I bought this CH340G USB to Serial converter module from PCBWAY Store. It is working nice. I have no issue with it. It can be connected with both the 3.3v and 5v logic level microcontrollers. The voltage is set by a jumper. I am very satisfied with the product.
This is the PCB Santa Claus I made for Christmas. As you can see it looks really cool. Way better that my Expectations.It'd look more cool if the surface finish was ENIG Instead of HASL. But that'd add up the overall cost so can't really do much about it. Nevertheless overall PCB, Silkscreen and all looks pretty nice, the cuts are clean and the details are also amazing.
Excellent built quality as always. Delivery took a little longer this time but it's OK.
This a neopixel 7 segment display PCB. it has ws2812b individually addressable RGB Leds. 2 leds per side so thats total of 14 leds. The board comes out nice. The built quality was amazing and the shipping time was also very fast. thank you PCBWAY for this awesome services.
