X-STM32MP-RBT01

X-STM32MP-RBT01 is an X-STM32MP expansion board for robotics applications. This is an MPU expansion board with STSPIN948 motor driver IC for brushed DC motors. Using two STSPIN948 devices, board can drive four DC motors simultaneously with up to 48V power supply. The power rating of the board is 480W at 48V DC voltage rating with each of the four DC motor consuming a maximum 2.5A current. The X-STM32MP-RBT01 interfaces with the STM32MP microprocessor via 40-pin GPIO connector pins using I2C, UART, PWM, and GPIO connections for various components. The STSPIN948 is a 4.5A dual full-bridge driver for brushed DC motors. The power stage is designed with high dynamic performance, allowing to achieve high frequency PWM control with precise duty-cycle. The iNEMO inertial module ISM330DHCX has a full-scale acceleration range of ±2/±4/±8/±16 g and a wide angular rate range of ±125/±250/±500/±1000/±2000/±4000dps.
