The 9V adapter gives 9.5 V with no load. When it is used to power a TXT controller, it drops just around 5 mV. The "9 V Out" pin, on the other hand, gives around 8.5 V. When an encoder motor (part # 153422) is connected to it and turned on with Robo Pro, the "9 V Out" pin drops just a little bit: 8.4 V. The tension is around 7.7 V across the motor terminals.
On the other hand, an L298N module connected to an Arduino Nano gives 8.1 V across the motor pins. That's a bit of a surprise, because this module is considered antiquated by many people because it uses bipolar transistors.
In the end I don't want to use the L298N's because they are quite bulky. I have some other drivers like the BA6418N and the L293D. I also have a pair of L9110 modules, but as far as I know they don't have a brake function (important for encoder motors), and they also get super hot. I suspect none of them would be the recommended choice for today. I was thinking about a FET driver, but I'm not sure at all. (I'm familiar with electronics, but just as a hobby.)
So here's my question: which would be the best motor driver for ft motors?
Thanks in advance for any answers.
P.S. Sorry for no German translation this time. I'm pretty sure Google will think I mean a "motorcar driver"
