Description
- This module is built around NXP PN532, and the maker break out almost all of the I/O pins of the NXP532 chip on this little module.
- In the module, the I2C and HSU share the same pins. The definition of the I2C pins is labeled on top of the breakout board, while the HSU’s is labeled at the bottom. Although the HSU mode is configured as the default mode, with a small on-board SMD DIP switch, it becomes pretty easy to change among I2C, SPI, and HSU interfaces.
- 80C51 microcontroller core with 40 Kbyte ROM and 1 Kbyte RAM
- Highly integrated analog circuitry to demodulate and decode responses
- Buffered output drivers to connect an antenna with minimum number of external components
- Integrated RF level detector
- Integrated data mode detector
