The connections to an ESP8266-03 are similar to the ones shown here http://www.benlo.com/esp8266/esp8266QuickStart.html ?? GPI0 to GND and so on...

Yeah, you'd better search the forum for esp03 though.

These schematics are made with the ESP8266 facing up (chips visible) or facing down?

Chip up. The esp-12 is still wrong, btw.

Also depending on your computer, the tools for flashing vary, also if you need to flash a 2MB module (such as the Olimex one) then you need to use certain tools.

What special tools are necessary for this board (the Olimex MOD-WIFI-ESP8266-DEV)? I am just getting hints to use the default toolchain and those sparse docs from Olimex to let the board enter UART mode. It does not work and i simply seem to fail while trying to let the board enter this mode.

What i try is to pull pin 21 to GND while powering the board. This is what i think i need to do while reading the Olimex schematics. Sadly the esptool.py can not connect to it

Any clues?

The Olimex MOD-WIFI-ESP8266-DEV has to be programmed. I have successfully loaded nodemcu lua into one using the flasher tool available at https://github.com/nodemcu/nodemcu-flasher.
Cycle the power on your board with GPIO 00 tied to ground , select the com port on the flasher tool and
press flash. When complete, cycle the power again with GPIO 0 floating.

A good piece of software to use with lua is Esplorer available here http://esp8266.ru/esplorer/
