Circuit Board Design
$30-250 USD
Paid on delivery
My project consists in a circuit board which is responsible for
communicate with the internet and triggering 4 electronic locks of 3V 1.5a using relays.
Due to high inductance generated by the electronic locks, it is necessary that the
circuits of the locks are isolated from the microcontroller circuit to avoid crashes/bugs.
The board must have a circuit of lithium battery which must provide an autonomy of at least 8 hours.
This circuit will be activated when the site is without power.
To connect the ESP32 to the internet, a 4G modem is connected to the board.
The board must have a female USB connector to power the 4G modem.
The female USB connector must have a circuit capable of having its power interrupted by a command
sent by an ESP32 I/O port (After a few hours of initerupted use the 4G modem loses its internet
connection and it is necessary to turn it off and on to get it working again.
