Hey,
Im absolutely new to eda, i want to design a very compact battery powered esp32 based pcb, one function of it is to power a micro water pump.
The Pump uses 5V with 160mA, I need the ability to (just) switch it on and off using the esp32.
To my knowledge the options are transistors, optocouplers and relays. I have not found a relay small enough to fit my likings, while using transistors and optocouplers in parts seems overkill (but also not unusual for what i have seen). I would really be thankful for some tips and maybe even suggestions about specific models.
