Sounds about right retrolefty,
So there we go:
1-> I named board "PocketDuino". I know it's getting old this all about -inos... so this is just another -ino's being.
2-> I tried to get the smallest as possible and a fast to solder board, to be used in practice in the field (despite the slow of soldering jumpers). Board size is actually 6.1 x 3.8 cm (2.4 x 1.5 in).
3-> I tried to get a reliable design concerning power regulation and Aref filtering, to be used for sensors with more accuracy and in serious projects (Im not sure if I got success with the board in this regard, someone must tell me)
This is the board running: http://www.minasambiente.com.br/media/images/common/electronic/pdfinish.jpg
This is how im making the PCB: http://www.minasambiente.com.br/media/images/common/electronic/pdboard.jpg
This is a shield i developed for the PocketDuino: http://www.minasambiente.com.br/media/images/common/electronic/shieldp.jpg
(that's DS1307 RTC + EEPROM + ShiftRegister to control a parallel LCD -> Still under testings)
This is the schematics (component side): http://www.minasambiente.com.br/media/images/common/electronic/PD10.jpg
Blue lines are the not elegant jumpers.
I'm sorry about this schematic. I'm not proficient in Eagle, I did all the routings and drawings on AutoCAD and got not yet the representative schematics yet, I hope you can understand this schematic drawing.
The parts, from the schematic picture:
C1, C2 -> Electrolyct capacitor, 100uF, 16v
C3, C6 -> Ceramic disc capacitor, 100nF
C4, C5 -> Ceramic disc capacitor, 22pF
R1, R2, R3 -> Resistor, 1Kohm
I1 -> Atmega8, 168 (328??)
I2 -> Power regulator LM7805
LD1, LD2 -> Led 3mm
Q1 -> Crystal, 16Mhz
L1 -> Inductor, 100uH
That's. I will enjoy any constructive critics about the project or any other consideration.
I can host the AutoCAD layout for people interested in build own boards... so (ugh) let's consider this post the oficial release of PocketDuino project ;D
Sorry if I commit some bad grammar (english not my native)
