Instructions for use

1. Power up the module.

The power supply of the module is made through the terminals with screws marked on the back of the PCB board with GND and 5V. The module also contains a voltage regulator to be able to supply the ESP-01S board with a voltage of 3.3 V.

The relay is switched on when the HIGH logic voltage is applied to pin GPIO0. Also, a red LED is lit when the relay is switched on.

Design prost, risipa de componente

Contra:

1. Contectorii (blocurile terminale) sunt extrem de mici; intrați și ieșiți din releu cu maxim 0.75mmp (conductor solid)
- Am incercat 0.75mmp litat cu pin si nu merge.
- Am incercat 0.75mmp litat si torsadat, dar mai bine nu...
- Intrati si iesiti cu maxim 0.5mmp litat cu pin terminal.

2. De ce au pus un releu imens de 10A?

3. Versiunea mea are si optocuplor THT, dar nu vad la ce e bun pentru ca nu ai decat o singura varianta de alimentare.

4. Distanta dintre trasee (dintre NO si GND) este ingrozitor de mica.

Altele:
- Distanta intre pinii de la blocurile terminale este de 3.5mm si iau in calcul inlocuirea blocurilor terminale.
