The circuit board is compatible with the same family of controllers and displays.
The POWER module provides POWER for the whole CPU module, the GPRS module, the IC15 module and the accessed sensor, and is in one-to-many single-item transmission relation.
When the GPRS module is externally connected, the GPRS module and the CPU are in a multi-way connection mode, data communication adopts an RS232 serial port two-way connection mode, the startup and shutdown operation adopts one-way control, and the CPU can control the startup and shutdown of the GPRS module through an IC 15; the CPU sends the integrated data to the Ali cloud through the GPRS module through the IC14 and peripheral circuits thereof. The GPRS module feeds back data issued by the Aliskiren cloud to the CPU through the IC14 and the peripheral circuit module thereof.
Specifically, as shown in fig. 1, the IC2 and the IC1 are connected via VBAT nodes, which mainly provide real-time clock and data backup power for the IC 1.
Further, the starting circuit is connected with the IC1 through a BOOT0/BOOT1, and the main function of the starting circuit is to control the starting mode of the IC 1.
Furthermore, the programming download interface is connected with the IC1 through PA13/PA14/NRST 3 signal lines and 2 power lines, and the main function is to program the IC 1.
Further, the crystal oscillator circuit is connected to the CPU through OSC32_ IN/OSC32_ OUT/OSC _ IN/OSC _ OUT to provide the necessary clock frequency for IC 1.
