Breadboard power supply module. I create tutorial- style videos about electronics computer architecture, networking various other technical subjects. Did you know that you can connect 2 computer power supplies in series? I will recommend you to use an external power supply, the usual hobbyist “ recycled” 5V/ 700mA USB charger must be more than enough.
Note that all these links are external we cannot provide support on the circuits offer any guarantees to their accuracy. I didn’ t had the chance to measure until now the power consumption of the ESP- 07 module but one thing I can tell you ESP- 01 was a hungry one: 250- 280mA in full WIFI mixed mode, connected transmitting data! You only need to make sure that your DC ground is isolated from earth ground by placing a plastic spacer instead of the original screw that normally connects the PCB to the case. Power supply and power control circuit diagrams / circuit schematics.
The regulator is a TO- 220 package where the Input from the external power supply goes input on the left, ground is in the middle and the 5V output is on the right ( when facing the front of the regulator).
