X-NUCLEO-IHM05A1

X-NUCLEO-IHM05A1 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 For further information contact your local STMicroelectronics sales office 1/4 www.st.com 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 GND GND - 1 2 3 4 5 6 CN8 CON-1x6 1x6 - pitch 2.54 DocID028114 Rev 1 10 9 8 7 6 5 4 3 2 1 VREFA GND VREFB RESET POWERSPIN 8 CW/CCW 7 CLOCK 6 CONTROL 5 HALF/FULL 4 VREFA 3 EN 2 1 CN9 CON-1x8 1x8 - pitch 2.54 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 CON-2x19 CN10 CN5 CON-1x10 1x10 - pitch 2.54 Nucleo F0:R15=0 R8 2.2K RCB SENSE-A 12 YELLOW D3 YELLOW D4 C10 820PF 47K 47K 10K 0R3 0R3 R12 R1 R2 SENSE-B OUT-B- 32 25 OUT-B+ 22 10K R13 10K R14 YELLOW D2 100UF 63V + C12 YELLOW D5 100UF 63V + C1 C12 Radial instead of C1 SMD 10K R10 SENSEB OUT-A- 5 100NF 100NF OUT-A+ C2 C3 15 VS R11 R9 RCB VREFB 36 19 18 1 37 68NF 24 26 SENSEA OUT2B OUT1B OUT2A OUT1A 35 34 31 23 21 20 17 16 14 6 3 2 C8 C11 820PF VREFB RCA GND GND GND GND EPAD VREF A Select : 4.7K 68NF 13 L6208PD U1 1 NC#35 NC#34 NC#31 NC#23 NC#21 NC#20 NC#17 NC#16 NC#14 NC#6 NC#3 NC#2 0R R15 2.2K RCA VREFA CW/CCW CLOCK HALF/FULL CONTROL EN RESET VBOOT R6 C7 11 C W /CCW R7 10 CLOCK 9 27 HALF/FULL VREFA 28 CONTROL 8 29 ENABLE VCP 4.7K R5 C9 30 100NF 100R R3 10NF C5 BAR43 220NF VSA P W M-B P W M-A 1 2 3 4 5 6 7 8 7 C6 5.6NF RESET VBOOT 100K 2 C4 D1 VCP R4 CON-2x19 CN7 4 - - 1x8 - pitch 2.54 CN6 CON-1x8 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 - 2/4 3 VSB - 33 - Vin 3.81 MKDS1/6-3.81 6 GND B+ 5 B4 A3 A+ 2 CN1 1 1 - Schematic diagram X-NUCLEO-IHM05A1 Schematic diagram Figure 1: X-NUCLEO-IHM05A1 circuit schematic 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 GSPG1007151530SG X-NUCLEO-IHM05A1 2 Revision history Revision history Table 1: Document revision history Date Version Changes 17-Jul-2015 1 Initial release.
