# Mini Carrier Board ## Link zum Premium-Modellbau Shop: {% embed url="" %} Cube Mini Carrier Board - Trägermodul für The Cube (Pixhawk 2.1) im Premium-Modellbau Shop {% endembed %} ## Beschreibung Mini Carrier Board: Das Pixhawk Mini Carrier Board verfügt über den Standard DF17 Stecker und kann mit allen Cubes (Blau, Lila, Schwarz, Orange, Orange+, Gelb) eingesetzt werden. Das Board ist speziell für kompakte Setups vorgesehen bei denen das Standard Board zu groß und schwer wäre. **Es handelt sich um die aktuelle Version mit Abdeckung!** Features: \- Dual Power Input (Bei Ausfall einer Spannungsquelle wird auf die zweite Quelle umgeschaltet) \- Power Distribution (Strombegrenzung um eine Überlastung zu verhindern) \- Voltage Protection (Über - und Unterspannungsschutz) Lieferumfang: \- 1x Mini Carrier Board ## Technische Daten: ## Working Conditions and Performance | About | Description | | -------------------------------------------- | ---------------------------------------------------------------- | | POWER input voltage / rated input current | 4-5.7V / 2.5A; 0-20V is safe for the system but it will not work | | POWER rated output / input power | 14 W | | USB port input voltage / rated input current | 4-5.7V / 250mA | | Servo rail input voltage | 4-10.5V | | Waterproof | Not waterproof.
