*4. The
main control N32G430C8L7 microcontroller product of the hardware part adopts a high-performance 32-bit ARM Cortex-M4F core, integrated floating-point unit (FPU) and digital signal processing (DSP), and supports parallel computing instructions. The maximum operating frequency is 128MHz, with up to 64KB of on-chip encrypted storage Flash, and supports multi-user partition authority management, and supports 16KB of embedded SRAM. It has a built-in internal high-speed AHB bus, two low-speed peripheral clock buses APB and bus matrix, supports 40 reusable I/Os, provides a rich high-performance analog interface, including a 12-bit 4.7Msps ADC, supports 16 external input channels and 3 internal channels, and provides a variety of digital communication interfaces, including 4 U(S)ARTs, 2 I2Cs, 2 SPI/I2S, and 1 CAN 2.0B communication interface. The N32G430C8L7 microcontroller product can work stably in the temperature range of -40°C to +105°C, with a supply voltage of 2.4V to 3.6V, and provides a variety of power consumption modes. This case uses few resources, and the internal clock has been open source to meet the design requirements, so there is no need for an external clock circuit. It should be noted that each power pin of the chip needs to be connected to an additional 100nF external filter capacitor, and the 1st pin of the chip needs to be connected to an additional 4.7uf filter capacitor.
30v to 5v 100ma wide voltage input, up to 30V input, 5V output, maximum 100ma.
Independent buttons 6 independent buttons, capacitor debounce. PWM-IO port drives transistors and solid-state relays. Dual-channel PWM output, can control up to two heaters, or other high-power devices, the driving power depends on the load capacity of the solid-state relay.
