TDA2030A, C4793 & A1837 Dual Ch Amplifier.


Hello Friends, In this post I make a 80W stereo amplifier using TDA2030A IC and C4793 & A1837 Transistors, which can deliver up to 80W RMS output at 4Ω ±16V. The sound quality of this amplifier is very good. All frequencies are very clear. You can make this amplifier at a very low cost, and you can get good quality sound. For designing my PCB, I used EasyEda online software. And then I go to PCBWay to manufacture my PCB. PCBWay is the largest PCB manufacturer in China. They offer Standard PCB, Advanced PCB, Rigid-Flex PCB, SMD-Stencil, and PCB Assembly Services. Here you get, 100x100mm 2 Layer PCB only at $5, And processing time within 24 hours. And they distribute, worldwide. The more you order, the less price you have to pay. You must upload the Gerber File and select the quantity, color, silkscreen, thickness, etc. Then choose your country, and shipping method, and then Pay. PCBWay will deliver your PCB within 7-10 days.


The PCBWay 7th Project Design Contest, launched in September 2024, promotes creativity in electronics and mechanical design, with an added emphasis this year on STM32 projects. The contest allows participants to submit their work in three categories: Electronics Projects, Mechanical Projects, and STM32 Projects. These can range from simple circuits to complex 3D mechanical designs.

Key deadlines include a project submission window from September 2, 2024, to January 19, 2025, followed by a review period, with winners announced on March 10, 2025. The competition encourages open-source designs and looks for projects that are both innovative and socially significant. The prize pool includes cash awards, with additional prizes for STM32-related projects and popular designs.

Participants have the chance to win up to $1500 along with various electronics gadgets, such as Raspberry Pi 5 and specialized hardware tools. All approved entries also receive a Raspberry Pi Pico as a participation prize.

The competition is open to electronics enthusiasts and innovators, with clear evaluation criteria focusing on design complexity, project descriptions, and social impact. It’s a great platform to showcase cutting-edge ideas and gain recognition in the global tech community.


After one week I received my PCB. You can see the PCB quality, it's awesome. I ordered Yellow PCB. But you can choose your PCB color. PCBWay provides 9 color solder masks - Green, Blue, Red, Purple, Black, White, Yellow, Matte Black, and Matte Green. On PCBWay you can get 100x100mm 2 Layer PCB only at $5. Maximum size PCB you can get 500x1100mm. The maximum Layer is up to 14 Layers. If you order PCB for the first time at PCBWay, you get a $5 discount coupon. So upload your Gerber today and get the best quality PCB.
