# Data Acq ## Description This is used on machinery to collect data points. The opto isolator board is 24 vdc to 3.3vdc. when 24 volts applied to board, it will be a zero on the RPI GPIO so you must 'not' every test. We order the opto board from Amazon.com along with the RPI. ## Project Details - **Owner:** aerospaced - **Created:** 9/30/2021 - **Last Updated:** 4/8/2023 - **Visibility:** Public - **Stars:** 1 - **Copies:** 1 ## Key Components ### OPTO 1 — [DST-1R4P-N](https://www.flux.ai/aerospaced/dst-1r4p-n~zh.md) **Pins:** - 1- - 1+ - 2- - 2+ - 3- - 3+ - 4- - 4+ - GND - O1 - O2 - O3 - O4 - VCC ### RPI — [Raspberry Pi 4B](https://www.flux.ai/lwcassid/null~s5.md) **Pins:** - 10/100 LAN Port - 3V3 - 3V3 - 5V - 5V - 5V - 5V - 5V IN - DATA - - DATA - - DATA + - DATA + - DSI Display Port - GND - GND - GND - GND - GND - GND - GND - GND - GND - GND - GND - GPIO 0 (ID_SD) - GPIO 1 (ID_SC) - GPIO 10 (MOSI) - GPIO 12 (PWM0) - GPIO 13 (PWM1) - GPIO 14 (TXD) - GPIO 15 (RXD) - GPIO 16 - GPIO 17 - GPIO 18 (PCM_CLK) - GPIO 19 (PCM_FS) - GPIO 2 (SDA) - GPIO 20 (PCM_DIN) - GPIO 21 (PCM_DOUT) - GPIO 22 - GPIO 23 - GPIO 24 - GPIO 25 - GPIO 26 - GPIO 27 - GPIO 3 (SCL) - GPIO 4 (GPCLK0) - GPIO 5 - GPIO 6 - GPIO 7 (CE1) - GPIO 8 (CE0) - GPIO 9 (MISO) - GPIO11 (SCLK) - HDMI - Micro USB *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/aerospaced/data-acq~38](https://www.flux.ai/aerospaced/data-acq~38).* --- *Generated from [https://www.flux.ai/aerospaced/data-acq~38](https://www.flux.ai/aerospaced/data-acq~38)*
