*While choosing the relays you need to power the board with the same DC voltage or get an smps that will full-fill the needs range supported is between 12v and 5v
PCB board view
- Firstly disconnect any load that is connected to the relay
- Now power the board via AC or DC (DC recomended)
- connect the Rx of the usb to ttl converted to Tx
- TX of the converter to the Rx
- GND of the converter to GND of the module
- Press the Push Switch once to enter programming mode (a relay will click)
- Then press the reset switch once
- After this you should be able to program the ESP-01 S using the module
- After programming you should Press the push button and reset switch so that ESP-01 S can run the code
- Async Webserver for ESP 01 S is a firmware that allows the board to be controlled through WiFi by using a Web interface.
- ESP 01 S Automation using MQTT is a firmware that connects the board to MQTT broker and allows the board to be controlled from anywhere.
- Download and extract the git-hub file
- Find the Board Gerbers form the Gerber folder
- Now upload the gerber zip file to you pcb manufacturer (JLCPCB recomended)
- Now you can place the order
Once the pcb arrives then you will need to cut it along the guid which is on the pcb this will give you two coppies of the board
Additionall if you only want to power the board with DC power supply then you can skip mounting the smps and directly power it with the DC jack or else you can cut the hilink smps section of the board (this is optional)
- Module is well suited for automation systems
- Well suited for space constraint areas
- Easy to Program and develop solutions that require automation
- Provides a cost effective solution
