A.3 Schematic for TOBY-L1 and TOBY-L2 integration
Figure 85 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.
