Range Test, Constant RFID read) but I am unsure of how to adapt the library to address my specific case. Even screen was not able to pick up anything from the reader... thought maybe it would talk a bit during boot... nothing... nada...Am I assuming correct that the UART on the serial port of the reader is 3.3 V logic level? I want to use it on ESP32 board.ELEGOO UNO R3
Other models get more but that's with their internal antenna.Can anyone confirm that this board actually works with the Universal Reader software? Please check wiring." How far distance the reader can read the tag?I just did a little bit of unscientific testing with mine, and with the power set to 500 centi-dBm (i. e. 5 dBm), and using the built-in antenna, it appears that the tag has to be within 1 centimeter of the PCB antenna to read. The first screen will give you a list of all shipping options for your address as well as their costs. So far I was able to compile them in mac osx and rapsberry pi with @ppelleti guidance...I can read a tag from over 5 meter away using a 80mm ceramic antenna.This was exactly what I need.
Wish List! I spent a few extra minutes removing solder unnecessarily because I thought I had accidentally bridged a connection between SJ1 and SJ2. With the SparkFun tags, I've found that read range is best when the long axis of the tag is parallel to the long axis of the reader board. They don't like being right next to your hand - read range seems to drop.I also suspect, but haven't proved yet, that power cables near the reader may reduce range, and that the quality (e.g. "I am not harsh but unfortunately, it worked well and produced good results for 2 hours and suddenly the board is dead, no response at all. Also when we order from India, we end up paying 100% import duty that is a bit hard.I am willing to come and change this rating as soon as I receive the latest order and it works for me. My project that I used this for was to use python in a Raspberry Pi to interface with this reader using an external antenna up to a distance that would cover a normal traffic lane. In theory you could drive 9/10 at alternating frequencies doubling the volume of the buzzer.Can anyone recommend a specific model of heat sink (e. g. Digi-Key part number) for use with this product? We where thinking about RS485 bus but if you know better option :p Are you using a SparkFun sourced tag? It seems that the RFID reader randomly scans for any tags, often reading the same tag multiple times. https://www.elegoo.com/product/elegoo-mega-2560-r3-board-atmega2560-atmega16u2-usb-cable/ESPr - One - 32 (Japanese site) These three pieces fit into a process where: Data is first stored in an RFID tag in either a read-only or read-write format. Don't forget to buy the Interface Cable RP-SMA to U.FL (WRL-00662) if using the external antenna, it was not listed in the Hookup Accessories.It's missing the cable for the larger antenna, and it's NOT listed as 'recommended' have not tested it because of this. Please do let customer service know and we'll get any missing parts right to you.Got mine. Please maintain attribution to SparkFun Electronics and Oregon State University OPEnS Lab. It just hangs and so is useless. SparkFun Simultaneous RFID Tag Reader - NANO M6E (SEN-14066) This is a powerful shield capable of reading multiple RFID tags at the same time. So if you find yourself lacking distance it is something to consider.PARTS I USED LIST: As mentioned earlier, I will bring this up for future design considerations.Here are some alternative options:
I guess EPCGlobal GEN2 standards have changed since 2005 when my old tags were manufactured. I verified the firmware to be 1.7.1.2 and was able to read tags without an issue.Next I used the Example2_Read_EPC that comes in the library. I'm waiting for arrival of an external antenna to see what range it can manage.It often depends on what kind of tag you are attempting to read. All orders do ship with an invoice and you will receive an email conformation with it as well.
