ESP32 board with almost BluePill factor

Post by RogerClark » Fri Jan 05, 2018 8:41 pm

I noticed this ESP32 board the other day

I don’t think the pinout is quite the same as the BluePill, it looks like it may be the same pin spaceing etc

Hi Roger,

I've noticed those a while ago, but feel they are a bit pricy ...
Prices of ESP32 went down a lot in past few months, for around the same price of those Widora, you can get an ESP32 with OLED along with LoRa such as those :

I've received a set of two recently, but didn't get chance to try them out, still "time is the missing ingredient" ...

Hi Martin

I totally agree, they are now completely overpriced.

Re: EPS32 Lora

I got 2 of them for Christmas, but for me time, is also the missing ingredient.

Coincidently, I've sold my previous house in November, and I'm currently spending most of my time building a new one ... :ugeek:

I have been using this board and hitting my head against a wall. I did go through 3 versions hoping that the new versions would solve the problems. Now I have given up. Instead, I am waiting for that Espressif will release a narrow version quite soon.

Just as a matter of interest, what are the problems with this board and do you know how pin compatible it is with the Blue Pill?

I have 2 of the ESP32 dev boards from Adafruit
https://www.adafruit.com/product/3269

They work as advertised. Back when I purchased, they were on a special for $10.

I have 2 of the LoRa ESP32 boards with OLED. I have used the ArduinoIDE to program several sketches just checking the ESP32, but I have not energized and tested to radio. The WiFi and ESP32 and PC USB all work well.

There is also another board with slim factor, the ESPio32. It is not very common but you can find it on ebay for about 12$, still more expensive than other boards (like DoIT for example). I bought it some months ago and is OK, but it has some problems with autoreset function, most of time does not work and manual reset by button is required. Anyway there is also the "Wemos" Pro ESP32 (not really a Wemos product) board, for about 10$.

Roger,

This ESP32 has totally different pins than any F103 board. My problems have been with WiFi connections. I have over 10 different ESP32 boards and most of them are totally OK. I am pleased with the Adafruit board apparent quality, but I don't like its size.

For ESP32 WiFi, there seem to be new 3 dimensional antennas which could be better than the copper lines on PCB. I don't yet have any experience with those.
