Diode problem in SIM800L module - Arduino Forum
Jun 3, 2017 · So I bypassed the second diode with a jumper and the module turned on with LEDs flashing. The first diode is on the upper side of the board (upper right corner) and the second diode is on the lower side (beside SIM card tray, upper left). The code on the second diode is V1C P628L. My questions are:
