Description: Electronic Components Development Board Module SIM Card Socket Breakout. This is a full 8-pin breakout for the SIM socket allowing direct access to SIM communication. 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. Specification: Material: Plastic Color: Multi-color Size: Approx. 31x27x4mm/1.22x1.06x0.16inch Package Includes: 1 piece Breakout Module Note: Pls allow an error of 1-3mm due to the difference of manual measurement
