How to mount a Pesky Products imp003 breakout board?

[philmond]

I am considering purchasing imp003 breakout from Pesky Products (Kris Winer) with the goal of embedding it on my custom PCB.
What is the mounting procedure: is it a through hole or SMT or something else?
Apparently there are holes but they do not look like a THRU holes.
Thanks,

They are through holes and soldered directly to the board. What type of module are you planning to use ? Are there notches like esp modules ? If so then it’s possible to mount them on your design

Hi Fred,

On the photo it appears as the holes are not through holes but have a
bottom. If they are thru-holes, no problem, I’ll solder in pin terminals
and connect to to my PCB.
I’m not sure what you mean by ‘module’. This Development Board includes
imp003, which is, probably, what you mean by ‘module’.

Thanks for responding and clarification.

Yes , ofcourse they have a botom! They have to act as a spring so that the ESP8266/32 can sit properly and when removed it should goes back to normal state . Therefore I had to make two holes for these pins . One is used for the movement anotner one is for soldering. If these pin doesn’t move you won’t have enough resiliency for connections nor it’ll fit properly.

These pins are specially designed for the ESP module , by module I mean there is a circuitry around the little esp8266 or ESP32 chip . They are carefully soldered on a board with other componates so that you can easily mount them on any breaker board. If you have this type of module in your hand or just google it you’ll see there are notches around the edges of these modules and they are perfect match for these pins.

Hope it helps . Cheers

Hi Fred,
I am not sure if we talking about the same thing.
My inquiry was about

https://www.tindie.com/products/onehorse/electric-imp-imp003-development-board/
https://www.tindie.com/products/onehorse/electric-imp-imp003-development-board/

My understanding is that imp technology is different from ESP. To my
knowledge, ESP is a tiny square with 8*4 contacts at sides.

The mounting holes I am talking about are 13*2 holes along the length of
the board + a couple at the short side. This type of holes seems to be
continuously implemented in various Pesky Products boards.

Does the board in question has anything to do with ESP8266?

Cheers,

Hi ,

I don’t know what others making ，I was just explaining what I’ve created . If you would like to use my pins for your product that’s your choice , how ? Not my problem. There is nothing to do with how IMP or wifi works.

one question though , are you technically asking me to create a board for you ? If so send me the details of your chip, size etc etc … otherwise it’s hard to tell what is what!!

Have fun

Fred,

Are you available for consultancy in PCB design using ESP-12 or similar?

Hi Phil,

Sorry to reply you late. I was not notified for your message!

I am interested. what’s on your mind ?

Regards,

Fred

Hi Fred, it is still relevant.
As a background - for nearly 20 years I am running a small (2-4 people)
innovative software company in Melbourne, Australia. Recently we decided to
move towards IoT. Some of us do have experience in electronics but this is
not our strong point. In particular, we have very limited experience with
SMT.

Our IOT solution appears to have commercial appeal specifically for
Australian conditions.
It is designed for use at remote locations in fully automated mode,
includes 12V SLA battery, solar panel, 4G modem/router and periphery.
Right now we have an advanced prototype version that’s undergoing field
testing - so far quite successfully. We are ready to switch into the
commersialisation mode.

In the prototype we have a thru hole PCB with NodeMcu V3. It is powered via
12V/6V buck converter. 6V @under 1.2A total for peripheral devices is
controlled by ULN2003.

What I am looking at right now:
SMT style PCB + BOM to accommodate ESP-12 with required wiring and 3.3v
supply. We are looking for ordering PCB + assembly from a Chinese
manufacturer Pcbway.com.

PCB design should be in Eagle 2 layers within about 100mmx60mm.
Thermal issues are not critical - the device spends >95% time in deep sleep.

We will use this PCB as a base to add periphery. At this stage we need
flexibility as we have several options for the incorporation of this PCB in
the enclosure.

Kind regards,
Phil
