Less than $3 WiFi chip

Ok. I think it is good as it is now with the exception of jumper. It said that on boot GPIO2 should be pulled to VCC, but it also mentioned that it is done by default, so I guess it is save to leave it unconnected (we don’t have any free pins on U Socket anyways and we do need RST and GPIO0)

So I would only add a jumper GPIO0, GND

Looks good!

couldn’t you change P1 to something more user friendly like Firmware, boot or something since it is a tiny board no need for schematics just to know what is what… don’t you think?

At first I was not using designators, but then I have decided to include them.
I would like either to get rid of them completely (no R1 and no P1 markings) or use them.
But I have already made Gerber files and I have already sent them to @ Architect ::slight_smile:

I was about to press order button and decided to check the forum again. I’ll wait for the change.

Hit the order button :wink:

I think it is good as it is now. And you have ran out of free revisions :smiley:

Alright, ordered!

Is the board public on oshpark?

@ devhammer - I have recommended @ Architect to first order and try this board and if everything turns out to be OK, make it public. But it is totally up to him.

@ iamin wants me to wait before I test it. It will be public.

P.S. If you really want it I can make it public briefly for you (or anybody else) to order. Keep in mind it is untested.

No worries, and no hurry. I am content to wait a bit. I can always wire one of my modules up to a breakout if I need to.

Alright it is public.

I will update description after I test it.

Now that this is done a new challenge! ;D

The first forum member who will put a working full driver on Codeshare (open source) will receive the WiFi module that was just designed by @ iamin with Gadgeteer socket soldered + 10 cm gadgeteer cable + ESP8266

now this isn’t fair as I have the ESP-3 and ESP-2 modules, I feel left out :frowning:

It should work on any of them isn’t it?

In the Adafruit product video, they talk about it using a lot power and possibly needing a regulator (at least in reference to using it with a Trinket 5v micro).

Any issues with power thus far?

It’s peak current consumption is 240mA if I remember right. Regulator is needed if you don’t have 3v3 available.

@ Architect - What are the requirements for the driver?

Thanks - Gadgeteer FTW!

As I coming to work today, I was wondering about this module and EE (as I’m mostly “just” a software guy):

Is there any benefit to using 5v on the socket and then regulating that, as opposed to using the 3v3?

What about downsides, other than just the BoM going up? Increased power (decreased battery capacity for example) draw, due to more resistance in the circuit?
