PB0 (TX) pin emits negative voltage #65

Closed platisd closed 6 years ago

platisd commented 6 years ago

Description

PB0 has been measured to emit negative voltage (when it should be steadily at 0V with the current firmware) which results in a weird ~1.0V value being supplied at the wifi module even when it is off.

A workaround for this is to bend (not connect) the RX pin of the WiFi module.

Definition of Done

Root cause of this strange behavior is identified and a fix is issued.
