ESP32 Arrival

And here it is – the ESP32 – or rather the ESP-32 development kit. Mine is in a batch that is running late so my pal has given me his to play with.

ESP32

I figured I’d take a pic in my hand so you can gauge size. This tiny box is what you get – and inside it – precious little! As you ESP32will see below, you get the ESP32 board itself and an adaptor – complete with pins – so you can do some prototyping – so the first thing you’re going to need here is a fine soldering iron bit and some fine solder as the two boards solder together with some pretty close connectors – you should be able to better see these boards by clicking on the image for a larger version.

And that is what comes in the box – no instructions, nothing – next step is to find out what to actually do with this stuff – can’t wait to get my first flashing light running – I can see another learning curve coming on. A link or something would have been nice…

  2. Mains on Asian relays on a $10 board would be a very bad idea. All the Asian relays I’ve seen on the wonderfully low cost modules have relays that place the common or centre contact on the same physical side as the coil contacts. Creepage distances are belorw regulatory requirements and ssfety is a major concern.

    1. Safety I care about.. standards I could give two hoots. Worth checking contact positioning though. Seen some pretty dire Asian supplies. There again virtually every electronic light I have ever seen ignored spacing many having nothing more than a piece of sellitape between mains and case.

      1. I was going to say I have several Chinese boards where the clearances are just fine. I also have some Chinese Power supplies with adequate clearance – and some that are downright dangerous – problem is the resellers don’t have the foggiest idea and will sell anything with a markup.

    1. No that’s fine Bill and thanks for bringing that to our attention. My comments on that board…
      (a) That’s not a bad price and anyone considering buying an Arduino would be daft to ignore it.

      (b) I don’t see the point of emulating an Arduino any more…I rarely use their shields and I don’t see the point in paying for the usb interface when I can use an FTDI to program them.

      (c) What I’d REALLY like to see is a board just like that with a couple of relays on it and mains connectors for the relays – in a box for$10 or British equivalent (dream on)

  4. I woulld not get too tied up with sizes Daniel – as we know, once the chips are actually available, there will be a plethora of manufacturers chucking out boards. Very few of the existing ESP modules were made by Espressif.

    I’m looking into the docs right now – don’t seem to have an SDK manual – and I’m sad to say once again this is all Linux so for some of us there will be a wait until some kind soul wraps this all up in Eclipse for Windows.

    1. hi pete,
      you can use the esp8266 vm under windows and expand.
      http://esp32.com/viewtopic.php?f=2&t=26#p186

      so you can develop with your favority windows ide and jump to the vm to call make.
      between the vm and windows there is a share folder.
      in this you put your develop work directory.
      in vm you say by path setup where the project files are, there can be setup in each projekt by add an “export” command in the makefile.

      if you have soldering the esp318 to the develop board and run your first “boot” let us know, what you see in terminal 😉

      if you scroll down, you see the expanded ESP8266 VM with ESP32 support, this runs under windows.

      just in time, i must make pause. think there is no officially esp318 esptool_”ESP32″.py just in time in the tools sub folder (ESP32 RTOS SDK 1.0 ) , do you know more? 🙂
      must wait for answere from espressif.

      best wishes
      rudi 😉

  6. Could you make a comparison of ESP32 and ESP8266, size, specs etc. Especially which one to use for what 😀
