README.mdPen Plotter Controller Board
Eine selbst entworfene PCB-Steuerplatine für einen DIY Pen Plotter, entwickelt in KiCad. Die Platine steuert zwei Schrittmotoren für die XY-Bewegung, einen Servo für den Stifthub und übernimmt Benutzerführung sowie Energiemanagement vollständig auf einer einzigen Platine.
Funktionen
- ESP32 – Haupt-Mikrocontroller (Breakout aufgelötet) für Bewegungssteuerung und Logik
- 2× TMC2209 – Schrittmotortreiber (Breakouts aufgelötet) mit UART-Konfiguration, stealthChop und stallGuard
- SG90 Servo – Stift-Auf/Ab-Mechanismus
- I2C LCD-Display – Angeschlossen über Steckverbinder
- Drehgeber – Manuelle Steuerung und Menünavigation über Steckverbinder
- Buzzer – Akustisches Feedback
- 5V Buck Converter – (Breakout aufgelötet) Erzeugt die interne 5V-Versorgungsschiene aus 24V
- 24V DC-Eingang – Versorgung über externen Transformator (DC-Hohlbuchse)

Questions
How big is the Pen plotterV2 PCB?
It measures 122.5 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pen plotterV2 use?
28 parts, built around the SS8050. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Pen plotterV2 KiCad files?
From the tomatencode/PenPlotterV2PCB repository on GitHub, at the commit this page was made from: the board is pen_plotterV2.kicad_pcb and its schematic pen_plotterV2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pen plotterV2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask tomatencode before reusing the design.
