X - N U C L E O - I H M 0 5 A 1 Bipolar stepper motor driver expansion board based on the L6208 for STM32 Nucleo Data brief Description The X-NUCLEO-IHM05A1 is a bipolar stepper motor driver expansion board based on the L6208 driver for bipolar stepper motors. It provides an affordable and easy-to-use solution for driving bipolar stepper motors in STM32 Nucleo projects. The X-NUCLEO-IHM05A1 is compatible with the Arduino UNO R3 connector, and supports the addition of other STM32 expansion boards with a single STM32 Nucleo board. The user can also mount the ST Morpho connector. Features Voltage range: 8 V to 50 V Phase current: up to 2.8 A r.m.s. Dual independent PWM current controllers Fast and slow decay mode selection Decoding logic for stepper motors, full and half step drives Overcurrent protection Thermal protection shuntdown Compatible with Arduino UNO R3 connector Compatible with STM32 Nucleo boards RoHS compliant July 2015 DocID028114 Rev 1 1/4 www.st.com For further information contact your local STMicroelectronics sales office Schematic diagram X-NUCLEO-IHM05A1 1 Schematic diagram Figure 1: X-NUCLEO-IHM05A1 circuit schematic NC 35 35 VSB NC 34 33 34 NC 31 31 VSA NC 23 4 23 NC 21 21 NC 20 20 NC 17 17 NC 16 16 NC 14 14 VCP NC 6 3 VCP 7 6 NC 3 3 NC 2 2 GND 36 VBOOT GND VBOOT 30 19 GND 18 GND 1 EPAD 37 1 2 3 4 5 6 1 2 7 8 1 10 3 4 - 9 10 2 9 5 6 - 11 12 3 8 7 8 13 14 - 4 7 GND 9 10 - 15 16 5 6 11 12 - 17 18 6 5 13 14 19 20 GND 7 4 VREFA 15 16 21 22 GND 8 3 17 18 - 23 24 2 VREFB 19 20 25 26 1 RESET POWERSPIN 21 22 27 28 23 24 29 30 25 26 31 32 27 28 33 34 29 30 35 36 31 32 37 38 1 8 CW/CCW 33 34 2 7 CLOCK 35 36 3 6 CONTROL 37 38 4 5 HALF/FULL 5 4 VREFA 6 3 EN 2 CN8 1 CON-1x6 CN9 1x6 - pitch 2.54 CON-1x8 1x8 - pitch 2.54 GSPG1007151530SG 2/4 DocID028114 Rev 1 CN7 C4 220NF CON-2x19 D1 BAR43 2 1 C12 Radial VS instead of C1 SMD C5 10NF C3 C2 + C1 + C12 CN6 100UF 100UF CON-1x8 R3 100NF 100NF 63V 63V 100R 1x8 - pitch 2.54 RESET R4 100K C9 C6 100NF 8 CN1 RESET 5.6NF ENABLE 29 15 OUT-A+ 1 A+ EN OUT1A CONTROL 28 2 A- CONTROL 5 OUT-A- OUT2A HALF/FULL 27 3 B- HALF/FULL CLOCK 10 4 B+ CLOCK 22 OUT-B+ OUT1B CW /CCW 11 5 GND CW/CCW U1 32 OUT-B- 6 Vin OUT2B R5 L6208PD PW M-A VREFA 9 MKDS1/6-3.81 VREFA 3.81 4.7K RCA 13 RCA R7 12 SENSE-A SENSEA C7 2.2K 68NF VREFB 26 25 SENSE-B VREFB SENSEB 24 RCB YELLOW YELLOW YELLOW YELLOW RCB D3 D4 D5 D2 R6 R2 R1 PW M-B 0R3 0R3 4.7K R8 2.2K C8 R11 R12 R13 R14 R15 VREF A Select : 68NF 10K 10K 10K 10K Nucleo F0:R15=0 0R C10 C11 820PF 820PF R10 47K R9 47K CN5 CON-1x10 1x10 - pitch 2.54 CN10 CON-2x19 - - - - - - - - - - - - - -
