Kaboard

A Development board for Atmega8 or Atmega328 microcontrollers

Similar projects worth following
Kaboard is a development board for Atmega8 or Atmega328 microcontrollers.
It was designed for small one of projects or prototypes.

It's main features are :
- Onboard LM1117 voltage regulator providing 5v with 800mA
- All mcu pins broken out on pin headers
- Vcc and GND pins near every mcu pin, useful for supplying power to peripherals or for pullups or pulldowns
- ft232rl serial to USB converter
- It is not Arduino compatible

The components on the board were selected mostly, because they are cheap and easily obtainable at my local distributor.

Check the Github repo for more details and schematics.

You also have to try reading  http://excellent-essays.review/review-of-papersowl-com-writing-services/ because it will change the way you think. And I have no doubts about it. You are welcome!

How can it not be arduino compatible? o.O I'm using my old atmega8 perfboards with the arduino sdk now. All it needs is a 100nF capacitor between RST of the AVR and the DTR signal to bring the autoreset to work. Or do you mean by form factor for shields?

I like the GVS(Ground Voltage Signal) setup and I see a possible tag there!

Where were the boards made?

Yeah I basically meant the that the formfactor is not compatible.
The fact that you can run aduino sketches on it, is more an accident that could not be prevented.
Also the cap for resetting the board is already there, so you can use avrdude -c arduino.

The reason I mention incompatibility as a feature is because in my personal opinion arduino is nice way to get started with microcontrollers, but it should to point to stop.
I've seen many people building rather complicate projects stacking 5 shields on top of their arduino and writing like 50 lines glue code between the shields libraries.
If your aim is to get a somehow working solution quickly that's ok, but I usually look for more elegant and optimized solutions.
Also I do all my own stu... ehm ... boards.

The board where made at seeedstudio, the quality is ok for the price.

I thought I sensed the attitude and I was right :D I love arduino for prototyping and try to make my own "shields" instead (shield may not be right when using the nanos, minis and micros). But I have to admit that I have never had to use that many shields nor fabricate a product from my prototypes... I am always happy to save some time not inventing everything myself and shields give some time to focus on the software.
