| | ===== PHYSICAL SETUP ===== |
| | ''The [[adi>en/mems-sensors/mems-accelerometers/adis16228/products/EVAL-ADIS16228/eb.html|ADIS16228/PCBZ]] provides the [[adi>en/mems-sensors/mems-accelerometers/adis16228/products/product.html|ADIS16228]] on a small printed circuit board (PCB) that simplifies the connection to an existing processor system. This PCB includes a silkscreen, for proper placement, and four mounting holes that have threads for M2 × 0.4 mm machine screws. The second set of mounting holes on the interface boards are in the four corners of the PCB and provide clearance for 4-40 machine screws. The third set of mounting holes provides a pattern that matches the ADISUSBZ evaluation system, using M2 × 0.4mm × 4 mm machine screws. These boards are made of IS410 material and are 0.063 inches thick. J1 is a 16-pin connector, in a dual row, 2 mm geometry that enables simple connection to a 1 mm ribbon cable system. For example, use Molex P/N 87568-1663 for the mating connector and 3M P/N 3625/16 for the ribbon cable. For direct connection to the [[adi>ADISUSB|ADISUSB]] evaluation system, use these parts to make a 16-pin cable or remove pins 13, 14, 15 and 16. The LEDs (D1 and D2) are not populated, but the pads are available to install to provide a visual representation of the DIO1 and DIO2 signals. The pads accommodate Chicago Miniature Lighting Part No. CMD28-21VRC/TR8/T1, which works well when R1 and R2 are approximately 400 Ω (0603 pad sizes).The mating connector for the [[adi>en/mems-sensors/mems-accelerometers/adis16228/products/product.html|ADIS16228]], J2, is AVX P/N 04-6288-015-000-846. The picture below provides a close-up view of this connector, which clamps down on the flex cable to press its metal pads onto the metal pads inside the mating connector. The schematic is for the [[adi>en/mems-sensors/mems-accelerometers/adis16228/products/EVAL-ADIS16228/eb.html|ADIS16228/PCBZ]] board.'' |
