Yes! it can be used for any ESP module as well as an USB-> UART Serial adapter. While only a socket for the ESP-01 module is built in all pins required to program any ESP module are broken out on the programmer so with jumper wires or some soldering you can adapt the DomCo ESP Programmer to work on any ESP module! We've even used it talk to a Arduino Pro Micro directly. Really anything that uses a +3.3VDC UART can interface with the programmer.
We would love to have you as an international backer. Currently we don't have international shipping options because export laws and shipping cost in the US are very complicated and expensive to ship internationally. We got a quote to send a board to London using UPS and FedEx and they quoted us an outrageous price of $25 US. We felt that was a rip off and didn't want to charge customers the same price as the product in shipping cost. We also found that we can ship the boards for about $7-$10 US via the United States Post Office but there is no tracking information and no way for us to guarantee the delivery of the unit to you. Being a small company we didn't want to ruin our reputation by things getting lost or delayed in the mail. For these reasons that is why we are USA shipping only right now.
If you can answer some questions and help me with some information we might be able to get a unit to you. Have you ever backed a hardware project on kickstarter before that shipped from the USA? If so what method of shipping did the product arrive? Would you be ok with the high shipping cost?or would you be ok with a cheaper shipping open and no tracking information if we were to ship boards VIA the United States post office? Any options or answers you have could help us ship internationally and we would appreciate the feedback. Thanks again for your interest. Feel free to message us and we'll do our best.
