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
