First, every electronic project start small, but sometimes current is not enough, so many circuits work fine at 500mA, however real loads like motors, leds and power modules need more current, so instead of redesign full system, we can just boost current using a smart add-on circuit. Next, this External Current Booster Circuit using Transistor […]
