RPI GPIO Shield turned Raspberry Pi GPIO into the normally-used Arduino I/O interface. The shield not only maintained most of Arduino UNO I/O interface,but also expanded IIC interface,UART TX/RX interface, and SPI interface, electronic bricks interface. RPI GPIO Shield inherited the Arduino UNO I / O all the features, which can be used to drive LED, sensors, LCD and other electronic modules and components.

The ESP8266 processor from Espressif is an 80 MHz microcontroller with a full WiFi front-end (both as client and access point) and TCP/IP stack with DNS support as well. While this chip has been very popular, its also been very difficult to use. The Adafruit HUZZAH ESP8266 breakout is what we designed to make working with this chip super easy and a lot of fun. We took a certified module with an onboard antenna, and plenty of pins, and soldered it onto our designed breakout PCBs.

The LilyPad Reed Switch is a simple breakout for a reed switch that will make it easy to use in e-textiles circuits in exactly the same manner that you can currently use the LilyPad Button and Switch. In order to make it more durable for wearable use, we’ve used a different style of reed switch, which is insulated.
