手順20
We lay out the controller boards in search of more silicon. Here's the feature-rich red board in all its glory (the blue board is shaped a bit differently, but has most of the same bits): Broadcom BCM20734 Bluetooth 4.1/2.4 GHz Transceiver
  • We lay out the controller boards in search of more silicon. Here's the feature-rich red board in all its glory (the blue board is shaped a bit differently, but has most of the same bits):

  • Broadcom BCM20734 Bluetooth 4.1/2.4 GHz Transceiver

  • STMicroelectronics ST21NFCB NFC controller

  • Macronix International MX25U4033E 4 Mb CMOS Flash

  • STMicroelectronics STM32P411 32-bit microcontroller

  • STMicroelectronics LSM6DS3H 3-axis accelerometer/gyroscope (likely)

  • Texas Instruments BQ24072 linear battery charger w/ power path management

  • Rohm BD27400GUL mono class-D audio amplifier

Stacchiamo le schede del controller cercando altro silicio. Ecco la scheda rossa in tutta la sua gloria (la scheda blu ha una forma un po' diversa, ma condivide la maggior parte degli elementi):

Ricetrasmettitore Bluetooth 4.1/2.4 GHz Broadcom BCM20734

STMicroelectronics NFCBEA 812006 33 (Probabilmente un lettore NFC reader)

Memoria Flash CMOS da 4MB Macronix International MX25U4033E
