I ordered some ESP8266 chips from Aliexpress and am designing a simple Teensy 3.1 add-on with this soft-AP wifi capable chip. I have an NDA with espressif now and am getting good info about the chip from them. I expect to have a tested OSH Park board design with a pcb antenna that should be rather easily assembled with low temperature solder paste and a hot plate, include 128 Mbit SPI flash memory chip and mount either at the non-USB end of the Teensy 3.1 or standalone on a breadboard. I expect to sell them at Tindie for about $20, starting in May. If you can wait a few weeks, you can just order the boards from OSH Park and assemble your own wifi-capable Teensy 3.1!

@onehorse, at $20 you might not sell many I pay £2 for the ESP8266 and my adapter costs about £1
at $20 you might not sell many
working drivers/sample programs
I can program the Teensy as normal, then load a serial 'pass through' program to Teensy, switch to the ESP8266 in the IDE & program the ESP8266.
My adapter IS appallingly small! It's SO small that it's invisible to the naked eye! That's an antenna you see in the photo, not the adapterAlso, your adapter is not appallingly small; that is value subtracted in my view!
That's a very old page NOT a good starting pointThere is a nice website with a lot of info on this chip.
I guess that's down to Paul. I don't see an obvious way to do this & it's not something I really need.Can we go in reverse?
I didn't mean to question your motive.
leave out the Teensy
will make a good 'partner to the Teensy'
