[[PageOutline]] = osmo-nvs-gps = This is a small evaluation board for the NVS NV08C-CSM integrated GPS, Galileo and Glonass receiver. It provides access to the two UARTS as well as SPI and I2C interface of the module, optional backup battery for avoiding cold-start on power-loss and a MCX socket for connecting the antenna. [[Image(osmo-nvs-gps.jpg, 50%)]] == Schematics and component placement == The schematics and component placement files can be found attached to this page. == Part numbers == All capacitors, inductors and resistors are 0603 footprint, with the exception of C1 (0402). * MCX socket is a Tyco Electronics 1-1337581-0 * CR2032 battery holder is a MPD BA-2032 * The 2.5mm jacks are CP-2523SJCT == Jumpers == * J1 connects VBAT with VCC, i.e. should ''only'' be placed if you ''do not have a battery attached'' * J1 connects VIO with VCC. This is the case when VIO (Voltage for digital i/o) is ''not provided by an external circuit attached to X2 * JP4 is the power supply connector. Apply 3.8..6V regulated DC power to it. Center pin is positive, outer pins both GND
