Qunqi L298N Motor Drive Controller Board Module Dual H Bridge DC Stepper for Arduino

Q: why's it got a pencil sharpener on the top?

Because it wouldn't fit on the bottom.

Q: What are those blue connectors for? Can I see a connecting diagram or instructions of some sort?

The blue terminal blocks are for power connections. The 3-term block is for supply voltage, ground, and +5V out from on-board regulator. Each 2-term block is for a power circuit to a motor (voltage is same as supply). A search online for "l298n driver module" images gives a lot of useful connection diagrams. ST Microelectronics provides good technical documentation for the L298 IC, itself, which describes the power limitations.

Q: I lose the voltage from 10v to 4.5v, as soon as I connect to motor controller. Any idea why it is happening and how to correct it?

I need a bit of context for your question. are you using a microcontroller with the L298? How many motors are you using? do you have a separate power supply for said source of controls? Are you using an arduino?

Q: Is there a way for me to detect a stall using this driver?

No, there is no feedback from the motor to the driver. Possibly monitor the current used by the motor with a Hall Effect transducer and, if it exceeds a certain value, consider it stalled.
