Micro Crystal RV-3032-C7 Development Board
Micro Crystal RV-3032-C7 Development Board is a demonstration board for the RV-3032-C7 Real-Time Clock Module with I2C Bus. Micro Crystal RV-3032-C7 is soldered onto the development board. Every pin is accessible at test pins 1 to 8 and at the test vias situated around the device. The eight top-right vias (one-one copy of the test pins 1 through 8) can be used for an angled connector. RV-3032-C7 Real-Time Clock Module with I2C Bus incorporates an integrated CMOS circuit together with a crystal (XTAL).
