Customized products with highly integrated functionality. The cardiopulmonary resuscitation model control board is used to control the cardiopulmonary resuscitation model, achieve model functions, and meet the training requirements of students. Equipped with a high-performance M3 core microcontroller, it can drive four DC motors through two motor driver chips. Two motors are driven by 12V, while the other two motors are driven by 24V voltage generated by the built-in boost chip. Onboard 4-channel grating array acquisition port, used to identify the depth position of student pressing.
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/433MHz wireless control.
