Matt, Most of the ESP8266 modules themselves (rather than the development boards) have a rather inconveniently sized, castellated solder-pad arrangement which makes them quite awkward to solder onto perfboard or stripboard. If you're only planning on using the WiFi capability, the ESP8266-ESP01S is a good bet. It's a very small module, but comes with 0.1" pins, so it is a breeze to use with perfboard (although not with stripboard or breadboard). The "S" in the ESP01S is very important, as it indicates that the module has more memory than the old, original ESP01 board (the old boards are blue, but the 01S boards are black and generally have "ESP01S" silkscreened next to the connector).
This eBay vendor ships reasonably quickly and has always sent good working parts to me (so far!):- https://www.ebay.com/itm/ESP-01-ESP-01S-ESP8266-Wireless-Transceiver-Module-Breakout-Breadboard-Adapter/262771926407 Please do note that it is the Chinese New Year holiday right now, so nothing will be moving for another week and a half, at least. Your local Amazon is probably a better bet if you're looking to get one quickly (hint - choose one that is eligible for Amazon Prime, even if you're not a member, otherwise you may end up waiting for shipment from China after all). There are quite a variety of ESP01S + Adapter-Board combinations available for only a dollar or more than the board itself. Two of the most useful adapters are the (red) plug-in USB adapter, which makes it really easy to reprogram the ESP01S module, and there's also a (blue) plug-in adapter which has an on-board 3v3 regulator as well as level shifters and a breadboard-friendly pin-out, so you can plug it straight into an existing (5v) project and be ready to go. For my part, I've been playing with doing the opposite of Rob. I'm trying to offload some of the peripheral work from the ESP8266 onto PIC micros (the ESP8266 is a very powerful microcontroller in its own right, but it does suffer from one drawback ...if you load it down with interrupts, or any tight loop processing for that matter, it will panic and reset, because the single processor needs to have enough free cycles to continuously handle the network). Anyway, I've been fooling around with having the ESP8266 and PIC(s) talk over i2c, but haven't had too much time for any projects recently, so haven't made too much headway. If anyone has any working examples of and ESP i2c master with PIC slaves, I'd love to hear from them. :-) Finally, for anyone who hasn't seen or played with an ESP8266 yet, I have two or three odd modules (mainly older, but working, versions) which I'd be happy to ship out to members of this list in appreciation of all of the support I've received over the years. I'll be shipping from Japan, so don't expect next day delivery :-). One per person. Please reply directly to me, not to the list. Sebastien, you have first option, if you want one (thanks again for the Jaluino Bee). -John- --- On Sunday, 3 February 2019 10:26:08 UTC+9, Matthew Schinkel wrote: > What module did you buy?
