To install the ESP32 board in your Arduino IDE, follow these next instructions:

- From Arduino IDE:?***File***?->?***Preferences***

- In the Additional Boards Manager URLs add this link (if you have more than one link, separate them with a comma):?<https://dl.espressif.com/dl/package_esp32_index.json>

- ***Tools***?->?***Board***?->?***Boards Manager…***

- Search for ESP32 and press install button for the "ESP32 by Espressif Systems"

### <https://github.com/maximealive/TelegramBot_ESP32-W5500#upload-sketch>Upload sketch

- Select your board from:?***Tools***?->***Board:"xxxxx"***?(I selected "ESP Dev Module")

- Check the upload speed from:?***Tools***?->?***Upload Speed***, should be 921600

- Upload the sketch

- Be sure that when the upload finishes you can see something like this:

### <https://github.com/maximealive/TelegramBot_ESP32-W5500#notes>Notes

- Before use an external power supply (5.0V-0.7A) I tested the circuit connecting both the relay shield and Ethernet shield to?*Vin*?pin of the ESP32 and all the ground together, with the ESP32 connected to the PC through the micro USB cable.

- To use relays I used specific pins because some of them are HIGH at boot and this could cause problem ***

- Any suggestions are welcome

### <https://github.com/maximealive/TelegramBot_ESP32-W5500#to-do>To do

- Add power management

- Add option to use WiFi if the Ethernet isn't working in that you can do a WiFi hotspot and continue to use the bot being near the shield
