B.3 Schematic for TOBY-L1 and TOBY-L2 integration
Figure 75 shows an example of schematic diagram where a TOBY-L100-00S or TOBY-L2x0-00S module can be
integrated into the same application board, using all the available interfaces and functions of the modules. 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 relative modules.
