ESP8266-03 Wifi Board

Day 2 – I have come to the conclusion that I need a level shifter. Ordered 2 from Cali. Hmm, investigating using a usb-serial cable with a 3.3v ps. http://playground.boxtec.ch/doku.php/wireless/esp8266 has German instructions. Giving that a go. Scratch that, I think maybe I blew my ESP8266, I had it hooked to the USB-Serial cable without a level shifter for some time. I did try a resistor voltage divider, but get no response. I will have to try another board, I have to solder it up. I did find some really good beginner instructions here: http://www.esp8266.com/viewtopic.php?f=11&t=521#p3110

Day 1 – Soldered some resistor legs to the SMT spots. The method I used was to insert the snipped legs from the resistors into a 16 pin dip socket, then wedged the board in place. This had the effect of getting the pins to be held against the board. This is the final result. I have not found any helpful links about this version of the board yet.
