Data Sheet

MCU
uStepper S-lite uses the successor of the well tested and widely used ATmega328P - the AT-
mega328PB. Why? Because it does the job and does it good! The new upgraded ATmega328PB
has been upgraded on multiple points including double USART, double I2C, double SPI and up-
graded timers !
Stepper driver chip
The TMC2208 features a whopping 1/256th microstepping interpolation algorithm, which means
that it takes in 1/16th microstepping pulses, as send out by most 3D printer controllers for exam-
ple, and dividing each of these into 16 substeps ! This means that the rotor inside the motor travels
much shorter distances between the steps, and hereby significantly reduces the resonances genera-
ted by stepper motors. This in turn ensures that you gets the smoothest possible operation while
keeping the noise to an absolute minimum !
Encoder
The uStepper S-lite uses the AS5600 encoder from AMS, delivering 12 bits resolution and deli-
vers great performance for the money.
Software Features
uStepper S-lite uses the code base of the original uStepper. This will give you a lot of func-
tionality, and some of the key ones are:
• Closed loop position control
• Drop-in capability
• Simple move/stop commands
• Stall detection feedback
• Encoder diagnostics
• Multi-turn absolute position feedback (almost infinite revolutions)
