A

• ADC: A type of electronic circuit component that converts analog signals to digital signals. You will find 2 of these used for your foot sensors, measuring the voltage. A low voltage (usually below 0.5 Volts) means it’s not engaged aka off, whereas a higher voltage (usually above 2.0 Volts but mostly close to the maximum, aka 3.3 Volts)

B

• Balance App (obsolete): In v5.3 and older we used to select the balance app. Since 6.0 we have packages so we no longer select an “app” in App Settings
• Balance Package (obsolete): A package of software settings and controls that controls the balance and stability of a Onewheel.
• Battery: a container consisting of one or more cells, in which chemical energy is converted into electricity and used as a source of power. The batteries we use in the OneWheel world are lithium-ion batteries. Check out our article on battery basics here.
• BMS: a device required to safely operate/charge your Lithium battery. View the article on BMSs here.

C

• CannonCore: Onewheel motor made by Floatwheel, also has the same dimensions as a Hypercore but it has a hollow axle. Much more powerful than the Hypercore (probably similar to SuperFlux) and with a similar K$v$ as the Hypercore. View the article on the CannonCore here.
• Cell/Cells: Referring to the individual battery cells in a battery pack.
• Cutoffs: VESC motor controllers have lots of cutoff options used for safety in e-sk8/e-bike applications, e.g. when the temperature gets too high or voltage gets too low - For Onewheels cutoffs mean nosedives, so we always want to avoid cutoffs and configure tiltbacks instead to alert the user that something isn’t right

D

• Duty Cycle: The duty cycle is a term used in electronics to describe the proportion of time a signal is active or "on" compared to its total operation time. It is often expressed as a percentage and is crucial in applications like pulse-width modulation (PWM). check out the article on Duty Cycle found here.

E

• ERPM: it stands for effective RPM (rotations per minute) which is based on magnets rather than wheel rotations. For our use, 1000 erpm translates to roughly 2 mph or ~3km/h

F

• Float Control: iOS App to enable easy custom shaping for VESC boards.
• Float Package: VESC Package for “one-wheeled skateboards” made by @Nico Aleman See #float-package for more information..
• Footpad: The platform on a Onewheel where the rider places their feet.
• Field Weakening: a technique used to allow brushless motors to run faster - see our article on field weakening here.
