Can anyone tell me roughly how much current the WRL-11373 draws? I've googled and looked on Sparkfun but can't find any info on it. It says here that the max supply current is 500 mA.

enter image description here

Figure 1. The module 5 V to 3.3 V regulator. Source: XBee Regulated - V14.

The 500 mA specification is the maximum the board can supply at 3.3 V, not what the board itself consumes. This is determined by the MIC5219 voltage regulator.

Actual consumption of the board will be the tiny current required by the level shifters (if I understand its function correctly) and whatever the board is feeding at 3.3 V.

  • \$\begingroup\$ I'll be using the XBee Explorer Regulated to power/control an XBee Pro S1 which consumes 55 mA. So I would add this to the level shifter current draw nA or μA? \$\endgroup\$ – somers Dec 30 '18 at 16:08
  • \$\begingroup\$ So your board will need a 55 mA supply then. \$\endgroup\$ – Transistor Dec 30 '18 at 16:11
