Proxmark3 Easy from Taobao thoughts?

I'm thinking of purchasing the Proxmark3 Easy from Taobao (https://world.taobao.com/item/530178074292.htm?spm=a312a.7700714.0.0.njq65w#detail) and was wondering what the limitation of this was compared to normal Proxmark3s?

I need to clone my apartment key (DKS/Idteck) which appears to be 125khz with PSK/or modified PSK modulation and was wondering if this item would do the trick.

Re: Proxmark3 Easy from Taobao thoughts?

Hi.
I received mine today.
I've already a few "old" proxmark3 and in comparison I must admit this one rocks!

  • very compact design, including LF & HF antennas

  • antennas tuning is very good, see below

  • the pcb can be held without being afraid to shortcut or disturb RF parts

My device:

# LF antenna: 32.04 V @   125.00 kHz          
# LF antenna: 27.50 V @   134.00 kHz          
# LF optimal: 35.75 V @   127.66 kHz          
# HF antenna: 28.22 V @    13.56 MHz          

Some quick tests of the maximal distance between antenna and tag, with LF antenna mounted on the PCB:

  • LF HID read: 1cm

  • LF EM4100 read: 3cm

  • LF Hitag2 read: 3.5cm

  • HF MFC read: 7cm!!!

Without the LF antenna:

  • HF MFC read: 8cm!!!

It's fully compatible with official firmwares, comes with 2.0.0 and works nice with 2.2.0 and with today git HEAD as well.

BTW it came from http://www.aliexpress.com/item/2016-lat … 17468.html

UPDATE:

There is one limitation, thanks moebius for having spotted it.
It's an AT91SAM7S256, not AT91SAM7S512 so twice less memory (note in the capture below I already flashed the fw):

How did you flash it? I tried to upload it to 2.4 firmware version and now Im having problems recognising the device.
