RFID-125KHz-UART reader

I need a reader for 125KHz cards and fobs.

Read very carefully: line by line until the end.

If you do not know to work with Eagle PCB, no need to apply

If you do not know how to calculate and design a PCB antenna, no need to apply.

It MUST read card or Key Fob EM4100 format.

Must work on 5 volts DC.

Output must be UART or WG Wiegand selectable by jumper.

Separate led output when a read is completed = pulse

Your task:

Select the reader chip.

Make the schematic

Make the PCB layout on eagle.

Calculate the parameters for PCB Antenna.

Make antenna on PCB.

Look here like Mikroelektronika made a PCD antena

[login to view URL]

Mikroelektronika used EM4095 which has output as WG Wiegand. It is OK

On datasheet of EM4095, at the end is the instructions and formulas for the antena.

Read here the application note for EM4095 and PCB antenna calculation

[login to view URL]

At the end of aplication note it is the schematic and all the components with the value used.

No need to reinvent the wheel.

The distance to read is not important, as the card can touch the antenna up to 3-4 cm.

I am not interested on your Master or Doctor skills on Programing C/Arduino/Python and so on.I am interested to read the data sheet of EM4095, put on schematic the few components.

Make the board, and ANTENNA on the board.

Have the connection points with a external microprocessor.

Outsource where to buy the chip.

If you can find a different chip which can output UART also it will be better.

Also, i prefer a newer chip which works on 3.3 volts if it is possible.

Stop making proposal because you worked in a space shuttle.

I am not interested in more skills than what i explained.

If you tell me the story of you life, i will delete the proposal and not read it.

Hello. I have experience about PCB with Eagle. I prefer Atmega8a chip. You need board antenna of EM4100 like EM4095. I can calculate atenna factor by reference to EM4095. Regards.
