway, it is the best thing I’ve made in my entire life, and you guys really empowered me. Without easy access to components – especially sewable components – I probably would have just bought a gift from the store and this great thing would never have come to be. Leah, Dia, and everyone who works at SparkFun are all my heroes. Thank you for sharing your ingenuity with me!
My new project is getting my mom into wearable electronics. She’s been sewing for most of her life, and helps me with designing my wearable projects, but she doesn’t understand any of this electronics stuff yet. I think I’ll get her Sew Electric for her birthday. :)
As a 15-year-old, I’d like to say that more people my age (and all ages, for that matter) need to get into this whole electronics thing – it’s too fun!

These might be some of the coolest things I’ve ever bought from SparkFun. I ordered 24 boards and got 24 Arduino Pro boards, 8 Package Tracker boards, 8 Propeller P8X32A Breakout boards, 20 WiFly boards (Arduino-compatible with a built in wifly module…can’t find it on the website!), 48 little AT42QT1012 capacitive touch sensor breakout boards (also not on the website), 5 Spartan 3E breakout and development boards, and 3 through-hole Christmas tree boards.
Most of the boards are actually multiple smaller boards which snap apart, meaning you might get a lot more than you expect. I was originally planning on chopping all of these up and making jewelry, but I think I’m going to try to populate some of these – at least the easy Christmas tree ones, anyway. The capacitive touch sensor boards are so tiny, I can just stick the earring hooks through the VCC holes and have instant earrings anyway! They’re adorable. The Spartan boards will make amazing coasters. Love it!
No public wish lists :(
