Build custom shield?

Postby nardev » Thu Jun 01, 2017 6:07 am

i'm looking for some kind of guidelines how to build a custom shield for ESP8266.

So far, i have functional prototype build with NODEMCU but i wan to simplify things now and make it smaller.

1. Is there some written, open hardware guidelines for that
(good example, blog post or youtube video speaking about experiences, would be good enough)

2. Is there someone who would be willing to make it or help make it and be payed for that?

You have to follow the same good design practices that you would follow when designing circuits for any moderately fast MCU (such as ARM7). The trickiest part with ESP is the RF section. If you do not have a network analyzer and RF simulation software, designing and testing antenna may take multiple trial-error attempts before you get it correct.
Some links for RF antenna part: ... iderations
If you need external help you may contact on the below links.
If you do not want to mess with RF section, you may want to use modules like ESP-12 or ESP_WROOM_02 modules for making your systems. That is usually the simplest and fastest way.
