====== GutterNode ======

This is a node to fit in James' 3D printed gutter enclosure. An Atmel ATMEGA328P means it is Arduino compatible.

It has a [[jon:cn3083|CN3083]] solar/LiPo charger on board. It also has a footprint for a HTU21D temperature/humidity sensor.

There are connections broken out for a DHT22 temperature/humidity sensor, and serial TX/RX.

Test pads:
  - Test pad 1 is "OK" - pulled high at charge termination
  - Test pad 2 is "CH" - pulled high during charging

Error states are other combinations of the TP outputs, you should check the datasheet for details.

Parts list:
  * U3 MCP1700 SOT-23 3.3V regulator
  * U4 CN3083 charger
  * C1, C2 1uF
  * R3, R4, R5, R6, R7, R8 100k
  * C7 22uF
  * R2 3.6k
  * C6 4.7uF
