2x MOC3020 Optocoupler 400V

Reprogrammable voice module with large storage capacity that can support the maximum 1GB SD card, and support audio files of WAV and ad4 format.
Wtv020-sd module uses wtv020sd-20s Voice chip as master core, with MP3 control mode, one to one key control mode (control 3 voice groups or 5 voice groups), 2-wire serial port control mode and loop play mode after power on. Control mode is set by programming the voice chip, and can't change to another control mode during operation, what control mode do you need, just tell us, we can customize it for you.

Digispark is a development board based on the ATTINY85 microcontroller from ATMEL born in a successful campaign on Kickstarter.
Similar to the Arduino line , It is one of the smallest boards on the market.
Programmable directly from USB with the same Arduino tools. It has a built-in Micronucleus bootloader and can be replaced by similar ones such as the Trinket bootloader. Adafruit or others.
You can use many of the same Arduino libraries and you have your own on the digispark wiki. Arduino compatible Attiny85 Digispark board features:
- USB power supply
- External power supply (7v-35v DC 12v maximum recommended)
- 5V DC 500mA regulator on board
- Programmable with the Arduino IDE
- Loaded with Micronucleus bootloader
