• MKS Gen L
• Bigtreetech SKR E3 1.4 Turbo

Dies waren die ersten Boards von Creality mit TMC Treibern, sie wurden als "Silent Board" verkauft. Es gab jedoch auch 1.1.4 die die alten Treiber hatten und so als OEM kamen. Man kann es leider nicht von außen feststellen.

Die TMCs werden im Standalone-Modus gefahren.

• Das Board hat einen RPi Pico Core mit TMC2209 Treibern im Uart Modus.
• Es hat die Abmessungen eines RPi und würde prima mit einem RPi 3, 4 oder Zero 2 zusammen passen.

• Benötigt bei Entnahme von mehr als 0,9A pro Treiber aktive Kühlung.
