Edit October 2015 : New Revision 1.0a with better SMA connector for RF module

The gateway can host several funny things like

• Socket to plug a Spark Core or Particle Photon
• Pins to connect I2C or SPI OLED 128x64
• Pins to connect 2.2" or 1.8" TFT LCD
• RFM69 or RFM12B on board module
• Lipo Battery connector for testing and move the Gateway (no charger on board)
• 3V3 On board regulator for harvesting devices if any to avoid pumping from Particle Regulator
• Data connection for any cheap ebay ASK RX receiver
• FTDI connection for those who want to debug serial or send data over real serial
• 2 x grove I2C connector to connect other I2C devices

Everything is documented on this dedicated post

Reference from Seeedstudio Open Part Libray SKU but can be ordered on any provider, Digikey, Mouser. Link to the BOM file.

For SPARK connector I use IC socket that I cut on needed size, for other connectors, I usually buy 40 pins headers (male and female) on ebay that I cut at the needed size. Example

You can order the PCB of this board at OSHPARK
