  • The board in the top left provides the power. The board on the right carries the juicy stuff:

  • Bluetooth Module featuring the CSRA64110 Mono Audio Module with its antenna running along the top edge of the PCB.

  • The chip found in this video from "This Does Not Compute" in the 2018 model was a CSR64215 and in theory capable of aptX and stereo output—seems IKEA switched to the CSRA64110 in later models.

  • STM32F030 microcontroller featuring an Arm® Cortex®-M0

  • TAS5731M Stereo Digital Audio Power Amplifier from Texas Instruments

  • PCM1808 Stereo A/D Converter from Texas Instruments

  • Consonance Electronic CN3704 Standalone Li-ion Battery Charger
