Building a minimal XBee Device with an Arduino Pro onboard.

All pins of the Arduino (except XTAL1,XTAL2 of the Atmega 328) and the XBee are provided on the headers, which have a standard 2,54mm spacing.

The Arduino and XBee are only sharing the power supply. If connections are needed between the XBee and the Arduino (e.g. TX/RX) or anything else ,wire bridges can be made between the header pins. 

The board has SMD/SMT parts. Solder paste and a Hot Air SMD Reworkstation was used for Soldering. The Trick is to use as little solder paste as possible. I applied the solder paste to the Board cleaned the pads with the top of a scalpel.

 

Parts used (Digikey Numbers):

ATMEGA328 (ATMEGA328-AU-ND)

XBee (602-1098-ND)

LDO SPX3819 (1016-1248-ND)

CER RESONATOR (490-5994-1-ND)

LED (L71504CT-ND)

 

Capacitor (478-1557-1-ND)

59Ω Resistor (P59.0FCT-ND)

10.2KΩ Resistor (RMCF1206FT10K2CT-ND)

Switch (EG4622CT-ND)

Tantal Capacitor (399-10116-1-ND)

 

 

The Power supply has a current output of 150mA. Next time I will use a SPX3819(1016-1248-ND) which can output 500mA.

 

Update: The SPX3819(1016-1248-ND)  works better and was added to the part list as a replacement for the LDO (576-1259-1-ND).

I used to do that myself to. I used to learned that in my old job. I dont do that anymore because of the chemical and the surface mounted stuff(repainting the wires...). But of course that price can not be beaten :)

I Slovak so my English is poor. Interested in my way PCB fabrication? I use a mask and photoresist from eBay said it is low quality but I learned much with the robe with that the fed can be miracles and is little need for paint so it's very economical method. I had the exact procedure described on my site but due to lack of visitors has been deleted. If you are interested in a detailed manufacturing procedures please write.

Hi SimonHosa. Hope I understood you correctly. 1. He had to produce this PCB company Fritzing? No I didnt need to produce this at Fritzing. It was my choice, because I like the quality I get from Fritzing. 2. Worth € 6? For me it was. What worth means is a personal choice, and decided for me it is worth. Also you can download the fzz for free. So you can do whatever you want with that file, based on what is worth for you. 3. I also manufacture the development and costs € 0.20 I barely even from the mask and description. If you can do this for 0.20€ Im very interested in your workflow and production. As I mentioned in 2 the fzz is free. The rest is up to anyone else. Summary: This was just to get a reliable pcb at the first try and for me It was worth the 6€. This was not about going as cheap as possible it was more about the size I needed. Also when you order something at fritzing, they will use some amount of that to develop that fritzing software! I like to pay for software if that means they can add features. Best regards holzmolz
