The STM32F103C8T6 RFID module can read contactless smart cards conforming to ISO/IEC14443 TYPEA/B and ISO/IEC15693 (supports most cards on the market, shopping cards, student cards, bus cards, social security cards, resident health cards, bank cards, ID card, residence permit, etc.), easy to use and low cost, suitable for users of advanced applications such as equipment development and card reader development, and users who need to design/produce radio frequency card terminals. This module can be directly loaded into various card reader molds. The voltage of the module is 5V, and it can directly connect and communicate with any CPU motherboard of the user through the SPI interface with a few simple lines, which can ensure the stable and reliable operation of the module, and the card reading distance is 0-125px. Different types of cards are different. About STM32STM32F103C8T6 is a 32-bit microcontroller based on the ARM Cortex-M core STM32 series, with a program memory capacity of 64KB, a voltage of 2V~3.6V, and an operating temperature of -40°C~85°C.
