Esp12-e DUAL "Form C" Relay + 4 binary inputs + Power Regulator

Designed to fit inside standard electric wall boxes

Primarily for WiFi home automation retrofitting lighting controls

(2) independent Form “C” relays,
rated 125Vac/3Amps, on GPIO 4 and GPIO 5
connectorized to #14 ga. wire screw terminals

(4) binary switch inputs
with 10K pullup resistors, on GPIO 12, 13, 14 and 16
switch wire pairs connectorized to RJ48 jack
using standard TIA568B color code-
Blu/White = GPIO 12
Org/White = GPIO 13
Grn/White = GPIO 14
Brn/White = GPIO 16

Efficient 78SR3.3 switching power regulator, 7.5 to 36Vdc
connectorized to a standard 2mm BARREL style plug

I think this is the unit I will be installing in my new home.
It’s exactly what I want-
I’d rather run the +12DC to each wall box-
knowing that every device connected will have UPS/battery backup.

If I line-powered each unit, then, if a bad guy cuts my power, -they can rob me.
I’d rather have central battery/power distribution. Like a burglar alarm and ancillary devices.

Time to whip-up (27) of these devices! (9 PC boards X 3 units per board)
(Newer video to follow, I will show assembly/construction of the unit)

I’m thinking- in MANY of my needed applications- the Sonoff device will work perfectly- like, on a simple light switch-

-and I just CANNOT beat the Sonoff price!

I JUST got all my parts from Digikey!
Yaaaay!
The new PC boards will be arriving probably on Tuesday.

I got BOTH the Solenoid8 AND the Avonelle!
$135 for:
(3) Avonelle boards (X 3 = 9 Avonelle units)
and
(3) Solenoid8 PC boards (X4 = 12 Solenoid8 units)

My engineering goals have been met!

Perfect!

I just got my PC boards for Solenoid8 AND Avonelle!
