The Parts<\/h2>\n\n\n\n
Take a moment to unpack your kit and inspect the contents. Your kit should contain the following parts:<\/p>\n\n\n\n

- 1 x DNIN8.100 PC Board<\/li>\n\n\n\n
- 3 x 3 port terminal block, 3.5mm pitch<\/li>\n\n\n\n
- 2 x 3 port terminal blocks, 2.54mm pitch<\/li>\n\n\n\n
- 1 x 2 port terminal blocks, 5.08mm pitch<\/li>\n\n\n\n
- 1 x CD4021BE IC, 16-DIP<\/li>\n\n\n\n
- 1 x 1N5817 Diode<\/li>\n\n\n\n
- 8 x Resistors, 10k\u2126, <\/li>\n\n\n\n
- 1x Resistors, 2k\u2126<\/li>\n\n\n\n
- 1 x LED, Green<\/li>\n<\/ul>\n\n\n\n

<\/a>DNIN8K Digital Input duinoNode Kit<\/figcaption><\/figure>\n\n\n\n You may substitute pin headers of the same pitch (pin spacing) for terminal blocks. The current draw of the board is low enough that it can be powered from the +5v terminal on the LCOS Node (or any Arduino board). Otherwise it requires a 5 volt power source and the ground must be tied to both the power supply ground the microcontroller ground<\/strong>.<\/p>\n\n\n\n
General Instructions & Precautions<\/h2>\n\n\n\n
- \n
- The ICs are static sensitive devices. Work in a low static environment if possible. Make sure to ground yourself while handling the ICs and the board.<\/li>\n\n\n\n
- The ICs and the LEDs are polarized devices. Before soldering, make sure you have the leads in the correct holes. Pin 1 of the ICs goes in the square pad; the anode of each LED also goes into a square pad. Resistors are not polarized and may be placed in any orientation.<\/li>\n\n\n\n

<\/li>\n\n\n\n- The ICs have a small half-circle indentation on one end of the chip; this marks the end with pin 1. At the IC locations on the board, the rectangular locating outline has a break where the Pin 1 indention should go.<\/li>\n\n\n\n
- Work with adequate light and ventilation. Avoid breathing fumes produced by the soldering process. Use adequate protective eye-wear and burn resistant clothing. Use a soldering pad to protect your table\/desk.<\/li>\n\n\n\n
- Use a secure holding device to hold the PC Board while you insert and solder parts. Use self-closing (cross lock) tweezers to hold parts while soldering.<\/li>\n\n\n\n
- Low temperature soldering works best with a “wet” tip. Clean the hot tip with a wet sponge and metal cleaning mesh. Put a little solder on the tip of the iron (just enough to make it “wet” — wipe off any excess), touch the wet part of the iron to the part, then apply enough solder to cover the pad, fill the hole and create a gentle slopped joint. Keeping the tip wet, move from pad to pad applying solder as you go. The iron should touch the part no more than 3 – 5 seconds. If something goes wrong, remove the iron and let the parts cool for a minute before trying again.<\/li>\n\n\n\n
- Sometimes with very thin rosin core solder wire there are tiny sections where rosin is missing or inadequate. You’ll know you’ve hit that when the solder melts but refuses to flow onto the board and tends to ball up. You’ll need to remove the failed solder from the board & part, then try clipping a few millimeters off the solder wire; usually that will get past that bad core and restore normal soldering.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
