Hi all,

what breadboard IC's do you recommend for interfacing 3.3V (Arduino Due) PWM signals with 5V motor driver ?
I also have I2C, SPI, UART devices to connect.

Due is able to send 1Khz PWM signals . I have no schematics of the motor driver since I cannot find them online. Its the Riorand ZS-X11H .
Can I use mosfets to control break direction and stop from Due to driver? The driver provides feedback to calculate the RPM, would I be able to read it?
The reason I chose Due over other boards is:

1. a) I have a lot of devices (and probably will add more) and
2. b) Clock speed Due is twice as fast as my second choice (MKR1010)

I have done a research and posted this question in several forums including the Arduino forum but I still havent come up with a solution

 

I don't know why this should be so challenging. These and similar parts are not that hard to find.

Welcome to AAC.

That driver is from aliexpress.
I believe I saw that from there

 

Be careful with I2C because the SDA line must propagate signals in BOTH directions and requires the use of pullup resistors.

 

Is this it ?

The Site provides all the details how to use it. Dunno why you are having so much trouble with it.

 

I was able to use the driver with Arduino mkr1010 but since I need a lot of pins I needed Arduino Due.The reason that I am having trouble with it is because I'm not a pro and I would like to be sure that I have the right components before I spend hours/days soldering the wrong parts. I was looking for breadboard IC's
so:

1. what breadboard IC do you recommend for PWM?
2. what breadboard IC do you recommend for I²C?
3. what breadboard IC do you recommend for SPI?
4. what breadboard IC do you recommend for UART?

All components are 5V and the Arduino is 3.3V

thanx

 

For I2C I have beed recommended to use BSS138

 

hi y.a,
Any one of these types should be OK for level shifting.

I am looking for something like 74LVC245?
Can I use that for all signals?
what other IC's do you recommend?

 

This is a simple 4 channel bidirectional level shifter. You can find a schematic and tutorial here.

 

so I can use the above for all signals (PWM, SPI, I2C, UART)?
