 To design our board we used AUTODESK EAGLE application. We designed schematics and PCB for our board in EAGLE. This board will be interfaced with SJOne board's GPIO, power and GND pin. For the schematic design, we used SparkFun library components like switches, LEDs, connector, resistors. After done with schematics, EAGLE generates board design based on schematics we create. Inboard design it's on you how you minimize the board space place your components in the board. After done with the proper design we can either opt for auto-routing or manual routing thing to route the various components in the board. While routing, use proper values of width and drill size for the route. After done with routing check for any errors in the board connections using ERC and DRC tools. We designed dual layer pcb just for the sake of testing. for the common ground, we used ground polygon that makes circuit design simpler. While routing note down the drill size and width of traces it must be sufficient enough to for current flow in the wire.

 === User Input Output Module (UIO) ===
 The indicators on the bike serve to be of great help when changing lanes and taking turns. This avoids the cyclist to extend his hand to indicate turns, thus making it more convenient to ride in high traffic areas where lane changing must be done with utmost care. Two buttons and LEDs are used to indicate in this module to implement the function of indicators. The buttons trigger for the action of the indicators to be displayed on the helmet and LED on the indicator panel helps the cyclist to recognize the state of the indicators.<br>

 ==== Hardware Interface ====
-The UIO Module is interface on board one (transmitter) side. It has two leds, two switches which is connected to SJONE GPIO pins. The UIO board is attached near to the Board one at cycle handle so that it will be easy for cyclist to pressed the UIO switch when taking turn or changing lane.
+The UIO Module has two leds, two switches which is connected to 4x1 pin connector internally. So if you want to connect the switches and leds to any external board just connect the respective connector pins to the external board.

 === Message Handler Interface (MHI) ===
 The Message Handler Interface is responsible for sending out an event packet over WIC-TX, but still need to prioritise the events as described above.
-==== Implementation ====
+==== Design & Implementation ====
 gHalo_MHI_BroadCast() API provided is used by USS, MAE and UIO to broadcast their events which get asynchronously handled in the MHI.
-MHI on the other hand uses a  QueueSet implementation which blocks on the availability of event(s) from any of the user blocks (namely USS, MAE and UIO).
+MHI uses a  QueueSet implementation which blocks on the availability of event(s) from any of the user blocks (namely USS, MAE and UIO).
 As soon as an event is available, the xQueueSelectFromSet() API unblocks providing MHI the opportunity to prioritise event message dequeue. The prioritisation mechanism follow a simple rule assuming the queue at the lower index of the Queue array is the highest priority. So, the implementation do a simple loop starting with the highest priority queue (USS) check and dequeue through to the lowest priority dequeue (UIO).
