The Photon Datasheet is here:

Woo hoo!!! Nice job @BDub!!!
Great work here laying everything out!
There seems to be a really big discrepancy between what was measured above for deep sleep power draw (60uA) and what is in these specs (160uA).
Can we get some help understanding the discrepancy? I thought the new voltage regulator was way more efficient? How is the electric imp 25uA, but the photon misses the mark by so much?
See attached https://github.com/spark/docs/issues/307 that shows the 60uA number. Has there been an error in the published datsheet? @BDub @Dave
@BDub I still see the big discrepancy between the github posted measurements and the datasheet published for deep sleep current draw. Can you please share why those numbers are so far off?
@HardWater and @mashandburn yes I can clarify. The numbers posted in github are from 1 of a handful of hand built photons, and come with a disclaimer. I chose to error on the conservative side of the spectrum for the datasheet until more info can be gathered from a larger sample of production photons. Thanks for hanging in there! Also, if this info is really crucial for a large number of products you are developing with photons, please PM me about your needs and Iāll try to readjust my priorities accordingly.
Thanks a lot
Any idea when is the Photon datasheet going to be available? If it is somewhere please links
With great difficulty, I was able to extract an (English) datasheet of the BM-09 module from a Chinese forum a couple of months ago. . .but thatās not the Photon module with all the associated circuitry.
Would you happen to have a link to the BM-09 module datasheet? Iād wish they would also have the datasheet for the module here. With most development boards the uC datasheet is available from the supplier, but in this instance there isnāt one at least directly available from the website.
Would these new docs be of any help?

Sure that is helpful, but Iād like to find the BM-09 datasheet somewhere. Like STM32F205 datasheet, but is that valid for the BM-09 and also what the pins are etc. I would like to study it.
I emailed the company asking for itā¦ letās see what they answer. Meanwhile Iāll google, but official source is always better.
OK found this: If you use this it is not my fault if something is not correct
@FistOfTheNorthStar I think thatās the datasheet I found, and itās from a Chinese website. Preliminary and allā¦authored by Tsai Jason (PDF document properties), 24 pages, 1.25MB?
If youāre doing PCB layout in KiCad, Iād be happy to share the footprint I made for it. Deciphering the footprint diagram was a bit of a challenge, but I did succeed.
You can also use the Photon moduleās PCB layout as a guideline to answer any questions (as that obviously works): https://docs.particle.io/datasheets/photon-datasheet/#schematic-p-wi-fi-module
@Moors7: Hoorayāthe new docs! Waiting for the new Core firmware
ā¦
That would be awesome!
@FistOfTheNorthStar: What would be awesome? KiCAD footprint, or the new Core firmware?
KiCAD footprint
@FistOfTheNorthStar: Here you are: A ZIP file containing the EEScheema definition (DCM, LIB), the PCBNew definition (kicad_mod) and the 3D model (WRL).
For EEScheema, youāll need to import the LIB fileāI just exported the footprint from a library, actually the system āMicrocontrollersā library. For PCBNew, I had a separate project library with the KICAD_MOD file inside; the KICAD_MOD file references the WRL 3D file. I hope you can figure this out!
EDIT: FWIW, the pin references in the EEScheema model on the right side as as follows: STM32 CPU pin name / extended function name / Photon pin name.
Who made this awesome interacvtive datasheet for the Photon. Was that you @rickkas7 ?
Yes, that is mine, from a long time ago. I donāt think I ever posted a link to it here!
I guess I should finish it and add in the Electron pins now that the secret is out.
