Table 7: Pin-out of the 42-pin Dual-In-Line Board-to-Board connectors (J301, J300) available on the adapter board ADP-R2
of the EVK-R2 evaluation kit for LARA-R2 series modules
☞
The pins / interfaces that are not supported by a specific LARA-R2 module product version should
not be driven by an external device (see the LARA-R2 series Data Sheet
and the LARA-R2 series
System Integration Manual
for the features supported by each LARA-R2 module product
version).
