Elecrow ESPduino how to?

Hi

I have here on the table a Elcrow ESPduino
http://www.elecrow.com/wiki/index.php?title=Elecrow_ESPduino_UNO%2BESP8266_Wifi_Board
Its connected via COM7

I can't figure out whith type of board is needed in the config to send a sketch to it.

Any hint?

Peter

The link describes it as an Uno.

PS
There seems to be a jumper pair to select the serial communications between the 328 and the ESP; while uploading, do not have it set to use hardware serial as that might interfere with the upload process.
