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.
