Trying to use a L9110s motor driver chip

[JT2]

I have this L9110S DC Motor Drive Module (https://www.amazon.com/dp/B0D17PJ2MS?ref=ppx_yo2ov_dt_b_fed_asin_title)
that has 2 L9110s motor drive chips on it.

I am trying to drive a little top motor and control this from an Arduino nano. I have the arduino drive 2 outputs, one high and one low, with these connected to IA1, IB1 and the motor connected to OA1,OB1. Nothing happens, however if I connect a ground to either IA1 or IB1 the motor will turn on. Very odd...

Anyone have experience using this device?

Anyone Used The L9110S Motor Driver Chip?

The L9110S motor driver IC (click for data sheet) looks interesting for an application I have. I have 2 groups of 4 LEDs to control. Currently, a pair of micro pins control a high side switch for each group of LEDs. All of the anodes are connected in common to an n-channel mosfet controlled...

What voltages are you using?
Do you have the Arduino ground connected to the driver module ground?

With the outputs permanently set high & low, what voltage do you get on the module inputs?

Good questions, let me check

The L9110S is decent for basic motor control, but if you're planning to expand into wireless or IoT-based motor control, integrating a module like the EM3586-RTR could be a great step. It combines Zigbee connectivity with low power consumption, making it ideal for remotely controlled or sensor-integrated motor systems.

Hi, any update?
