## What it is
OpenPnP is open source software (with accompanying hardware designs) for controlling SMT pick and place machines used in PCB assembly. It can run DIY machines or replace OEM software on commercial machines.

## Use cases
- control a DIY SMT pick and place machine
- automate PCB assembly at home
- replace OEM software on a commercial pick and place machine
- run vision-guided component placement
- build an affordable pick and place machine under $1000

## When to choose
- you are building or operating an open source or custom SMT pick and place machine
- you want free, actively developed machine control software for PCB assembly
- you want to retrofit existing commercial machines with better software

## When to avoid
- you need turnkey commercial manufacturing software with vendor support
- your workflow does not involve SMT placement or PCB assembly

## Facets
- artifact type: application
- maturity: active
- function: machine-learning, computer-vision, robotics, gui, developer-tools
- domain: robotics, hardware
- platform: cross-platform, jvm
- tags: pick-and-place, smt, pcb-assembly, electronics-manufacturing, machine-control, open-source-hardware, automation, manufacturing, desktop
