That's not good for either the power supply or the module. The power
supply might take damage from the overload (although good linear
regulators should have various shutdown mechanisms.) It's also not
good for the module since transistors (including those in ICs) have a
tendency to break down when you apply a reverse voltage. Definitely
watch out for weird behavior in the future.
