Stepper motors
Stepper motors are an advanced device that, when used with MobiFlight, can display a range of numerical values with high position accuracy. They are often used to create custom analog gauges, such as airspeed and altitude indicators.
Popular options
There is a wide range of stepper motors and driver boards available, most of which work with MobiFlight. A 28BYJ-48 small stepper motor with a ULN2003 driver is a popular option to get started experimenting with stepper motors in a cockpit build.
Other options
x27 stepper motors are also common. They are compact, and can be connected directly to a board without the need for a separate driver. When paired with a AX1201728SG driver chip, they are capable of fast and smooth movements.
BKA30D-R5 dual-shaft stepper motors are convenient for analog gauges with two needles, such the altitude gauge. They can be connected directly to a board without the need for a separate driver. When paired with a AX1201728SG driver chip, they are capable of fast and smooth movements.
The TB6600 driver is a common option for driving larger Nema 17 stepper motors, like those found in 3D printers and small CNC machines.
