SAAndcard

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.

Today (20170926) the boards and crystal oscillators arrived! The boards look very nice. Later on I will populate and test them.

Populated and tested (20171001), and after some minor adjustments, it is alive! :D Some kits will be reached out to the test panel soon. :)
