ESP32 with small PCB searched.

Postby ROB_87 » Mon Jul 31, 2017 4:45 pm

Hi,

I'm Robert from germany. I searching a ready to use small PCB with a ESP32 on it. Do you have a advice where I can find such?
It ist for a RC-Car(1:24) project.

It isn't necessary to have all pins outside, because I would like to use a bus system.

https://de.aliexpress.com/store/product ... 53522.html This looks good but it has a USB-Chip on it, witch I don't need i think.

Thank's for your help.


Robert

Hello Robert. Have you already looked at the modules that do not have a DIP pinout? For example, the module you mentioned is based on the WROOM32 module, which is also obtainable separately.

Thats the smallest that I own:

The photos don't really do it justice, its amazingly small while still full-featured. Not cheap though. Remember you'll have to set the flash to DOUT mode.

nice - you know, that the modul can't connect to a breadboard?
( double pinheader pins left and right are nice but they are different signals from neighboring pin)

best wishes

Yep, they look nice at first sight but I never use them because of this.

You can solder two outer rows of pins on bottom side of board and two inner rows on top ;)

Yes, I know. I will use a PCB solution. I want to explore low power consumption ESP32 designs using batteries, deep sleep and BLE.

ah :idea: one row it wants to be put on the breadboard and the other row put from above
very nice :D this modul becomes own special character.
then perhabs better, we connect wire from the board to the breadboard ?
Or we will take an adapter hole grid board for soldering the breakout adapter board
and then we wire the hole grid board to the breadboard -
i see - this is a good exercise for beginners :mrgreen:
(After the exercise then:: we make then an adapter board for the hole grid board that fits on a breadboard too)
