Tell us about yourself!
Seems like there are some power issues for folks. Generally speaking - it is not advised to power devices from two sources! If you use the 9V battery... do NOT connect the VCC from the CH340 to the mini - ONLY connect GND and the TX/RX pins.Stuff like this is always better powered from a single supply as well (though it's not necessarily needed). I too am powering things off of a 9V battery when not connected to a computer... but when I connect to the computer to change the code I remove the 9V battery and get power from the computer.
Simply disconnecting the buzzer should not damage anything (I've disconnected the pin a lot myself). Shorting the removed pin to another pin on the board could potentially damage the board.
The sdcard.org file keeps telling me to remove the write protection on the card. Of course, microsd doesn't have a write protection switchThe LLF is the first software package that has told me that it's successfully formated on of my chips... so that's improvement. When I put the image on the card (using Win32DiskImager) it just sits there - nothing - not even an LED. I'll try a couple more times.
I'm a little late to the party but - There's not a .raw file... it's now a .img file based on 5.20 release. I can't get it to boot still :/ I tried making the drive a boot drive, I also changed it to a .raw extention. I had some moderate success with 5.14 release (it was a .raw file), but It would fill up my 8G drive that I have. The 16G SDcard that it came with wouldn't work, and they sent me a replacement that also didn't work.Any hints would be appreciated.
