We’re moving fast here! I really appreciate the time.
Great question. After being pretty badly burned on STM32’s over the last 24 months, I’m not able to make them an irreplaceable part of my products in the future. I’ve managed to secure a reel of RP2040’s, and they’re so inexpensive, I’d really love to use them if possible.
I think the right answer is that I would gladly use the ST ESC to prototype, but it would likely get swapped out later.
Ugh, I just learned why Mouser has those parts in stock. 1 per customer per month.
:-/
Any alternative (available) part suggestions for the motor drivers are welcomed, though the couple of driver IC’s I’ve seen floating around seem to be pretty hard to get at the moment.
We’re producing a SCARA-style robot arm. The arm is very lightweight (compared to similar robots), and our end effector is usually moving <100g loads, but it’s not quite light enough to use disc drive motors.
Though I do love the creative thinking!
I might be mistaken (please correct me if I missed something!), but I think the IPS2200 sensor only provides analog output. The SPI and I2C lines are only for configuration and error detection.
