Branca Board

Branca Board is composed of the STMicroelectronics’ Wi-Fi module SPWF01SX.11,a USB interface to enable interaction with the module, a JTAG connector to program/emulate, and a temperature sensor to work as simple sensor node application.

All the pins of the module are available through a simple through-hole connector. Schematics and gerber files are available online freely after registration.
