A16 and HC-SR04

[MnM]

Hi,

I have an A16 board and I will like to add 2 x HC-SR04 devices to it.

I understand how to configure the pins in ESPHome so all is good on that side.

My question is more the electrical part - the HC-SR04 units require 5v each.

On the A16 schematics I cannot see anywhere where that outputs 5v.

I see in another thread (https://www.kincony.com/forum/showthread...ht=HC-SR04) that the  433MHz receiver data pin on PCB produces 5v - is that the middle PIN that produces 5V?
And will I be able to power 2 or more (4?) x  HC-SR04 units from it?

Thanks.

Yes, 433M receiver have pin with 5V. i think if 2pcs of HC-SR04 should be OK, you can test.
