Показать описание
Notes:
1. Using Arduino Nano act like USB TTL (reset PIN to ground) wont work for me because required external 3.3V supply. ESP keep restarting. Solution you need External 3.3V supply.
2. Using Capacitor for USB to TTL will increase power stability.
3. The latest ESP downloader sofware won't work fro me so I use V.3.3.6.
4. NonOS AT wont work, so I download AT only
5. SET the USB TTL to 3.3V Supply
6. With Arduino I suggest to use voltage divider circuit to convert level 5v to 3.3v
