The new motor controller looks nice, but unfortunately the minimum motor voltage is 4.5V, compared to the 2.5 for the LB1836M. I am probably in the minority here for wanting to run GM10 motors from a single 3.7V LiPo, which the LB1836M does flawlessly.
Was the change made in order to get more current capability, or is there a problem with the LB1836M?
We like the new motor driver for several reasons: it delivers more current, works to a higher voltage (allowing the whole Baby Orangutan to work to a higher voltage), can be PWMed at a higher frequency, and draws less current internally. The low end wasn’t really limiting us because the AVR needs 4.5 V, anyway, at least to run at 20 MHz. However, we’ll continue to keep the single-cell Li/3-cell Ni users in mind for future products.
