Soundcard (kit) for Arduino/Wemos boards based on a SAA1099 stereo soundchip.

Compatible with:

  • Arduino Uno R3
  • Arduino Nano R3
  • Wemos D1 R2


Specs:

  • Stereo sound through SAA1099 chip
  • Mono sound out of PWM pin of uC
  • MIDI input, routed to RX or a standard I/O pin (use header for selecting which one)
  • TTL serial on 3 pin header (MIDI can use RX)
  • 3,5mm jack output
  • SPI is used for sending the data to the soundchip via a 74HCT595
  • The output, clock and latch of the shift register are available on a pin header.


More after I have received, populated and tested the PCBs.
