No, I did not because I read somewhere that it makes debugging with the serial-monitor more difficult.

#55182 Thanks @GRTZ Been awhile since I played with mine and I forgot most everything. Mean while I updated my FT232 device to one from another vendor since the original one was a little intermittent too many times and took a trip. The new FT232RL is the same as you linked to, had to solder the RTS pin and wonder why they put CTS on the bottom connector. I just wish http://smarpl.com/sites/default/files/d ... ce-v01.pdf this had shown IO0 as GPIO0 and IO15 as GPIO15, made me think and that hurt.

#55274 The best way to program and test an ESP8266 201 is using one of these:

http://www.ebay.com/itm/ESP8266-Serial-Wireless-Wifi-Module-Develop-Board-8266-SDK-Development-GOOD-/400914764132?hash=item5d5861d164:g:kH8AAOSwEeFVSeqS

The board has everything you need. Just connect your USB cable and you have the CH340, 3.3V translaters, multiple LEDS, Relay, buzzer, DHT11, switches and buttons to hold down when powering to make Boot Loading easy. They work and they work well. I have 3 of them.

I was even able to take a 201 and remove the 8266 and the EEPROM module and replace them with an ESP8285. It worked fine.
