The suggested design is not meant to be friendly to your bread's board. Only for your budget, hand soldering and field usability.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. The huzzzah/nodemcu form factor is much more practical in this regard.

sorry, i did pick roberthh's post regarding this.Turbinenreiter wrote:...feather...
This might be a take to change it. The design by itself it smart in my opinion"Also, in choosing boards to be Pin compatible with, why the pyboard? The form factor didn't exactly catch on and there is next to none expansion boards for it.
To be honest i did get some WROOM-02s for cheap money and want to use them.Adafruits Feather form factor however has a whole lot of expansion boards. Why not just use their Huzzah boards?
'cause i will not install Eagle... could you please provide an export as an bitmap or vector file format?If you wanna drop cost, the Eagle files for that board are Open Hardware and it could be easily modified (I'm willing to do that - edit: I just did, it takes like two minutes to remove all the parts you don't want. An hour to check and recheck everything and it's good to go. Checkout here).
No, thanksYou guys just need a crash course in Eagle
All constructive answers are welcome!(Not trying to 'shit' on your idea, just trying to provide constructive feedback.)

Cool, thanks. But it should be possible to fit it on a board of that size...deshipu wrote:So I tried to make a quick and dirty mockup of such a PCB in Fritzing (http://fritzing.org). The first problem I had is that the WROOM-02 board is too wide to fit between pyboard's pins....
Re: Suggestions please: ESP8266 "Base"-Board with pyboard Footprint
Hmm, ok then, it seems that the footprint of it that I found was wrong. No problem, we can just use 2mm pitch pin headers in that place, and solder the module to that.
The real problem is which gpio pins should go where. Any ideas? I can update and clean up the design then.

Check the attached screenshot from their datasheet... It is a 1.5mm spacing i'd say.deshipu wrote:Hmm, ok then, it seems that the footprint of it that I found was wrong. No problem, we can just use 2mm pitch pin headers in that place, and solder the module to that.
I am working on this right now.The real problem is which gpio pins should go where. Any ideas? I can update and clean up the design then.

I think your claims about Eagle are beyond ridiculous.kfricke wrote:'cause i will not install Eagle... could you please provide an export as an bitmap or vector file format?
Fritzing is nice, but way to limited. KiCAD is the best you can get free of charge and it also is free as in FLOSS. But Adafruit uses Eagle so when I adapt a design I have to go with that. KiCAD is also way harder to use for a beginner because it's library management is designed for hardcore pros, Eagle is way more convenient (but also a shortcut).
VBAT is connected to an ADC via a voltage divider, so there is the possibility to track voltage.kfricke wrote:Why do they design a LiPo "subsystem" without the possibility to track voltage.
I think the idea of a low cost and DIY friendly ESP8266 board using the Feather form factor is viable and I will keep on working on that. There are some more parts that can be removed and others that can be replaced by through hole parts.
Re: Suggestions please: ESP8266 "Base"-Board with pyboard Footprint
That is wrong as far as i know. Do you see it on their board design files? Their learning system tells to solder up that voltage divider by hand.Turbinenreiter wrote:...

How do you think it is implemented? Is it switchable?
Very interesting anyway. Please keep me updated. I do also like the feather form factor.I think the idea of a low cost and DIY friendly ESP8266 board using the Feather form factor is viable and I will keep on working on that.

The recent free version of eagle do include advertisements reloaded from the web. The embedded ads can in fact spy on you and thereby can considered spyware or malware.Turbinenreiter wrote:I think your claims about Eagle are beyond ridiculous.

You are right, I just saw it, too. The M0 Feathers have it onboard and I thought all of them do.kfricke wrote: That is wrong as far as i know. Do you see it on their board design files? Their learning system tells to solder up that voltage divider by hand.

Just updated the branch with a through hole part design. You can use http://forest.rivc.co/hackmit/ to view it without using evil Eagle.kfricke wrote:Very interesting anyway. Please keep me updated. I do also like the feather form factor.
