Typical power consumption for TE0703-05 + TE0715-01 module with SD micro card inserted, Ethernet connected

and link up, system booted into Linux prompt and idling is 5V / 0.55A.

4.3 Power-On Sequence

It is not allowed to feed any voltage to any external I/O pin before there is no power indication on M3.3VOUT pins.

Presence of 3.3V on B2B JB2 connector pins 9 and 11 indicates that module is properly powered up and ready.

If any of the VCCIOA, VCCIOB, VCCIOC or VCCIOD will be powered through external connectors J1 or J2, then

corresponding VCCIO jumper should also be removed altogether, see next chapter.

4.4  VCCIO voltage selection jumpers J5, J8, J9 and J10

Refer to the 4x5 Module Integration Guide for VCCIO voltages options.
