With the development of technology, our products are constantly upgrading. In order to better meet customer needs, we upgraded the flashing light control board from V19 to V20, let us explain the difference between the two in detail.
In the V19 version, a digital transistor is installed with two built-in resistors. The current maximum current is 500mA, and it cannot be replaced with a higher current transistor. In the updated V20, the digital transistor is directly replaced with two resistors + MJD122, and the maximum current is increased from 500mA to 2A. In addition, a diode and a capacitor have been removed to maximize the space optimization.It's also more convenient to use.
