## What it is
BIGTREETECH SKR V1.3 is a 32-bit 3D printer control board based on the LPC1768 MCU, with hardware design files and firmware support for Marlin 2.0 and Smoothieware. It features onboard TMC2130 SPI and TMC2208 UART interfaces for stepper drivers and supports LCD2004/12864 displays.

## Use cases
- upgrade a 3D printer to a 32-bit control board
- run Marlin 2.0 on an LPC1768 printer board
- use TMC2208 UART or TMC2130 SPI stepper drivers without extra wiring
- build or repair a DIY 3D printer mainboard
- connect a 2004 or 12864 LCD to a printer controller

## When to choose
- you need an open, well-documented 32-bit mainboard for a Marlin or Smoothieware printer
- you want plug-free TMC2130/TMC2208 driver support
- you are building or retrofitting a 3D printer with a 32-bit board

## When to avoid
- you need a newer board with more features (e.g., SKR V1.4 or 32-bit boards with WiFi)
- your printer requires a different MCU architecture or firmware ecosystem
- you need active ongoing development - the last release was January 2021
