Hello,When I plug this board to my computer, appears a removable disk of 1,6 MB capacity.Is this disk accessible from the MCU? For store small data, or make a dataloggerWhere the filesystem is stored? Neither the STM32F446RE nor STM32F103CB of the ST...

Thanks for your reply.It's for make a battery tester using different currents for different kind of batteries, drawing the discharge curve, calculating capacity and disconnecting when the battery voltage reaches the minimum voltage programmed.

Hello, I see in AN4899 some things:The diode marked in red in figure 1 prevents higher voltages than VDD+0.6V on a TT pin. For this reason, my design is not possible in TT pins.The NMOS marked in red in figure 2 has to withstand 12V (VDS) when is off...

Hello,I will tell you my short history with microcontrollers.I started with a Raspberry Pi bought around 2016. I made big projects with it, but there's no need a complete computer for most projects.Around 2020, I tried Arduino. I thought it wasn't ba...
