Introduction
The L62xx family evaluation environment is a fast, robust, and easy-to-use solution that allows to evaluate all the brush DC
and stepper motor drivers of the L62xx family in combination with a NUCLEO-F401RE control board and the STSPIN Studio
software.
The kit includes:
•
a compact main board (EVL62XX-MAIN) compatible with the Arduino UNO R3 connector
•
one plug-in board (EVL62XX-PLUG) based on the DMOS dual full-bridge driver for motor control of the STMicroelectronics
L62xx family. In particular:
L6205, L6225, L6206, L6226, L6207 and L6227 to drive from one to four DC motors
L6208 and L6228 DMOS to drive one bipolar stepper motor.
The maximum ratings of the plug-in boards are:
•
power stage supply voltage (VS) from 8 V to 50 V
•
motor phase current up to 1.4 A r.m.s. (L6225, L6226, L6227 and L6228)
•
motor phase current up to 2.8 A r.m.s. (L6205, L6206, L6207 and L6208)

    UM2871 Driving mode selection (L6205, L6225, L6206 and L6226) The driving mode selection is done by properly setting J5, J6, J7 and J8 solder jumpers on the top of the boards. By default, all solder jumpers are open (two bidirectional DC motor driving configuration). The table below briefly summarizes the possible configurations: Table 3.
