The TapNLink Wi-Fi, BLE, NFC module is equipped with an ESP32 microcontroller that
executes:
1. The main program
2. Manages the upper level protocols
3. Manages the configuration and access control
4. Manages the Wi-Fi or BLE stack and acts as a simple transmitter.
The circuitry for both the NFC and the Wi-Fi/BLE antennas are outside of the shielding case.
The NFC antenna is a trace at the periphery of the printed circuit board. The 2.45 GHz antenna
is a ceramic device located close to the L slot in the printed circuit board.
