{{WarningMessage|text=By default, BoraXEVB comes with a Zynq 7030-based SOM. However, it can host different models of BoraX SOM. From the point of view of PL's I/O voltage levels, different models may not be equivalent. Please refer to [[#PL's I/O voltage selections|this section]] to avoid unsupported configurations that '''may damage the hardware permanently'''.}}

===BoraXEVB voltage selection jumpers===
BoraXEVB provides several configuration jumpers that allow to easily select the voltages used for PL's I/O banks. The following tables lists some of the allowed combinations used to select the most common voltage values. There are other combination available. However, '''some of them are not allowed and may cause permanent hardware damages to the Zynq part'''.
Since characteristics of PL's I/O banks differ between Zynq 7015 and 7030 parts, the valid combinations '''are not the same for all of the BoraX models'''. Please refer to the following sections for more details.
JP32:Even if PL's banks are independent, default configuration of BoraXEVB is such that*bank 34 and bank 35 have the same supply voltage*this voltage is selected via JP28.This configuration is in accordance with default routing of signals used for FMC connector.====Examples of valid combinations for Zynq 7030-based SOMs (default option for BXELK)===={| class="wikitable" style="text-align: center;"|+Bank #13 (HR)
