Does anyone know which GIPO on the W90 MCU may have been assigned to the Alarm I/P feature listed in the software?
J11 (2 pins) missing appears to be +12 & Gnd
J2 appears to be a Terminal Port +3V, Gnd, Tx, Rx
No "Alm" or "Alarm" found silk-screened on the board
Missing components sometimes reveal missing features ... here are all the parts that are missing:
PT1 (4 pins)
C80
R32 (Wifi Led)
E3 (2 pins)
R56
J6 (5 pins)
R1
C42
C91
Chips:
MCU W90N745CDG 32Bit Arm Processor with 31 GPIOs
U? IMP1117-033 (3 pins) 3.3 Regulator
U? IP101A Hi Speed Ethernet
U9 ACAA (3 pins) ?
U3 S29GLO32 Flash Memory
U4 ? (5 pins) ?
U? 2952 (8 pins) 5V Regulator
U? W9812 SDRam
