IOT - ESP8266 Dual Relay Module Controller Shield

Testing BLK BOX 4 layer ESP board to take advantage of it's onboard U.FL connector for external antenna mounting on my solar controller enclosure, its pins are the same as the ESP-01 with the exception there are two more IO's added on one end for GPIO12/ADC (jumper selection) and GPIO14

Voltage Checks:

NPN1 Gate (gpio0) = 2.6v

NPN2 Base (gpio2) = 3,2v

Relay output pin from NPN1 = 0.0v

Relay output pin from NPN2 = 2.7v

So far the change to NPN1 has passed bootup and allows it to connect to my AP ok

I'm not sure if my codes right as the buttons arent doing anything when i turn them on/off , also the NPN2 circuit seems to be always triggering its relay where the NPN1 one wont (code maybe or R6 vaue)

NPN1 using the 2N222A was triggering flash mode on boot, with some troubleshooting help from member SUF here. I Swapped it out for a pin compatible BS170 N channel mostfet

"the MOSFETs Gate is insulated from the Drain-Source channel,

and not acting like a clamping diode"

Schematic Changes:

Theres a Code or resistor value discrepancy for the GPIO0 for reset

when I remove R3 (1K) to disconnect the transistor for relay output the board boots and connects to the AP Correctly ,so its either the code or a resistor value

Considering adding a diode for output only on the R3 Trace so it doesnt see anything from the transistor side

Testing seems to be ok, 5v and 3.3v are spot on, but its not connectiing to the AP but will with just voltage supplied & reset works as intended

I think the code needs to set the gpio high so it doesn't enter flash mode on startup besides that so far so good

First Board Assembled - Testing to follow

The oshpark order arrived - assembly started and shipping out Vlad's board for testing

Oshpark prototypes shipped last week might arrive next week for some testing before final revision submission on next run
