There are two base board supply-voltages VIOTA, VIOTB and for the 4x5 SoM's PL IO-banks. The supply-voltages have following pin assignments on B2B-connectors:
base-board VCCIO | base-board B2B connector-pins | standard assignment of PL IO-bank supply-voltages on TE 4x5 modules module's B2B connectors | base-board voltages and signals connected with |
|---|---|---|---|
| VIOTA | JB2-2, JB2-4, JB2-6 | VCCIOB (JM2-1, JM2-3) / VCCIOC (JM2-5) | HDMI_SCL, HDMI_SDA, HDMI_INT, J5 VCCIO |
| VIOTB | JB1-10, JB1-12, JB2-8, JB2-10 | VCCIOA (JM1-9, JM1-11) / VCCIOD (JM2-7, JM2-9) | VCCIO1 (Systm-Controller-CPLD pin 55, 73) |

Note: The corresponding PL IO-voltage supply voltages of the 4x5 SoM to the selectable base-board voltages VIOTA and VIOTB are depending on the mounted 4x5 SoM and varying in order of the used model. Refer to SoM's schematic to get information about the specific pin assignment on module's B2B-connectors regarding PL IO-bank supply voltages and to the 4x5 Module integration Guide for VCCIO voltage options. |
Following table gives the conjunction between the base-board supply-voltages VIOTA, VIOTB and the PL IO-bank's voltages of 4x5 SoMs:
supported 4x5 SoMs vs base-board VCCIO | TE0710 | TE0711 | TE0712 | TE0713 | TE0715-xx-15 | TE0715-xx-30 | TE0720 | TE0741 | TE0841 |

Following table describes how to configure the base-board supply-voltages by jumpers:
base-board supply-voltages vs voltage-levels | VIOTA | VIOTB | USB-VBUS | 12V0_CL |
|---|---|---|---|---|
| 3V3 | J17:1-2, 3 & J16: open | J17: 1-2, 3 & J16: open & J21:1-2, 3 | - | - |
| 2V5 | J17:1, 2-3 & J16: open | J17:1, 2-3 & J16: open & J21: 1-2, 3 | - | - |
| FMC-VADJ | J17: open & J16: 1-2 | J21:1, 2-3 | - | - |
| 5V0 intern | - | - | J9:1-2, 3 & J19: 1-2 (J20: 1-2: additional blocking-capacitors) | - |
| Vbus extern | - | - | J9: 1, 2-3 & J19: open | - |
| 12V_LC | - | - | - | J18: 1-2 |
