The SIM9B1 and SIM9B2 prototyping kits offer users a convenient path to integrating custom circuits into an existing SIM900 Mainframe system.
SpecificationsInterface: Serial (RS-232) via SIM interfaceConnectors: DB15 (male) SIM interfaceDimensions: 1.5" × 3.6" × 7.0" (WHL) SIM9B1, 3.0" × 3.6" × 7.0" (WHL) SIM9B2Weight: 1.2 lbs. SIM9B1, 1.4 lbs. SIM9B2Warranty: One year parts and labor on defects in materials and workmanship
The SIM9B1 is a single-wide blank module, and the SIM9B2 is a double-wide blank module.
The exterior mechanical interfaces for both sizes are fixed.
In their as-delivered form from the factory, these are immediately usable as empty-slot fillers for the SIM900 Mainframe.
For users wishing to populate these with custom circuits, the module hardware has fixed mounting points for holding the board and the DB-15 connector.
