RfidResearchGroup/ChameleonUltra
FreeThe new generation chameleon based on NRF52840 makes the performance of card emulation more stable. And gave the chameleon the ability to read, write, and decrypt cards.
About RfidResearchGroup/ChameleonUltra
ChameleonUltra is an open-source hardware and software project by RfidResearchGroup for a next-generation RFID/NFC multi-tool. Based on the NRF52840 microcontroller, it offers improved stability in card emulation and adds capabilities to read, write, and decrypt various card types. The project includes firmware, hardware designs, and compatible applications such as ChameleonUltraGUI, MTools BLE, and a dedicated iOS app. It supports protocols including Mifare, NTAG, ISO14443A, 125 kHz, and Ultralight, making it suitable for security research, card cloning, and RFID testing. The community is active on dedicated Discord channels, and the source code is licensed under GPL-3.0.
