STM32 series core board and universal expansion board

Overview

Current main projects
Sensor sample has been applied for and is waiting for testing
The first purpose of this board is to read ambient temperature/open solenoid water valves and 220VAC equipment control
The board is powered by batteries, so it needs to run with low power consumption. The STM32F series is not a low-power series, so it can only use standby mode to save power as much as possible.
By the way, let me complain: The STM32L series (that is, the low-power series) is too expensive. I hope that domestic MCUs can provide configuration software similar to STM8/32CubeMX for generating BSP like STM.
Using version management, sensors, actuators, and gateways have corresponding versions.
Sensor/actuator controlled by STM32F030C8 chip and gateway application board controlled by STM32F401CCU6/STM32F411CEU6 chip
Available/simultaneous use of nRF24L01+ and SX1278 modules to transmit data
The sensor is a temperature sensor node by default. For other types, please use the 4P module to expand
Optional EEPROM for data/instructions storage
Optional charging function
