Hi,[/size]I am in need of a high current multi-channel PWM control board(3A each channel). But need help on which approach to go:First approach:Get a DMX Master Controller(either buy one or build one) and buy those dmx decoder from china manufacturer for a good price. Example:http://www.alibaba.com/product-gs/458012100/T_840_led_rgb_dmx_decoder.html Most standalone DMX master is too costly, I am planning to build one myself with Arudino. Not sure if it will work as good as those few hundred bucks standalone DMX controller out there. Please suggestSecond approachesign a multi channel high current PWM switching board. I have yet to decide which IC to use for this. I need at least 10 channels of PWM. Planning to go with MOSFET for the power section. But some people suggested transistor is better choice for this scenario. What do you think I should use in thise case?
