4.10 Patch Field
A small patch field is available at the LGA DevKit's under-
side. If required, you can add simple components (LED,
Transistors etc.) here. All module signals, except USB and
RF are accessible at the underside by the labeled pads.
4 level shifters are accessible close to the patch field as
well with the reference Vext and Vref. The Vref related lev-
el shifter connections can also be accessed via four addi-
tional pads at the left underside of the LGA DevKit where
additional pins may be soldered (see
Figure 9 ).
Attention: The warranty may be lost if the patch field is sol-
dered.
