Re: Welcome to the IoT forum
Posted: Wed Mar 10, 2021 6:09 amI want to use esp 12f module to control some relays making a smart switch.
I have tried on the esp-01 board and it works. But I understand the esp 12f is not a ready to use board.
Can anyone share a schematic or a circuit diagram or simply pin connection so I can run the circuit.
So far I have made the following connections.
vcc - 3.3v
GPIO 15 to gnd via 10k resistor
CH_PD to 3.3v via 10k resistor
RST pin to 3.3v via 10k
GPIO 0 to 3.3v via 10k
GPIO 4, 5, 12, 13 are connected to a 4ch relay module
GPIO 3, 2, 14, 16 connected to push button.
I have already flashed a firmware and the board boots up and runs but gets reset to factory default every 35-40 seconds. What could be the problem? I feel like I need more components in the circuit?!
