Raspberry Pi 4/3B Relay HATRelays are very important switching components that we use pretty often.Components details:Relays:Mfr. Part #SRD-05VDC-SL-C5VDC SPDT -General Purpose Non Latching Through Hole RelaysROHS Compliant(250VAC) Max Switching VoltageScrew terminals:Manufacturer: METZ CONNECT GmbHMfr. Part #31001102Type: Through HoleNumber of Positions: 2Type: Wiring Board - Line to BoardPitch0.197"(5.00mm)Mosfets:As the GPIO current of Raspberry Pi is quite low, It is a good practice to use MOSFETs for switching through 5V bus. SoManufacturer: MDD（Microdiode Electronics）Mfr. Part # MMBT5551160V 0.3W NPN 0.6A SOT-23-3 Bipolar Transistors - BJT ROHS CompliantGetting Started:Raspberry Pi 4" Your tiny, dual-display, desktop computer…and robot brains, smart home hub, media centre, networked AI core, factory controller, and much more"To Setup Your Raspberry Pi for the First time, Check this link belowSetting up your Raspberry Pi - Introduction | Raspberry Pi Projects https://projects.raspberrypi.org/ GPIO pins allow adding extensions to your Raspberry Pi, whether with HATs or to create circuits. The easiest way to use them is to create Python scripts, but Scratch or other software are good options to consider.To Configure GPIO:Step 1. Download and install OAS onto Raspberry Pi 4 device. View the Raspberry Pi Installation guide for an easy to...Step 2. Setup access to gpiomem for the user account the OASEngine is running under. The default is oasuser.Step 3. From a Windows system start Configure OAS application from the program group Open Automation Software.(Helpful Links: Getting Started Raspberry Pi GPIO | Industrial Internet of Things Data Platform | (openautomationsoftware.com) )For PINOUT description:https://raspberrytips.com/wp-content/uploads/2019/04/raspberry-pi-pinout.png?ezimgfmt=ng:webp/ngcb45Dimensions & PCB Info:Size:64.99mm x 56.01mmSignal Layers:2None Signal Layers:10Length of Tracks:121.5mmCopper Areas:2Open Source Design:This is an Open Source design with all the files and documentation available to General Public Under GNU V3.0 License.
