This problem with the power stage is solved there is a solution with a new High power powerstage
The main problem at the moment is that some critical components like the 2 stm32 are not available (as of today there is a delivery date 10.03.2023) The stmbl uses some features of this stm controllers like the internet HIghspeed comperators and Shunt opamps. Hopefully there will be new stmbl as short as possible if the craziness of the chip market will normalise and you have not to pay something like 45€ for a stm32 > On 16.
