WiFio - Mini

Hi Hackers.. It's been long, since the last update. Well, done with routing in last week but could not find time to post project log.. Here it is.

Ok ! There are few little changes.

Ohhh.. Wow.. Look at these 3D shots of WiFio.. Looks cool..

Do let me know your feedback... Thanks All..

Keep Hacking,,, Keep Innovating...

Ok Placement Done..

• Trying to Keep it as simple as I can.
• Paid attention to GPIO for easy access and interface for external peripherals.
• Form Factor as small as possible. Most of them are SMD.
• I guess need to update footprint for DC Barrel Jack, the one I have doesn't matches.
• Also I have noticed that Atmega328P-PU footprint from Atmel EAGLE Library, does not match with the device itself. It's quit ironic. Updated that too with couple of Trial & Error.

Undoubtedly, EAGLE is superior CAD tool, no matter How small or Big is your project. I have been using EAGLE for past 2 Years, And I still discover NEW things everyday.

MCU +3V3 Powerd | 8MHz Clocked:

28-PinDIP, for easy Plug-Play and Programming, In case You end-up burning one.

POWER:

LM1117 LDO for +3V3 Regulation and DC Power Jack which allows you to power the board over 9V/12V Power adapter.

GPIO:

As stated in details related board, Inspired from Real Bare Bones.

FTDI Header:

Simple and Easy USB-to-TTL interface for Burning sketches, Serial debugging.

ESP8266[ESP-01]:

+3V3 Powered Low Cost ESP-01 module. Easily available in electronics market or Online ebay/Amazon etc.

MCP9700:

Widely used in industry for Cold Junction compensation and other applications. Output in 10mV/DegC.

LDR:

Light Dependent resistor, See how easy it is to interface. On the next second you can start playing with it, building cool applications.
