Bigtreetech SKR Pico

• 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.
• Marlin: https://github.com/thinkyhead/Marlin/tree/bf2_wip_rp2040_skr_pico_PR
• Benötigt bei Entnahme von mehr als 0,9A pro Treiber aktive Kühlung.
