Suitable for use in combination with the 
STEVAL-PCC009V2

The EVAL6470PD demonstration board is a fully 
integrated microstepping motor driver. In 
combination with the STEVAL-PCC009V2 
communication board and dSPIN evaluation 
software, the board allows the engineer to 
investigate all the features of the L6470 device. In 
particular, the board can be used to check the 
voltage mode driving and to regulate the L6470 
parameters in order to fit the application 
requirements. The 4-layer layout and the 
PowerSO package allow the top thermal 
performance to be obtained. The EVAL6470PD 
supports the daisy-chain configuration making it 
suitable for the evaluation of the L6470 in multi-
motor applications.
