Customized products with highly integrated functionality. Abdominal palpation model control board, used to control the abdominal palpation model, achieve model functions, and meet the training requirements of students. Built in high-performance M3 core microcontroller, capable of driving four DC motors through two motor driver chips. The motor output terminal is equipped with a self recovering fuse to prevent motor blockage and circuit board burnout. Onboard 10 channel external low-level trigger input point, used to identify the student’s pressing position.
Built in 4MSPI flash memory is used to store model operation and case sounds. Built in voice circuit, reads specified voice segments from the built-in flash memory according to the instructions of the microcontroller, and outputs them to the speaker through the onboard amplifier circuit. It supports a maximum of 4 ohms and 3W full frequency speaker. The main power supply uses a 12V2A input and a built-in power conversion circuit to convert it to the required voltage. The control mode supports 485 bus control and 2.4GHz wireless control.
