I receive my ESP8266 test board this morning and plan to evaluate the chip.
but I can't find any schematic for the board. I bought it on eBay :
http://www.ebay.fr/itm/ESP8266-Serial-WIFI-Module-test-board-module-coexistence-module-AP-STA-AP-/221575666016?pt=LH_DefaultDomain_0&hash=item3396f05960#ht_1312wt_1399

can anybody point me to the right schematic please.
I would like to know all the switch and push button functions.

thanks, best regards
Phil

I'm also running this board, but I wasn't able to use the built-in chip for updating (also got no docs at all).
Anyone has a clue? You can put the STC15L204EA into some special mode by transferring data at powerup, but I didn't find any host tool to talk to the chip.

Also my dealer didn't know, I asked them about what they knew and they didn't even come up with the schematics.
