Description: VS1063 is an easy-to-use, versatile encoder, decoder and codec for a multitude of audio formats. With this breakout board, it’s easy to drop it into any project. The VS1063 is capable of decoding Ogg Vorbis/MP3/AAC/WMA audio and encoding MP3, IMA ADPCM and user-loadable Ogg Vorbis. This breakout can also drive 30 ohm headphones with no additional power supply..


  • Separate Audio and Digital 3.3V supplies
  • Onboard 12.288MHz oscillator


  • 1.5 x 1.75" (38 x 44.5mm)

Customer Comments

  • Can I simply connect this and use it without any programming etc? i.e. is there a hardware mode etc?

  • How many layers does this board have? 4?

    • Nah, it’s just a 2-layer board.

      • I’m trying to understand how is the ground pin connected (in the eagle files)… to me it looks unconnected, but I’m new to this stuff… is it really so?

        • Usually a ground plane. By default Eagle doesn’t always show you the ground plane, but basically anywhere that doesn’t have a trace is just a big copper plane that is usually used for ground. This is the case on both sides of the board. So it may just look like a small wire to nowhere, but its going to the ground plane.

  • Anyone tried reprogramming the VS1063 directly? I’m wondering if I can download the VLSI VSIDE and reprogram the VS1063 on this board.

  • what voltage is needed at VCC? ive heard 3.3v and 5v and really dont want to blow up the chip!

    • Good question! The max of VCC is set by the max of the on-board regulators, which’d be about 6V (the max of the SP6214 2.8 and 1.8V regulators). The minimum of VCC would be about 3.3V.

  • I have a question about the patch. Are patch permanent? In other word does the patch modify the ROM or do I need to provide the patch each time I power it on? From what I understand from is that I need to keep the patch stored on the SD. And each time the system is powered up the patch is applied but not stored in the VS1063 ROM. If so, is there a way to store the patch on arduino instead of the SD? Thank you

    • It’s my understanding (subject to being wrong) that no, patches are not permanent, which is why you load them after every powerup. If you have the space (there’s only 32K total), there’s no good reason why you couldn’t store it in the Arduino’s flash and load it from there. Also note that if you don’t need the specific features of a patch, we’ve had good luck with the bare ROMs (in other words, we usually don’t need the patches).

      EDIT: more authoritative answer: no the patches are not permanent and if you wish to use them they must be loaded on each powerup of the VS1053.

      • And if anyone, like me, is wondering how to load it from flash:

  • There’s only one LINE input! Could anyone explain to me how to use the stereo line input? In the ds it looks like the MICP is used as Line 1. Should I use MICP as Line 1, and LINE as Line 2? Thanks

    • Please read more of the datasheet. You can use MICP and MICN as a single differential input, or set up the registers to use it as left and right inputs.

  • Please identify a compatible microphone and add it to the related products section.

    I ordered the MEMS mic BOB. Can/should I connect GBUFF to MICN to match the VCC/2 floating output of the MEMS mic? The datasheet specs the MIC pins as “self-biasing”… ??

    The MEMS puts out 200mV p-p but the datasheet indicates 140mV p-p as a maximum to avoid distortion. Will the MEMS mic damage this module? If not, will the sound quality be ok?


  • Can this board play more than one sound file at a time? If not, can someone recommend a board that can?

Has any one successfully gotten this board to work. ?

I bought 2 of these boards and for weeks I still can’t get this board to respond to a simple spi command.

I thought the first board was bad so i got another one and this new one still doesn’t work.

I order this board along with the second order and this one works at first go. No issues.

I started researching this and there is some confusion with vlsi solution saying some of these board has wire missing that needs to be pull up to vdd. I’m disappointed with this product because i ask sparkfun to test this board before they send it to me and clearly they didn’t test it.

If there is a known issue with this board then why are they still selling it on the website. Why hasn’t it been removed.

I’m sorry, but we do not offer hand testing of products for customer purchases. It’s simply not an option we can support. Though those boards are hand tested before being released from our production process. Each unit is checked to ensure it plays a proper test sample out of a speaker. To have 2 units over 2 orders that are both not working is strange. Please contact our support team. They’ll be happy to help you trouble shoot. We will likely need to pull both boards back for inspection and testing. If there is a manufacture defect found, we’ll certainly help you with that.
