how much NodeMCU GPIO Current Maximum, and NodeMCU standalone Power Consumption?
<p>Unfortunately, i can't find hardware Spec about NodeMCU.</p>

<p>so i want know about GPIO Current limitation, Standalone Power Comsumptionm, and board size.</p>

<p>or Can you share the link about NodeMCU Hardware Spec?</p>

<p>some page say that GPIO Current Maximum is 12mA, but I can't find any Confidently say. </p>

<p>Thanks.</p>
