Overview
Since it becomes harder and harder to source PN532 genuine chips in the market while the price is rising urgently, we decide to develop this PN7150 module. NXP released PN7150 to replace PN532. However, as PN532 becomes too popular, the market doesn’t want to update the chip. So NXP stopped producing more PN5321 and now the chip price is going crazy.
PN7150 is more powerful than PN5321. However, PN7150’s software could not be compatible with PN5321’s. To help PN5321 board users to switch to the PN7150 board, we made hardware-compatible design. PN7150’s board size, antenna size, and installing holes are the same with PN5321 board’s. If you switch to PN7150, you might only need to change the connection and your code. For new product developers, we recommend PN7150 because NXP could continue this chip while they might stop PN532 as PN532 is too old (almost 20 years).

Hardware information
This product has the same size and installation holes with PN532 NFC RFID MODULE V4. So it is easy to update with minimum changes.
