Hello, I got this kit last month and experimenting with the range. I find the range is maximum of 5 feet (in a particular direction only) when powered from external power supply and the read power set to 15dBm. Before I experiment with external antenna I wanted to explore and understand the beam width, gain, directivity and other details of the PCB trace antenna. So I have following question. What is type of PCB trace antenna used in SEN14066 SparkFun Simultaneous RFID Reader - M6E Nano ? Can anyone point me to the datasheet of the PCB trace antenna used in SEN14066 ? Thanks in advance
I'm curious... Is it safe to assume that it can read a particular tag multiple times while a Frisbee is airborne? Does it take into account that a single tag could have multiple RSSI values depending on the timing of the read or is the tag just read once and wherever the frisbee happened to be at the moment is the RSSI that is recorded? I'm looking into using this module for inventory purposes and just want to understand how it works.
Hi, I bought SparkFun Simultaneous RFID Reader - M6E Nano for a project. I powered it up with the Arduino Uno, did not attach any external antenna Just the Interface Cable RP-SMA to U.FL and the distance I am getting is just some inches. Help required to do the distance test.
I had exactly the same thought. Looking closer at the photo of the board, I see that there is a tiny U.FL antenna connector. Now looking for an antenna geometry that could work for automatic finish-line detection in a foot-race (marathon, etc.)
SWETTY hit the ARDUINO BOARD + RFID SENSOR BOARD for the win!!!! And the other guy on the audio said (OH WHAAAAAATTTT!!!)... can't believe his eyes. It seems that the ON-BOARD antenna of the RFID sensor was not bypassed by the HIGH GAIN ANTENNA. If that is the case, then the BOARDS should have been placed at the back of the HIGH GAIN ANTENNA...
Hi huys, very interested, If it is connected to an arduino compatible board , could it be power up to 27 dBi? what type of antenna connector does it have? I did not see it on the pics.
Hey! You probably shouldn't turn it up to 27dBi while powering it through the Arduino's power connector (and voltage regulator) but you could supply an appropriate 5Vdc source to the shield itself through the battery pin. Running at full transmit power, the module will probably require an additional heatsink and possibly active cooling. it's a small part and that's a lot of energy.
Thanks for you reply, nice piece of hardware, for applications where not much power is require and not many tags to read, it could be an inexpensive solution.
It is possible that his wasn't the closet, but actually just the closest that was also most in-plane with the antenna. For what it's worth, though, a few of us were able to consistently predict the winner based on just watching the frisbees. In other words, while signal strength isn't _always_ a great indication of distance, it almost always lined up with our observation. The fact that this module was able to pick out a dozen spinning tags whizzing past the antenna still blows my mind.
Are you sure that it read a dozen? i can only see maximum 2 different readings... I'm planning to buy this board and to read simultaneously a lot of tags... I read somewhere that it doesn't work as expected
It's steep, granted, but I'm afraid there's not a lot we can do. The module itself comes in well over $100. Until someone develops a less expensive alternative, we believe there are people who will pay a premium for hardware, documentation, support and the opportunity to play with a cool thing.
If you're really interested in it, you can always purchase the parts and build your own. SparkFun has all the design documentation (including PCB layout) on their website. But the cheapest retail place I could find to purchase the module apart from SparkFun was $125. By the time you add the other components and PCB printing, you're probably not going to save much.
I *just* bought some RFID stuff from you guys. Haven't even received it yet and you guys come out with this! I'll be ordering again...
Awesome demo guys :-D
Lol - the one Swetty won the frisbee that actually bounced off teh antenna was blue. The one he showed was yellow.

How did you program the game?
I'm curious... Is it safe to assume that it can read a particular tag multiple times while a Frisbee is airborne? Does it take into account that a single tag could have multiple RSSI values depending on the timing of the read or is the tag just read once and wherever the frisbee happened to be at the moment is the RSSI that is recorded?

Doggoze like discs. Doggoze also get confused when so many are flying by at the same time!
What are you using for the external antenna? I'm wondering if a directional antenna could be used in a race-timing scenario?
I had exactly the same thought. Looking closer at the photo of the board, I see that there is a tiny U.FL antenna connector. Now looking for an antenna geometry that could work for automatic finish-line detection in a foot-race (marathon, etc.)
Richard Crowley did you find a suitable antenna for this?
Looks like this antenna. www.sparkfun.com/products/14131
UHF RFID Antenna (RP-TNC)

what is the reading range of the RFID reader can it atleast the tag at 2 feet distance please reply guys and can it read the multiple tags at a time?
What is the range of the antenna?
This module doesn't seem to read simultaneous tags while reading UID.
Wonder if the code is able for sharing !!
i am trying to use the same thing but i can't found something like that on your code Example
may i know the buffer size of this rfid reader.
Can we use it to read Passive RFID Cards?
Did any dogs trying fetching the Frisbee and running off with it?
The dogs were completely flummoxed. They just couldn't believe we weren't throwing the frisbees to them.
But how many fribeees were harmed in the making of this video?
I've been advised not to comment on the condition of any frisbeeees associated with the project.
How About using it With Raspberry Pi ? Does this reader Works?. Please Reply ASAP. Thanks. More Power
What if I will not use an antenna ? What is the current range of this reader?
Hi huys, very interested, If it is connected to an arduino compatible board , could it be power up to 27 dBi? what type of antenna connector does it have? I did not see it on the pics.

But Swetty wasn't the closest.
Yes he was. Look at 2:45. His is the red frisbee with the yellow top. Look again at 2:51. He gets a direct hit on the pole.
It is possible that his wasn't the closet, but actually just the closest that was also most in-plane with the antenna.
For what it's worth, though, a few of us were able to consistently predict the winner based on just watching the frisbees. In other words, while signal strength isn't _always_ a great indication of distance, it almost always lined up with our observation.

What's he wearing?
Are you sure that it read a dozen? i can only see maximum 2 different readings... I'm planning to buy this board and to read simultaneously a lot of tags... I read somewhere that it doesn't work as expected
Seriously. What is that suit he's wearing?
first
$200 come on guys, I was thinking of buying this product but now, naah

The commercial equivalent is $800 for a cheap one. This is a impressive device
Useless demo
