Etching My Own Boards

Hi,

Any feedback would be appreciated before I send it off to be produced.
Attached are the Schematic and the Layout and will be updated as changes are made from the suggestions.

Using various entries in the Forum and using this as a starting point (thanks @THERICK), this is what I have...
http://forum.mysensors.org/topic/205/my-ideal-sensor-node-pcb/22

##Size##
5cm x 5cm

##Power##
If using 5V Regulated

• Use 5V Arduino Pro Mini
• Connect pins 1 and 2 on Jumper 1
• Connect pins 1 and 2 on Jumper 2
• VCC is 5V
• Install AMS1117
• +3V3 is 3.3 volts

If using 3.3V Regulated

• Use 3V3 Arduino Pro Mini
• Connect pins 2 and 3 on Jumper 1
• Connect pins 2 and 3 on Jumper 2
• VCC is 3.3V
• Install a jumper wire across IN and OUT pins labeled for the AMS1117 (Don't install the AMS1117)
• +3V3 is 3.3 volts
• No 5v sensors

Using Unregulated > 5V

• Use 5V Arduino Pro Mini
• Connect pins 1 and 2 on Jumper 1
• Connect pins 1 and 2 on Jumper 2
• Install the LM7805 (Vin pin on left, Vout pin on right)
• Use capacitors (C3, C4) as needed
• VCC is 5 volts
• Install AMS1117
• +3V3 is 3.3 volts

##Data Pins##
Right edge of the board

• Two digital pins on 3v3 with optional pull-up resistor.
• One digital pins on VCC with optional pull-up resistor.

Center of the board Mini Proto area (Columns from Left to Right)

• VCC
• Data pins (A0, A2, A2, D3, D5, D8)
• Independent holes 3 x 7
• GND

##Required Bill or Materials##
1 x Arduino Pro Mini (5V or 3V3 depending on the supply power and sensor requirements)
1 x NRF24L01+ 2.4GHz Wireless Transceiver
1 x Capacitor for the Radio across 3V3 and Gnd
1 x AMS1117 5V-3.3V Step Down Module (If NOT supplying 3v3 regulated power)

##Optional##
1 x 7805 + Capacitors if not providing regulated power
PCB Mount 3 Pin Plug-in Screw Terminal Block for Power In and Data pins on the Right side of the board
Female pin headers for the Arduino and the Radio
Sensors
Pull-up resistors

Panelized Gerber file sent to ITead: ArduinoMiniProBoard v2-Panel-Gerber 2014-11-04.zip [Order the 5cmx10cm board for $15, which gives you 10 boards you cut in half to make 20] (http://imall.iteadstudio.com/open-pcb/pcb-prototyping/im120418002.html).
Note: I was able to email them and ask to double the 5cmx10cm to the 10cmx10cm for $19 netting 40 boards. You would have to do more cutting. I was able to do it easily with a box cutter and a straight edge ruler.

Eagle Files: ArduinoMiniProBoard-v2-0.zip

11/24/2014: Tested v2 board and it is working. I have about 50 feet with 3 walls in between with not much failures. I need to see if caps will extend the range...
11/12/2014: Uploaded v2 Schematics and picture of the Board. Will post the Gerber files when I receive my board and they test OK.
10/31/2014: Found problems with the board.. Need to make a Rev 2 and retest.

The board tested good.

I have some small changes I would make for the next version but this board is good enough to start building...

The files are attached in the first post.
You you make enhancements, please share your enhancements so everyone else can benefit.

Thanks
Edward
