Proxmark3 X vs Proxmark3 RDV4.01

When it comes to advanced RFID and NFC tools, the Proxmark3 X and Proxmark3 RDV4.01 stand out as powerful devices. Both are designed for professional and enthusiast users who need to handle various RFID tasks, but they each have their distinct features and capabilities. This article aims to provide a detailed comparison between the Proxmark3 X and the Proxmark3 RDV4.01, covering aspects such as appearance, price, supported frequencies, extensions, connections, and firmware.

Appearance

The Proxmark3 X and RDV4.01 differ in design. The Proxmark3 X, based on the Proxmark3 Easy, has a more straightforward and potentially less refined appearance compared to the Proxmark3 RDV4.01. The latter boasts a more sophisticated design, which might appeal more to those who value aesthetics along with functionality.

Price

Model	Price	Notes
Proxmark3 X	$80	Suitable for beginer
Proxmark3 RDV4.01	$320	Suitable for professional

Budget is often a critical factor when making a purchase, and here, the Proxmark3 X offers a significant advantage over the RDV4.01. The Proxmark3 X is priced at $80, making it an attractive option for those on a tighter budget or for users who are new to the Proxmark3 series and wish to explore without a high initial investment. In contrast, the Proxmark3 RDV4.01 carries a price tag of $320, reflecting its more advanced features and higher-end design.

Supported Frequency

Frequency	Proxmark3 X	Proxmark3 RDV4.01
HF 13.56MHz	Supported	Supported
LF 125KHz	Supported	Supported
LF 134KHz	Not Supported	Supported

Both devices support HF (High Frequency) at 13.56MHz, which is common for RFID and NFC operations. However, they differ in their LF (Low Frequency) capabilities. The Proxmark3 X supports LF at 125KHz, which is suitable for basic RFID tasks. On the other hand, the Proxmark3 RDV4.01 adds an additional LF frequency support at 134KHz, making it more versatile for a broader range of applications where this specific frequency is required.

Extensions

The Proxmark3 RDV4.01 offers more extensibility options compared to the Proxmark3 X. It supports additional modules like a SIM card module and a Bluetooth module, which can significantly expand its functionalities and connectivity options. These extensions are not available on the Proxmark3 X, limiting its capabilities in comparison.

Connections

Connection	Proxmark3 X	Proxmark3 RDV4.01
Micro-USB	Yes	Yes
USB-C	Yes	No
Built-in Bluetooth SPP	Yes	Require Blueshark Adds-on

In terms of connectivity, the Proxmark3 X supports a more diverse set of ports, including Micro-USB, USB-C, and has built-in Bluetooth SPP. This makes it more versatile and potentially future-proof in terms of connectivity options. The Proxmark3 RDV4.01, however, only supports Micro-USB, which might be seen as less versatile, especially with the increasing prevalence of USB-C devices.

Firmware

Model	Firmware
Proxmark3 X	Proxmark3 Generic
Proxmark3 RDV4.01	Proxmark3 RDV4

The firmware for these devices also differs. The Proxmark3 X runs on generic Proxmark3 firmware, which is widely used and supported across different Proxmark3 models. This can be advantageous for finding community support and updates. The Proxmark3 RDV4.01 uses specific firmware tailored for RDV4 models, which might offer some unique features but could also limit its compatibility with universal Proxmark3 community resources.
