What we also know from the libraries and code in the released IoT examples:

• The SoC is built around the Tensilica Xtensa LX3 processor (see the compiler info in the library binaries)
• The CPU is clocked at 80 MHz (esp_iot_sdk_v0.6/include/eagle_soc.h, line 58)

There are readily available compilers for the Xtensa platform (linux-xtensa-gcc via kernel.org), but disassembling binaries may be tricky due to Tensilica Instrunction Extensions (but an linux-xtensa-objdump is freely available via kernel.org).

on this site some infos about GPIOs is available:

there is even a devboard shown!

The module at details.1688.com is a different module. The price is about the same though.

Their module exposes a lot more pins and appears to have some cool features implemented in their firmware.

I would really like to find a distributor for that module too.

Nice find guys!
