Hey there! I’m looking to play with haptic feedback on one of those GM3506 gimbal motors, and have some fun ideas that would require accurate torque sensing. I believe I need accurate current sensing for that. What hardware would be best for this use case?
The B-G431B-ESC1 looks like a great board, but seems to lack native SPI pins broken out for the AS5048A encoder. Is there something that does tick all the boxes out there?
For future reference to anyone with the same question:
I ended up purchasing an STM32G474 Nucleo (a platform I’m familiar with, with lots of processing power, that seems to well supported by SimpleFOC)
And an MKS DUAL FOC PLUS, which has current sense amplifiers and shunts, so I’ll be able to decrease the current sense range as needed to get a high enough resolution for what I’m planning.
I considered the SimpleFOCV3.2 as well, but I preferred the current shunts over the fixed gain / noise ACS712s.
Here’s a link to the board: https://www.aliexpress.com/item/1005005066500496.html
