My main interest lay in the area of computers and software but with the discovery of the Arduino platform I was able to merge the two together.
I've bought a few pieces of hardware from various sources and had a dabble at making my own hardware (mainly
Anyway I decided I needed a project of my own to get my teeth into, I wanted to learn how to use the Eagle schematic capture and PCB layout software and after discovering Seeedstudio and their very keenly priced PCB manufacture, I decided to make a general purpose PCB that would allow me to tinker with both the ATMega 328 and the ATtiny84 processors along with various extras.
This board isn't aimed at a final solution but more an electronics breadboard much like the old Tandy electronics kits I used to play with many, many years ago.
- Independent ATMega328p and ATtiny84 on the board
- Each having its own RFM12B and ISP programming connector.
- Twin power supplies, 5V and 3.3V with the option of using a CR2032.
- A series resistor option for measuring supply current, jumpered out if not required.
- A prototyping area.
- A 4 port layout like the Jeenode (so I can plug in my GLCD).
- A RTC (DS1307 3.3V)
- Two I2C ports connected to the 328P with 5V and 3.3V (should work with Jeelabs plugs)
- FTDI connector (328p)
I've not ordered the PCBs yet as I'm fine tuning the board still but should be doing it in the next week or so.
