This HBridge v1.1 Unit is a DC motor drive module that is powered by the STM32F030 microcontroller and RZ7899 driver chip. It provides I2C communication with the M5 host, and accurate PWM control for speed adjustment and easy management of forward, reverse, and braking functions. Safety and reliability come first with built-in protections against over-current, over-voltage, and over-temperature. The module features a total power MOSTUBE switch circuit for dynamic motor control and an integrated current acquisition circuit for safe motor operation. It adapts to various needs with a smart 6-12V and 5V switching circuit, making it ideal for robotics, motor drives, industrial automation, and smart homes. Note: Aluminum electrolytic capacitors connected to the positive and negative poles of the power input can provide buffer protection for the circuit. Be careful not to connect them in the opposite direction Features * Overcurrent, overvoltage, overtemperature protection * Power switching * I2C address: Default 0x20 * Current Detect * Programming platform: Arduino, UIFlow Specifications Resources Parameters MCU STM32F030F4P6 DC bidirectional motor driver chip RZ7899 Current acquisition chip INA199A1DCKR External access DC voltage MAX 12V I2C mailing address Default 0x20 (can be modified by toggle of the encoding switch) Maximum allowable current 3A Use Temperature 0-40°C Product Size 48mm x 24mm x 8mm Package Size 136mm x 92mm x 13mm Product Weight 9.1g Package Weight 14g Resources * Product Wiki Package Contents * 1x Hbridge V1.1 Unit * 1x VH3.964P * 1x HY2.0 4-Pin Cable (20cm) * 1x M2 Hex Wrench * 1x 470uf aluminium electrolytic capacitor https://elecena.pl/product/26166442/h-bridge-unit-v1-1-stm32f030 2024-07-01 https://elecena.pl/product/26166442/h-bridge-unit-v1-1-stm32f030 2024-09-18 https://elecena.pl/product/26166442/h-bridge-unit-v1-1-stm32f030 2024-11-29 https://elecena.pl/product/26166442/h-bridge-unit-v1-1-stm32f030 2024-11-30 https://elecena.pl/product/26166442/h-bridge-unit-v1-1-stm32f030 2025-08-06 https://elecena.pl/product/26166442/h-bridge-unit-v1-1-stm32f030 2025-11-28 https://elecena.pl/product/26166442/h-bridge-unit-v1-1-stm32f030 2025-11-29
