Flux helps you build PCBs faster with an AI teammate!
Create your account to collaborate, stay updated, fork your own version, and get instant answers from our AI agent.

AI-Powered Component Placement
Let AI place your components intelligently. AI Placement analyzes your schematic and positions components for optimal routing, signal integrity, and board density.
From Schematic to Layout in Seconds
Skip the tedious manual placement. AI Placement generates a starting layout you can refine, saving hours of repetitive work on every new design.
Works With Auto-Layout
Pair AI Placement with Auto-Layout for a complete AI-driven PCB design flow — from component placement through trace routing, all with one click.

- Pins 1, 2, 4, 5, 9, 10, 12, 13: These are input pins (1A, 1B, 2A, 2B, 3A, 3B, 4A, 4B) and typically could require pull-up or pull-down resistors to avoid floating states.
- Pins 3, 6, 8, 11: These are output pins (1Y, 2Y, 3Y, 4Y) and generally do not need pull resistors.
- Pins 7, 14: These are power (GND, VCC) pins and shouldn't need pull resistors.
IRA-S230ST01 Passive Infrared Sensors (PIR1 and PIR2):- Pins 1, 2, 3: DRAIN, SOURCE, GND. Typically, these do not require pull resistors.
SN74LS02NSR Quad 2-Input NOR Gate (U3):- Pins 2, 3, 5, 6, 8, 9, 11, 12: These are input pins (1A, 1B, 2A, 2B, 3A, 3B, 4A, 4B) and typically could require pull-up or pull-down resistors to avoid floating states.
- Pins 1, 4, 10, 13: These are output pins (1Y, 2Y, 3Y, 4Y) and generally do not need pull resistors.
- Pins 7, 14: These are power (GND, VCC) pins and shouldn't need pull resistors.
DM7404M Hex Inverter (U2):- Pins 1, 3, 5, 9, 11, 13: These are input pins (A1, A2, A3, A4, A5, A6) and typically could require pull-up or pull-down resistors to avoid floating states.
- Pins 2, 4, 6, 8, 10, 12: These are output pins (Y1, Y2, Y3, Y4, Y5, Y6) and generally do not need pull resistors.
- Pins 7, 14: These are power (GND, VCC) pins and shouldn't need pull resistors.
