HB-25 dual substitution board $11.70!!!

Hey i found this on robotshop.ca! it's a dual motor controller with a motor prototyping area, it is controlled with PWM too! it's only $11.70! i don't think it's as accurate as the HB25 but it is definatly smaller! It also looks like you can use something like a dremel and cut out both the motor controller circuts. Each·one (of·2) is isolated on the other side! it's great for small robots that can be powered almost by a BS2 but just can't but it can go way higher too!·heres link: http://www.robotshop.ca/dagu-mr-basic-dual-2a-motor-controller-board-5.html·and heres a link on a awesome cheap little robot platform that has 2 motors with the controller: http://www.robotshop.ca/dagu-mr-basic-mobile-robotic-platform-2.html· (Looks like this platform would be great with a BS2 OEM module soldered straight to the protoboard!)

i was actully thibkin of soldering a 18 pin PIC to the board and all it's componets so i could prgram it directly from the board

Of course it's cheap, it doesn't do pwm on it's own and it doesn't have over-current prevention like the HB-25. Also, it has a max of 6v and 2 amps, so considering that is the equivilent of 12 watts and the HB-25 controls 16v 50a or 800 watts it has a difference in power output of 800 to 12. Not very good, is it? That means you would need 67 of those boards to rival the HB-25 in power output, and at a price of $11.70 it would cost $780.

it does support PWM, read the product listing on the site, even look at the picture there is a pinout named PWM for each

besides it is good for smaller motors

Of course it does! All relays and transistors support pwm. But which is doing it, your motor controller or your microcontroller? Also I thought I'd make mention that you could make the same controller yourself for under 2 bucks at 5 amps 60 volts if you wanted--you wouldn't get that nice board to solder to though.
