!!! cool !!!
Yes, there is enough current to hold the 433 receiver from the arudino output. I'm switching it on every 4 seconds to receive a remote push signal and only if i recognize one, I wakeup arduino from sleep. The capacitor near it is relatively new and I haven't implemented it in the real world yet, today it's without this capacitor. I do have a working pcb of the whole project for around 10 month with 4 18650 batteries.
