Description

H07R3x is an audio amplifier and speaker module based on ST TS4990 1.2W audio amplifier and STM32F0 MCU. This module features an on-board 8-ohm rectangular CUI speaker and a headphone output jack. Use this module to play sounds and tunes stored in the MCU embedded Flash or streamed from an external hardware/another module via array ports.

Specifications

Hardware Release Notes

H07R30

  • Initial hardware release.

H07R31

  • Added a DC-blocking capacitor (C12) to reduce amplifier heat-up.
  • Added input low pass filter footprint (DNP).
  • Updated amplifier feedback resistor and capacitor values.
  • Changed the MCU to STM32F091CCU6 to increase Flash size to 256Kb.
