ESP12-E-DEV Protoype Shield
In answer to quite a few requests for a prototype shield, similar to my ESP32-S Dev Prototype shield, but for use with the ESP-12E DEV board, I have decided to do a quick design, and make it available publicly
This is the MakerIOT2020 ESP12E-DEV Prototype Shield. It is similar in purpose to the above-mentioned ESP32-S Dev Prototype shield, but I have also added some additional cosmetic changes to make it a little easier to use as well.
With many of my prototype designs, I tend to sometimes leave out something, as I usually use it for my own purposes only, but with this design, as many people specifically asked for it, I took a bit more care, as it is no longer just a prototype, right?
What has changed?
The most obvious is the increased prototyping area. The initial ESP32-S version had a 60-hole breadboard-style prototyping area. The new design has 128 prototype holes.
There is also a dedicated power input header, something that I somehow left out on the ESP32-S version... The Flash and Reset push-buttons were also moved inline, and to the bottom of the shield, making it more comfortable to use.
The design retains the plated through-hole design on the prototype area with connecting tracks on both sides of the PCB to allow for a bit more current.
The big ground plane on both sides of the PCB has also been retained.

The prototype shield is for all purposes a breadboard. I did thus not bother with a formal schematic. I believe that it is easy enough to understand the connections by just looking at the two images above.
