The product has Micro-USB and USB-C connections. Its published hardware architecture consists of the LF antenna board, middle extension board, and Proxmark3 base board.
Radio and Firmware Compatibility
The documented LF hardware targets 125 kHz operation; do not assume 134 kHz support from the upstream client's protocol list. HF operates at 13.56 MHz with supported protocol commands determined by the firmware and client.
Factory firmware packages and current custom builds have different version requirements. For custom RRG builds, Proxmark3 X uses PM3GENERIC with BTADDON; its factory description as RDV4-compatible does not mean the RDV4 build target is correct for a new custom build.
Start with Connection and Platform Setup, then inspect hw version before selecting update files.
