# Omron G5V-1-T90 Relay (6-pin) ## Description This document provides a detailed guide to building a relay circuit that uses a Raspberry Pi to control a buzzer. The relay acts as a switch, allowing the Raspberry Pi to turn the buzzer ON and OFF through GPIO pins. ## Project Details - **Owner:** aparnapanja - **Created:** 1/2/2025 - **Last Updated:** 1/2/2025 - **Visibility:** Public ## Key Components ### K1 — [G5V-1-T90 DC5](https://www.flux.ai/lcsc/g5v-1-t90-dc5~5032.md) - Product Info Url: https://lcsc.com/product-detail/Relays_OMRON_G5V-1-T90-DC5_G5V-1-T90-DC5_C152707.html - Manufacturer Name: OMRON(欧姆龙) - JLCPCB Part Class: Extended Part - Part Type: Power Relays - LCSC Part Number: C152707 - Package or Case Code: RELAY-TH_G5V-1 - Datasheet URL: https://assets.lcsc.com/datasheet/szlcsc/Download-ISO9001-Certification.pdf - Manufacturer Part Number: G5V-1-T90 DC5 **Pins:** - 1 [pin 1] - 10 [pin 10] - 2 [pin 2] - 5 [pin 5] - 6 [pin 6] - 9 [pin 9] ### Q1 — [BC547-B](https://www.flux.ai/lcsc/bc547-b~zpx2.md) - LCSC Part Number: C2844035 - JLCPCB Part Class: Extended Part - Package or Case Code: TO-92-3_L4.8-W3.7-P2.54-R - Manufacturer Part Number: BC547-B - Manufacturer Name: BLUE ROCKET(蓝箭) - Part Type: Bipolar Transistors - BJT **Pins:** - B [pin 2] - C [pin 3] - E [pin 1] *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/aparnapanja/omron-g5v-1-t90-relay-6-pin~3s](https://www.flux.ai/aparnapanja/omron-g5v-1-t90-relay-6-pin~3s).* --- *Generated from [https://www.flux.ai/aparnapanja/omron-g5v-1-t90-relay-6-pin~3s](https://www.flux.ai/aparnapanja/omron-g5v-1-t90-relay-6-pin~3s)*
