* Install the Power LED, D7. The LEDs are polarized and must be installed with the proper orientation. The long lead is the anode and must be placed in the round solder pad that is marked with an "A". The flat side of the LED (the short lead side) goes in the square pad marked with a "K". This is exactly opposite of the Channel LEDs in the next step! Bend back the leads slightly as done with the resistors. Solder one lead and check from proper alignment. Then, solder the other lead and trim off the excess. | * Install the Power LED, D7. The LEDs are polarized and must be installed with the proper orientation.

* Install one (1) 2-pin vertical header JP1. These headers are not polarized so the orientation is not important. Once again, a small piece of tape works well to hold the header in place. Solder one lead, check for alignment, then solder the opposite lead. No trimming is required for this component. | * Install one (1) 2-pin vertical header JP1.

* Install the clock oscillator U3. The oscillator must be installed in the correct orientation. The oscillator has three rounded corners and one squared corner. Make sure that the squared corner is positioned to match the PCB silkscreen. Solder Pin #1, and then verify that the component placement matches the silkscreen and that the component has not "slipped" out of the hole. Once verified, solder the the remaining pins. Trim the excess leads as you would with a resistor or diode. | * Install the clock oscillator U3. The oscillator must be installed in the correct orientation.

* Install the 47uF capacitor C2. This capacitor is polarized and must be installed correctly. The capacitor should have a silver/grey stripe on the body to indicate which lead is negative. The positive lead of the capacitor will be the longer lead. Make sure that the positive lead is placed in the square solder pad. Then, bend the leads back slightly to hold the capacitor in place. Solder and trim the leads the same as the other passives. | * Install the 47uF capacitor C2. This capacitor is polarized and must be installed correctly.

* OPTIONAL: Install the DE9 connector J22. This connector is only needed if you plan on using a normal serial cable to connect to the first board in the chain. You can, however, make a DE9 x RJ45 cable instead. For boards after the first one on the PC COMM port, this connector is not needed. | * OPTIONAL: Install the DE9 connector J22.

* Install two (2) RJ45 modular jacks J3 and J4. Due to minor variations in manufacturing, some RJ45 jacks are a tighter fit than others. Care should be taken to ensure that the pins are aligned first before applying too much pressure to seat the locking lugs through the board. | * Install two (2) RJ45 modular jacks J3 and J4.

* Install the voltage regulator U1. The voltage regulator must be installed correctly. The voltage regulator's tab/heat sink must be aligned with wider line of the PCB silkscreen outline (facing outwards to the PCB edge). Insert the component and then flip the board over. Solder one pin...then flip the board back over and check for alignment. Simply reheat the joint and position the regulator so that is is square to the board. Solder the other two leads and trim off the excess. | * Install the voltage regulator U1. The voltage regulator must be installed correctly.

Board Assembly
- Note: Pictures will be added as soon as they are available
- The following sequence of steps is by no means the only way to Assembly the Renard 64. It is simply a suggested order of assembly. Many builders have varied opinions on what the order should be. In general, you start with the "shortest" items and work towards the tallest. This generally means that resistors are first and connectors are last but every board is different.
- A good temperature controlled soldering iron should be used for building the Renard 64. Try to get the smallest diameter rosin core solder you can find (either 60/40 or 63/37). DO NOT USE LEAD FREE SOLDER!! This takes special equipment and a very high skill set that few DIYers have. If you do use Lead Free Solder and have problems (which is VERY likely) please let us know when you ask for help. Lead Free Solder can look like a good joint but still not be electrically conductive.
- One safety note is prudent here. Solder is METAL (lead and tin)...In order to use it,it must be MELTED. HOT, Molten Metal can BURN! Also, metal leads get hot while soldering. So, any unprotected fingers that are being used to "hold" a component in place will be burned!! Painter's tape is one way of holding items down while the board is being flipped over. Another way is to use another unpopulated board or flat surface to allow the board to be flipped while keeping the components in place.
- NOTE: The part numbers referenced in the following instructions are those taken from the Renard 64 BOM.
