DIY Controller Assembly¶
This section is for those who want to build the controller themselves — without a ready-made MCU board.
RP2040 Pinout¶
RJ45 Connector Pinout¶
Three RJ45 connectors (U6/U7/U8) for connecting EXT boards. Each connector carries: SRV (servo), T (temperature sensor), FAN (fan), H (heater), SDA/SCL (I²C), +5 V, GND.
Prototype Board (EasyEDA)¶
Minimal budget, assembled by hand on a breadboard. A functional prototype — not intended for permanent use.
Printer Board + SSR¶
An old printer board as MCU and solid-state relays for controlling 110–230 V loads. Requires available GPIO outputs and compatible Klipper firmware.
