Hi ,
I have a college project, for my undergrad thesis, where I needed to manufacture some boards, but manufacturing boards is way too expensive here, even for prototypes, 10 boards won't cost less than 300$. So I found this manufacturer from China, JLC PCB https://jlcpcb.com/. Honestly, I had a blast with their service, they delivered the boards in less than a week, it only took 2 days for manufacturing and 4-5 days shipping to registered post. The quality looks just great, as you can see in the pictures. It cost me only 2$ (100x100mm 10 pieces). They also sent pencils as gifts.
As a plus, they even have a online tool to design your PCB layout and export directly into their service and place an order quickly https://easyeda.com/.
The Project function :
I'm trying to control the volume with the 4053. A drawing like this helped. 4 devices can be connected. It has 4 indicators with leds. I used a tiny microcontroller. Like 16f616. I prefer to have a built-in oscillator. The card has an icsp connector. It has completely smd structure. It works with 5 volts. In the input 1n4007 is used as a reverse voltage protector. I'm thinking of writing your program with mikroc. I have not created yet, but I will add it in the summer. I will order prints through JLPCB and this will be my first order. The card dimensions are approximately 45mmx49mm. I was working on the breabord to try it. I will share the ISIS picture by editing the drawing. It's a bit mixed. Attached pcb pictures. I look forward to your comments.
