Hello,
I'm using an L298n H-Bridge board as found here:
I want to measure the current flow through the current sensing pin (pin 1 or pin 15). I saw for the l298n datasheet that I'd want to use a probe around pin 1 or pin 15, but I can't locate their location on the actual board itself.
Any help would be appreciated.
Isn't it obvious which pins are 1 and 15 on the IC?
If those pins are connected to ground, you will have to break that connection and add your own current sense resistor to ground.
If you see the schematic for the Arduino L298 Motor shield you can see the current sense resistors and the current sense amplifiers needed to provide a useable voltage to the Arduinos ADC input.
Using the module like you have the only way I could add current sense was to snip pins 1 and 15 from the pcb and fit a new wire to the pins to attach the current sense resistor/s and wire to the new amplifier/s.
