2 connections for 5V servos connected to the high-resolution dedicated timer – no jitter!
4 H-Bridges: TB6612 chipset provides 1.2A per bridge (3A peak) with thermal shut protection, internal kickback protection diodes. Can run motors on 4.5VDC to 13.5VDC.
Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5% resolution)
Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping
. Motors automatically disabled on power-up.
Big terminal block connectors to easily hook up wires (18-26AWG) and power. Reset button brought up top.
Polarity protected 2-pin terminal block and jumper to connect external power, for separate logic/motor supplies.
Instead of a L293D darlington driver, we now have the TB6612 MOSFET driver: with 1.2A per channel and 3A peak current capability. It also has much lower voltage drops across the motor so you get more torque out of your batteries, and there are built-in flyback diodes as well.
