 +====== Cylon_HAB_Dock_Board ======
  
 +{{wiki:​CylonHABDockBoardPopulated.JPG?​300|Completed Dock Board.}}
 +The Cylon HAB Dock Board is the central connecting PCB for the Cylon HAB. It integrates the IOIO, Relay Shield, Altimeter, and Radio. In effect, it is a hard wiring harness.
 +
 +=====Purpose=====
 +{{wiki:​DockBoardConfigured.jpeg?​300|Dock configured with IOIO and Relay Shield.}}
 +The purpose is to provide a dock for the HAB's avionics. This board connects the IOIO to a relay shield, the TinyTNC and an altimeter module. It also allows expansion of the avionics package over a standard Arduino Style Shield connection.

 +=====PCB=====
 +{{wiki:​CylonHABDockBoardUnPopulated.JPG?​300|Bare dock board before populating with components.}}
 +{{wiki:​CylonHABDockBoardV10.png?​300|Top rendering of Dock Board PCB.}}
 +Created in Eagle. Uses custom parts from Atlantis Roads library. Email [[mailto:​noctividus@gmail.com|Rich]] for source files.
 +====Version 1 Bugs====
 +*Mounting holes are too close to the edge of the board.
 +*Solder pads are too small for audio jacks, need to extend to make soldering easier. (Done)
 +*LED/Key Circuit should drain to IOIO, not source current from it. (Done)
 +*Through-Hole Solder Pads are thin. (Done)
 +*Outline for LED orientation and audio jacks. (Done)
 +*Silkscreen on power connector overlaps a thru-hole. (Done)
 +*Get the date right (Done)
 +*Integrate [[Tiny TNC]]
 +*Add battery (Vin) Voltage monitoring
 +
 +====Improvements Version 2====
 +*Removed TNC Circuit and integrated TinyTNC.
 +*Mapped all IOIO Pins IAW IOIO Shield Dock.
 +*Changed Power Connector.
 +*Decreased footprint.
