This post was last edited by Peng Binghao on 2019-5-7 21:07 DIY Modified Power Supply Current Display Digital Tube Preface : I bought a DC power supply. Before buying it, I talked to the customer service. I said that I liked this power supply very much and was satisfied with everything. The only thing was that the digital tube that displayed voltage was green , and the digital tube that displayed current was still green , I asked if there was a model with a red digital tube for current display? The customer service said: "No", "Will it be available in the future?" "No" Later, I couldn't persuade the customer service, so I bought this model with a drooping face. Text: Later, I was so angry that I bought a 0.56-inch red digital tube online and replaced it myself . There was a small episode. I bought a common anode digital tube, but the boss sent me a common cathode digital tube. Later, he sent me a common anode digital tube again, which made me get a dumb bargain without knowing why. . . I won’t say anything more, here are the pictures!

It would be more beautiful if there was a digital tube with adjustable RGB color

RGB is driven in different ways

It is well-made and beautiful. Pay attention to calibrate the digital tube and the actual voltage value when using it to eliminate the error.
