Unfortunately the TMC5130 doesn't support closed loop operation so this is only for failure detection. It has a theoretical 1° resolution and can be used to control the stepper operation and correct position in case of missed steps. This board supports a magnetic absolute encoder IC from AMS : the AS5132. It has a NEMA17 form factor and can be mounted directly on the back of a stepper motor.įarfadet TMC5130 - v1.0 (red) vs v1.1 (green) The magnetic encoder board No need to generate a Step/Dir signal from a microcontroller with a library such as AccelStepper, it will always operate jitter-free and with 256 microsteps.Īdditionally, this chip can run in a silent mode called stealthChop and integrates advanced features from Trinamic like stall detection (useful for sensorless homing). This is a very complete chip that integrates a hardware ramp generator : it only needs a power supply (12 - 45V) and a serial data bus to operate. It is based on Trinamic's TMC5130A and can drive a single stepper motor with up to 1.5A / phase. At the moment, the Farfadet collection is composed of the following boards : The main Farfadet board
