As mentioned before...I am at least layouting an second revision with some bugfixes... Here is a first render of a early Version of Rev2:

I will not use black solder mask this time. I will use some lighter colour (green, yellow or blue). But I had not decided yet.

nice :) what's your fully populated cost of materials?), btw?

the simple Version is ~5€ (including ESP-07). Additional 2€ if using LM3671 and 50 cents for lipo circuit. So the most expensive setup is 7.5€. Including the PCB (1.4€ each) you are at 8.9€ . I never calculated that before. I think under 10€ is not bad.

Awesome :) I'm so looking forward for mine, just because I know that those boards plus ESP and materials are around 5 bugs - I don''t have all that cool lipo and on board usb-serial stuff - but probably use some old usb PSUs anyway. I always keep some cheap LiPo chargers and usb boosters around, that cost me about 1 euro each, without soldering smd parts.
