SparkFun SIM Card Socket BreakoutSparkfun
This is a full 8-pin breakout for the SIM socket allowing direct access to SIM communication.
Note: This breakout board was originally designed for a SIM socket with a switch for card detection. We have since switched to a socket that does not have this feature so the SW1 and SW2 pins have nothing to break out and can be considered NC. The 6 SIM card pins, however, are still broken out correctly.
