ChameleonUltra
Hardware
The Chameleon comes in 3 Hardware variants, the Ultra, the Lite and the Devkit.
The Ultra
The Chameleon Ultra comes in a black box with gold printing. This box has the following dimensions: 9.5 cm x 5.5 cm x 3.5 cm
The Box contains a foam pad, a USB cable that has a removable end to convert it to USB-C, a Proxgrind 3.5 hex screwdriver, 2 replacement screws and a keychain and the device itself.
The device itself features 4 screws holding it together, 2 buttons labeled A and B. The device consists of 2 PCBs (Printed Circuit Boards) and a plastic spacer, one contains the Electronic and the HF (High Frequency), 13.56 MHz, antenna as well as the 8 LEDs indicating which slot is currently active and the other board features the Chameleon Ultra text, the screws and the LF (Low Frequency), 125KHz, antenna. The plastic spacer houses the battery as well as the ferrite pad which enables HF and LF emulation at the same time. It also has has the USB-C charging and data port and a hole for inserting the keychain loop. The Chameleon Ultra dimensions are: 2.4cm x 4cm x 8mm
The Lite
The Chameleon Lite comes in a white box with blue printing. This box has the following dimensions: 9.5 cm x 6 cm x 3.5 cm
The Box contains a foam pad, a USB cable that has a removable end to convert it to USB-C and the device itself.
The device itself features 2 buttons labeled with arrows. The device consists of one PCB in a blue plastic housing. This one PCB contains the electronics and the HF antenna as well as the 8 LEDs indicating which slot is currently active, and the USB-C port. The LF antenna is glued onto the back of the PCB and is visible through the housing. The battery is soldered in place and the housing is held together by thin fragile pins which are easy to snap. It is not designed to be disassembled. The keychain loop is also relatively fragile, so be careful. The Chameleon Lites dimensions are: 3.6 cm x 6.1 cm x 0.8 cm
The Devkit
Just like the Chameleon Ultra, the Devkit comes in a black box with gold printing. This box has the following dimensions: 12 cm x 8 cm x 3.5 cm
Again, just like the lite, the box contains a foam pad, a USB cable that has a removable end to convert it to USB-C and the device itself.
The device itself features 2 buttons labeled A and B. The device is made of only one PCB without a case. At the bottom of this PCB both the HF and LF coils are found. Because it is a Devkit, this Chameleon has its SWD (Single Wire Debug) port and some testpoints exposed. (In the photos below, a pinheader is already soldered into the SWD port, this is not the case from factory) The Chameleon Devkit dimensions are: 5.3 cm x 8.5 cm x 1.1 cm (including rubber feet, battery and buttons. PCB thickness: 0,16 cm)
What is the difference between the Lite and the Ultra/DevKit?
The Chameleon Ultra as well as the Devkit contain a second chip called MFRC522 . This chip allows the Chameleon to read and write to HF 14a tags. The Chameleon Lite does not contain this chip and therefore cannot read and write HF tags, it can only simulate some. The Chameleon Lite also swaps the big LIPO (LIthium POlymer) battery with a smaller buttoncell. The Devkit is a Chameleon Ultra on a bigger PCB and with a bigger battery and some component differences such as a mechanical relay but which should not make any practical difference.
