I am attempting to use the SparkFun M7E RFID reader, with basic assembly and the library provided onsite. The module works perfectly fine with the USB connection via ThingMagic Universal Reader Assistant. But when it comes to UART, I only receive “Module failed to respond. Please check the wiring.”…

Are you sure the PL2303 is working. Else disconnect the M7E, connect Pl2303 TX and RX together and use a terminal program (like putty) to write to the port the PL2303 is connected. you should see an echo. Have you tried to use a USB-A <> USB-C ( PC <> M7E) cable, set the switch to USB, and use the…

[image] paulvha: URA Thank you for reply. I have already tried URA, could read tags. No problem. RXD LED is always lit, TXD LED is flashing when I enterd some keys from Putty. No response.

By the way, VIN and GND is short by via in PCB when I opened PCB by KiCAD. (This pcb file is not written by KiCAD, so something not matched? What type of CAD should I use? SparkFun_Simultaneous_RFID_Reader_M7E/Hardware at main ·... The SparkFun Simultaneous RFID Reader - M7E offers a si…

I could read using PL2303 and URA. [image] I used my Python file to controle M7E-HECTO via USB-UART. My program is wrong? will check.

The GND pour on the top layer does not connect to that via you indicated: [image] So no short from VIN to GND should exist. If you use a multimeter and find an actual short on an actual physical board, then there’s some manufacturing defect. The board was designed in Eagle, but looks like KiCad …

If you have program can perform well, could you provide me the source code? First, I want to read the version information by PC or M5Stack. This source code cannot work well. [image] GitHub - sparkfun/SparkFun_Simultaneous_RFID_Tag_Reader_Library: Arduino library to control the M6E-N…

That Arduino library is what I would recommend, because it has been tested and verified to function with the M7E module. Be sure to read the hookup guide closely: Arduino Examples - SparkFun Simultaneous RFID Reader - M7E Hookup Guide Specifically, make sure you change the module in the example fro…
