LoRa Node Kit

• Make sure to switch your FTDI programmer to 3.3V
• Solder the two pins on the inner side of the Arduibno (A4,A5) as well, they are for I2C

• HowTo: [TTN Lab]
• Code: [GitHub]

LoRaWAN Application

• This is not complete or secure at all. Drop me a line if you want to get an update on this when I figure this out. But please don't run this on a public server just like that
