Missing info and links in ESP programmer assembly guide #144

Closed danboid closed 2 months ago

danboid commented 2 months ago

I would like to build the ESP programming jig so I referred to the BOM in the jig assembly guide:

https://github.com/Uzebox/uzebox/blob/master/schematics/ESP-12F-Programming-Jig/V2.1/assembly-guide.md

The first bit of info I noticed that was absent is the pitch of the FTDI 90 degree header, which I presume is 2 mm?

We should also update the jig assembly guide to include links to at least one vendor for each item required.

It seems we can probably use DigiKey Part Number 17-2314878-8-ND

https://www.digikey.co.uk/en/products/detail/te-connectivity-amp-connectors/2314878-8/11502809

for the 8 position female header, 2mm pitch.

Where did you buy your Uzenet friendly female headers from @uze6666, if it wasn't the one I've linked here?

As for attaching a ESP 8266 to a Uzebox PCB using header rows I presume this could be used:

CONN HEADER VERT 8POS 2MM - Digikey 952-2278-ND

https://www.digikey.co.uk/en/products/detail/harwin-inc/M22-2010805/3728242

This or something like it is currently missing from the jig BOM, but maybe it makes more sense to add it to the Uzenet section of the Uzebox BOM instead?

The FTDI header pitch and links are in the BOM file already in the repo here:

https://github.com/Uzebox/uzebox/blob/master/schematics/ESP-12F-Programming-Jig/V2.1/esp12-prog-jig-V1.2.BOM.txt

I think at least the pitch should be mentioned in the assembly guide, if we don't add all the links too. Why not?

I've not read the guide in full yet. I won't read it properly until after I get all the parts and try building a ESP programming jig.

for the 8 position female header, 2mm pitch.

This costs twice as much as the one listed on the jig BOM so nope.

All the required parts are indeed listed in the BOM file. The 90 deg header is 2.54mm pitch and the 8 pins female one is 2mm. For nw I prefer to keep the bom separated, it's easier to quickly browse for the part numbers instead of going through the assembly guide, I have update the guide to refer to the BOM and added the 2.5mm mentioned on the 90deg header.

Fair enough. I'm going to close this now.
