___
Turn the board over, and solder the two leads to the pads. With a set of small diagonal
cutters, clip off any extra leads.
___
Turn the board back over, and remove the tape. Also remove the protective cover on
the buzzer.
Mount the Headers
___
Locate the spot for the three 3-pin headers near the bottom-center of the PC board.
___
Put the headers in place, so that the short end goes through the PC board. With some
masking tape, hold them in place. Turn over the board, and solder the pins to the pads on the
PC board. Turn the board over again, and remove the tape.
Mount the Terminal Block (optional)
Optionally, you can install the 4-pin terminal block for your deployment wiring. Given the
relatively low cost of a Quark, we generally recommend that you hardwire it to your sled by
soldering your deployment wiring to the board, and don't remove it. However, some people
like the convenience of removable screw terminal blocks for their wiring, so we've designed
the board to take them too.
Hardwired
• Lower Profile possible
• Requires soldering the wires
• Can't come loose in flight
• Not easy to move
• Servo tape mounting OK
Terminal Blocks
• Slightly taller profile
• Wires are simply screwed into the blocks
• Wires can potentially vibrate loose in flight
• Easier to move between rockets
• Requires screw mounting due to torque
