About
SPUTNIX SXC-FW4-02 is an autonomous actuators module of four flywheels with drivers and control electronics for 3U or larger nanosatellites. Uses a single PC/104 connector with power and CAN bus. Each flywheel driver has its own CAN ID. Designed for use with SPUTNIX SXC-MB-04-ADC ADCS controller. Supports in-flight firmware update via bootloader.
