Hello everyone.
I have been working on home-automation for a very long time but I was using atmega328 standalone mcu but now I want to step it up. So for that I want to use ESP32 and ESP12 but I am having a very hard time to get a pcb for those. Is anyone having a pcb design or schematic link to these . It should be a general just for programming and the reset of circuit I will add myself. Basically a development board pcb just like nodeMCU or something
They make the wroom-32 that you can install on your custom PCB
google wrover-32 and wroom-32
There are a multitude of development boards (nodeMCU like) with all manner of pin-outs, so many that there is no standard.
but, if you are looking to buy the individual parts, then you need to look at the Expressif documentation. the chip is not ESP32 or Expressif, it is a Xtensa®32-bitLX6microprocessor.
the ESP-32 is just a board, made up from discrete parts and sold as a package.
the 'assembler' is Expressif.
the parts are made by multiple different manufactures.
Think Arduino and the microcontroller is made by Atmel.
Thanks for reply.

I want the pcb or schematics for this so that i can program it and stuff.
I dont see that the internal schematic of the wroom-32 would be much help, even if they did publish it.
I think what your meaning to ask for is a schematic of a module such as the nodeMCU or similar 'ESP32' module so that you can replicate it.
Not sure if anyone has published a free to use PCB for the wroom-32, most people make their own.

every component is available and has a data sheet.
Expressif took those separate parts and made a module. I do not believe they have made it open source.
but there is no reason you cannot get the data sheets and create your own module or board.
I think you will find that it will be much more expensive than if you were to buy the wroom module and soldered it to your board.
if you are looking to compete, you need to run the costs. you would have to make a million, then get your government to sponsor the costs.
look at the cost of an UNO from China where the costs are covered by the government and the cost from any other supplier.

Schematics and CAD files are available for the original NodeMCU 1.0.
SparkFun and Adafruit also publish schematics and CAD files for the boards they design and sell. You may have a do little digging to find them but they are available. Both sell ESP32 boards as well as ESP8266.
Hi,
You need to get one of these to experiment with.

Thank you all for your responses but my question is that what extra circuitry I need to program the above mentioned esp12 and esp32.
For the ESP-12, look here.

Hi,
For the ESP32, you use the same hardware for Arduino and the IDE.
google esp32 arduino
Also lookup on YouTube...
