I just now posted Version 5.
Changes from version 4:
- Uses same inductor as my other Linear Technology based boost converter projects.
- Enlarged PCB board to accomodate the larger design footprint.
-
I just now posted Version 6.
Changes from Version 5: removed or re-arranged silk screen to mitigate potential for solder bridging.

Update: the land pattern contained an error that I didn't notice until I tried to solder the chip onto the PCB. I've now fixed the problem and have now sent revised files to the fab. As with the other projects, I'll wait for the board to arrive and test that it works before I deem it no longer a work in progress.

I've received the board and assembled it (see photo). It appears to work in accordance with the datasheet. Therefore, this project is finished.

Is a schematic available?

Yes. If you look in the photos section, it's there. It's the same as what's in the datasheet as a "typical application."

Hi. Do you think this will be enough for indoor usage to power a simple temperature sensor ?
What type of battery did you use this module with ? -
First time SM assembly. Photos do not show connections to 3 tiny holes that must go to ground. Is this done with small wires to side holes on either side or ...?
@mar The three tiny holes may not go to ground. They are probably 'vias' that take a trace from one side of the board to the other.
Vias are through plated at manufacture and shouldn't need anything from you.
But I don't know this particular board and so things might be different here. Use a multimeter to check the circuit diagram against the board.
