【Bargain Find】Electronic Music Box Circuit Board with S1V75701C06G1
44.88 $
Description
This is a compact melody board equipped with the S1V75701C06G1, known for its use in Tobu Railway signal opening melodies and more.
This is a prototype version of a custom board I made quite some time ago, so the craftsmanship is rough, but the back is fully soldered for durability.
Despite its small size, it packs high performance for a melody music box board, including a speaker drive circuit with a power amplifier IC, a constant voltage circuit controlled by transistors, a volume control knob, and DIP switches for song selection and melody start/stop, all on a single small board.
This allows for external devices to be limited to just a power supply (DC 8V-14V) and a speaker (2.5Ω-9.6Ω).
A simple instruction manual detailing how to connect the speaker and power supply will be included.
The board has been confirmed to be in working order, but as it is a personal creation, no quality guarantee is provided.
Also, due to the nature of producing multiple units, the manufacturing numbers of the melody IC and other electronic components may not match those in the images.
Thank you for your understanding.
It will be shipped via Rakuraku Mercari Bin.
