Arduino controlled Dual Mono AK4490 DAC (part 2)

STM32_MB_1-Small

An update on Arduino controlled Dual Mono AK4490 DAC project we covered previously:

After I was certain that everything related to the software was working the way it should, I designed a “motherboard” that would take care of the following:

  • Accept the STM32F106 board
  • Accept the 3.5″ TFT
  • Accommodate an 24LC256 EEPROM chip, used to store the DAC’s configurable settings
  • Accommodate two sets of I2C signal isolators and I/O expanders
  • Include headers for the encoder, IR receiver, power relay, non-isolated and isolated I2C communication, unused uC pins, etc
