Customer Comments

  • Can I control this directly from a TTL serial port like the Arduino’s or do I need some sort of RS232 converter?

  • Can this device be used for recording audio? The application I have in mind is recording off a radio channel (on CD) continuously to SD card. This is whats commonly called a “voice recorder” application.

  • It appears from the photo that the JTAG connector is a smaller pitch 2x5 pin header. Anyone know if there’s an adaptor cable for the Olimex OCD USB debugger/programmer?

    • On another subject I note you designed the “MP3 Trigger”. Would it be possible to get a fimware version that has a “PTT” output on one of the I/O lines corresponding to TRIG17 or TRIG18? A “CD” input to hold off for a clear radio channel would also be useful. I also found experimentally that the MP3 trigger thinks tracks are approx 1.4 sec longer than they actually are [time from start of play to “X” response].

  • hmmm…. why did they NOT provide a breakout for what is probably the BEST feature on the whole device (I2S) and not breakout for the additional STM32 pins? This would have been perfect to make a small, high end music server with its own filtering of the DAC….. Guess I am stuck with like 3 extra boards that cost as much as this does!

  • PCB: FR-4, 1.5 mm (0,062"), green soldermask, white silkscreen component print
    Slightly contradictory to the picture…
    On another note, this is a very nice looking board, this would be a great way to get into working with the VLSI chips and even ARM development. And it’s incredibly cheap!

  • awesome price =)
    edit: holy s*** REALLY awesome price man…
    bad thing about this is that I believe it does not have the bootloader which is cool because it wouldn’t be necessary to buy a JTAG programmer if you do not already have one.
    I believe the bootloader from stm32 is free, you guys could check it out, it’s really cool =)
    maybe on rev2 of this board =)
