Simple electronic load

Overview

The operational amplifier collects the voltage on the current detection resistor and the adjustable resistor reference voltage division to determine whether to switch the MOS to realize the constant current discharge function. Limited by the MOS thermal power and thermal resistance, a single MOS can only If it can reach about 120W, the constant current effect will be lost (the detailed parameters are forgotten). It is recommended to be powered by battery. It is not limited to the load power supply. The cooling fan uses an NTC thermistor to detect the temperature and turns on.

Is it possible to write a string of user storage data to a section of flash without erasing it first?
I tried, without performing the erase operation, repeatedly writing different numbers in a space, the latter number can overwrite the previous number, isn't that enough? Why do we need to erase first
