A.3
Schematic for TOBY-L1 and TOBY-L2 integration
shows an example schematic diagram where a TOBY-L1 series module or a TOBY-L2 series
module (“00”, “01”, “02”, “03”, “60” or “62” product versions) can be integrated into the same
application board, using all the available interfaces and functions of the module. The different
mounting options for the external parts are highlighted in different colors as described in the legend,
according to the interfaces supported by the different module product versions.
