# st25tb_kameleon ST25TB / SRx NFC Emulator / Initiator - kameleon - based on TI TRF7970A with MSP430 ## Description This is an **additionnal** support project of `ST25TB series NFC tags for fun in French public transports` [ST25TB_transport.pdf](https://raw.githubusercontent.com/gentilkiwi/st25tb_kiemul/main/ST25TB_transport.pdf) \- it is based on first [st25tb_kiemul](https://oshwlab.com/gentilkiwi/st25tb_kiemul) project. You can find presentation, documentation and firmware on GitHub: [https://github.com/gentilkiwi/st25tb_kameleon](https://github.com/gentilkiwi/st25tb_kameleon) )This is a new board based on MSP430FR2673 + TRF7970A, firmware (`st25tb_kameleon.hex`) ## Usage * Firmware must be loaded with a `MSP-FET` or `eZ-FET` emulator of another LaunchPad board. * Can be powered with +3.3V (on `VCC_TOOL`), USB (regulated on board) or a simple `LIR2032` battery (a battery holder must be soldered on the bottom side). * LIR2032 battery will be charged when USB is plugged ## Why `kameleon`? The name is more a tribute to original `Chameleon` device & research (@emsec), than because the device is a real `Chameleon`... :') ## Author Benjamin DELPY `gentilkiwi`, you can contact me on Twitter ( @gentilkiwi ) or by mail ( benjamin [at] gentilkiwi.com ) This is a personal development, please respect its philosophy and don't use it for bad things! ## Licence CC BY 4.0 licence - [https://creativecommons.org/licenses/by/4.0/](https://creativecommons.org/licenses/by/4.0/)
