X - N U C L E O - I H M 0 4 A 1 Dual brush DC motor driver expansion board based on L6206 for STM32 Nucleo Data brief Description The X-NUCLEO-IHM04A1 is a dual brush DC motor drive expansion board based on the L6206 (DMOS dual full bridge driver) to drive dual bipolar DC or quad unipolar DC motors. It provides an affordable and easy-to-use solution for driving DC motors in your STM32 Nucleo project. The X-NUCLEO-IHM04A1 is compatible with the Arduino UNO R3 connector, and supports the addition of other expansion boards with a single STM32 Nucleo board. The user can also mount the ST Morpho connector. Features Voltage range from 8 V to 50 V max. Phase current up to 2.8 A r.m.s. Direct output driving Mounting position for shunt resistors available Undervoltage lockout Programmable high side overcurrent protection Thermal protection shutdown Compatible with Arduino UNO R3 connector Compatible with STM32 Nucleo boards RoHS compliant July 2015 DocID028069 Rev 1 1/1 www.st.com For further information contact your local STMicroelectronics sales office Schematic diagram X-NUCLEO-IHM04A1 1 Schematic diagram Figure 1: X-NUCLEO-IHM04A1 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 VCP 7 6 NC 3 3 NC 2 2 GND 36 VBOOT GND VBOOT 30 19 GND 18 GND 1 EPAD 37 1 2 1 2 1 2 1 2 3 4 5 6 10 1 2 7 8 1 1 2 9 3 4 2 8 9 10 - 5 6 11 12 - 3 7 7 8 GND 13 14 - 4 6 9 10 15 16 - 5 5 11 12 17 18 - 6 4 ADC-6 13 14 19 20 GND 7 3 15 16 21 22 GND 8 2 17 18 23 24 - 1 19 20 25 26 1 21 22 27 28 IN1B 2 23 24 29 30 IN2B 3 25 26 31 32 ADC-4 4 27 28 33 34 - 5 29 30 35 36 EN-B 6 8 31 32 37 38 - 7 33 34 6 35 36 5 IN1A 37 38 4 IN2A 3 2 EN-A 1 GSPG060715 1135SG 2/2 DocID028069 Rev 1 CN7 CON-2x19 CN6 C4 220NF CN8 CON-1x8 CON-1x6 1x6 - pitch 2.54 D1 BAR43 C8 Radial 2 1 VS instead of 1x8 - pitch 2.54 C1 SMD R4 100K C5 EN-B EN B 10NF C3 C2 + C1 + C8 R6 100UF 100UF C6 NP R3 100NF 100NF 63V R5 100K 5.6NF 100R EN-A EN A R7 C7 NP 5.6NF 8 CN1 EN A 13 15 OUT-A+ 1 OCD A OUT1A A+ IN1A 10 2 A- IN1 A 5 OUT-A- OUT2A 11 U1 3 B- IN2 A J3 J1 L6206PD PROGCLA 9 4 B+ PROGCL A 22 OUT-B+ OUT1B IN2A 5 GND 29 32 OUT-B- 6 Vin EN B OUT2B J4 24 OCD B MKDS1/6-3.81 IN1B 26 3.81 IN1 B 12 SENSE-A SENSEA 27 IN2 B J2 PROGCLB 28 25 SENSE-B PROGCL B SENSEB IN2B R14 R15 YELLOW YELLOW YELLOW YELLOW R2 R1 D3 D4 D5 D2 NP NP 0R 0R R2512 R9 R8 5.1K 5.1K C9 C10 R10 R11 R12 R13 NP NP 10K 10K 10K 10K ADC-4 SENSE-B ADC-6 SENSE-A CN9 CN5 CON-1x10 CON-1x8 1x10 - pitch 2.54 1x8 - pitch 2.54 CN10 CON-2x19 - - - - - - - - - - - - - 3
