These devices have been consolidated to eliminate redundancy as they essentially convey the same information. The Ubox, a cost-effective controller from Spintend, boasts a modest current capacity of 100A, an improvement over FM controllers. The Ubox 80 and Ubox 100 have maximum voltages of 75.6 and 84, respectively, making them suitable for current popular battery options. While they support LED connectivity with a 12V 2A connector for lights, it's worth noting that this feature is susceptible to burnout and challenging to repair. The Ubox 80 offers decent Bluetooth connectivity, although the connection may be lost if you move away from the board, whereas the Ubox 100 provides a slightly improved Bluetooth range. Users can opt for either a momentary or latching power switch based on personal preference. Although the included heatsink is sufficient, it is advisable to mount it on at least an aluminum lid to prevent overheating. Notably, these models lack an internal pulldown resistor for the footpads, necessitating alternative solutions.
