Hello again.
Ok, so I need to start getting some ideas for the small project, which is big to me due to my inexperience.
The goal is to project and build a small fan controller, using any STM31L0 chip.
It will be used with a RockPro64 board.
The idea is to cool down a NVMe drive I'm using on the RockPro64 board, by monitoring it's surface temperature with an IR temp sensor.
To summarize things, I'll state the parts I have (and want) to work with.
Temp Sensor: GY-906 (MLX90614)
uC: any STM32L0
Fan: Revoltec Air Guard
Initial limitations:
The fan ratings are 12V, 70mA
MLX90614 is 3V or 5V.
The STM32L0 is 1.8V up to 3.6V
So, to start, I want to put this on a small PCB or at least solder all components by hand on a through-hole board.
This said, I think the first thing I think I need to think about is that I need to lower the voltage from 5V or 12V of the RockPro64 to the required voltage for this STM32L0 chip.
What else I should be thinking about?
(maybe I don't need an voltage amplifiers or current amplifers, etc, but we'll see later).
PS:
Maybe this should be moved to the projects section
