What is kaboard ?
|
|
||||||
-----------------
|
|
||||||
|
|
||||||
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, usefull for supplying power to peripherials or for pullups or pulldowns
|
|
||||||
* ft232rl serial to USB konverter
|
|
||||||
|
|
||||||
The components on the board were selected mostly, because they are cheap and easily obtianable at my local distributor.
|
|
||||||
One exception is the ft232rl.
|
|
||||||
Many fellow hackers told me, that an Atmega with integrated USB would be cheaper and could be used for more then just RS232 over USB.
|
|
||||||
I decided to stick with the ft232rl for 2 reasons :
|
|
||||||
* It's easy to use a serial bootloader like optiboot, that doesn't eat up much flash, for programming.
|
|
||||||
There is even the possibility to use the a pin of the ft232 to reset the mcu,
|
|
||||||
so even with a crashed programm you can switch to the bootlaoder, without pressing buttons on the board.
|
|
||||||
|
|
||||||
* Whenever I used usb so far I needed a simple way to exchange a few bytes between a mcu and a computer.
|
|
||||||
Emulated RS232 is usually sufficiant for this.
|
|
||||||
I've allready looked into the LUFA USB stack and I've played with usb on the stellaris launchpad.
|
|
||||||
Afterall I've come to the conclusion, that an extra chip like the ft232 provides a more selfcontained
|
|
||||||
and also easier to use implementation for RS232 over usb.
|
|
||||||
Also I learned the hard way with my steallaris launchpad, that a usb can be a real pain in the ass when it comes to debugging it.

What the !/%§)"" does KaBoard mean ?
|
|
||||||
------------------------------------
|
|
||||||
The name is actually inteded to be pun for german readers.
|
|
||||||
"Kaputt" is german for broken (or as dict.leo.org told me for kaput).
|
|
||||||
In the palatinate dialect this word pronouced rather "Kabutt" or even "Kabudd",
|
|
||||||
which sound similar to KaBoard.
