I want to connect HC-04 ultrasonic Vcc pin to a GPIO pin to control sensor on/off. HC-04 working current is 15mA. Can GPIO pin on Heltec Wireless Stick Lite provide that current to HC-04?
I am doing this because I want to put Heltec Wireless Stick Lite in deep sleep and also save power not connecting HC-04 directly to the battery.
Thanks for help
