ODrive v3.4 with only one DRV8301

[habibzadeh]

Hello,

First of all thank you for this great work, I’ve made one sample PCB based version 3.4 of ODrive hardware because my intend is to use ODrive to control only one motor is it possible to assembly only one of DRV8301 and related Mosfets or both DRV8301 most preset for ODrive to work properly?

Thank you

Hi habibzadeh, another user got it to work without any firmware modification related to DRV8301. Please refer to this post.

Single Axis Integrated ODrive Concept

Only for the first iteration, because I took off the CAN IC (so I had to debug through the firmware and comment out any calls to CAN) so that was a nightmare. With my latest rev, which includes CAN, I hardly had to change the firmware. I only changed the firmware to update my shunt resistance values, the dead time clocks (due to me changing the low-side gate resistor values), and my tup.config file to v3.4-24V.

I am interested in your design. Do you have a picture?

I’ll publish images when I got it to works, thank u.
