Suggestions please: ESP8266 "Base"-Board with pyboard Footprint
Re: Suggestions please: ESP8266 "Base"-Board with pyboard Footprint
Oh boy, you couldn't make that routing harder if you tried! But I think I got it. I had to use a bunch of vias, but all should be good.

The gerbers are here: https://bitbucket.org/thesheep/eps8266p ... sp8266.zip

Note that I take no responsibility for this, and make no guarantees about how well this board will work. I did my best in the few hours I had for this, but there may be mistakes. Use at your own risk.

Ah, you will need a HT7333 voltage regulator, four 10kΩ 0805-size resistors, a bunch of pin headers and a micro-usb socket.

Nope, no access within bitbucket, sorry!deshipu wrote:...

Re: Suggestions please: ESP8266 "Base"-Board with pyboard Footprint
I'm not sure, whether you understood what I meant: the pyboard covers all the ten middle lanes (or rows, if you will) of a normal breadboard. See photo:deshipu wrote:The trick is to put the pins in the middle on top, and only put the two rows on the sides on the bottom.SpotlightKid wrote:The Pyboard form factor also isn't very friendly to breadboarding. If you solder male pin headers to it and stick it in a breadboard, it covers all the middle lanes and leaves no place to plug you jumper wires or other components.
Re: Suggestions please: ESP8266 "Base"-Board with pyboard Footprint
Ah, I see what you mean now, sorry, I'm not very used to breadboards -- usually I prefer to use female dupont cables for the connections directly, but that's because I usually work with whole modules, and not individual components. One workaround for this that I have seen is to use two breadboards side by side, but that is of course suboptimal.

Fit the Pyboard with stackable female headers on the long sides, normal female headers at the end. Plug into breadboard. Job done.

I think a version using the ESP-12E, which make use of all the pins exported by this particular ESP board, including the ones on the rear, could be useful too.deshipu wrote:So I used an ESP-12 module instead, which has the same pins, but is much smaller.
Re: Suggestions please: ESP8266 "Base"-Board with pyboard Footprint
I doubt it. Those pins are used for communication with the internal flash memory chip, so unless you are doing something pretty non-standard (like replacing that memory with something else, or using the esp8266 as a SDIO device), they are not useful. In particular, they are not useful while you run MicroPython, which needs that flash memory to run.SpotlightKid wrote: I think a version using the ESP-12E, which make use of all the pins exported by this particular ESP board, including the ones on the rear, could be useful too.
