Pansenti on SEN-11486 - 9 Degrees of Freedom - MPU-9150 Breakout
We’ve tried to make it as easy as possible to use the MPU-9150 on the Arduino (and now the Raspberry Pi too). The user sketch just needs two function calls – init() and read(). It’s as simple as that!

Can someone explain what the signal pulse would be for the two coin types? I’d like to use this with an Arduino and am not sure what to detect.

Some things need to be mentioned about this thing. The datasheet is dead wrong about current draw. It says 65mA. In reality, I am reading about 160mA nominal, and when you put a coin in it spikes to...

Hi guys, despite of the traces for output being wide looks like the connection between the MOSFET and the GND traces are really small ones. Looking at the pictures It seems to be a very weak point of...

You can, but you need to be really careful if you decide to charge them when connected together. They need to be balanced to prevent any issues or damage to the cells occurring.

This might seem extremely basic, but what kind of connector is the 8 pin one that’s included with the board? Can’t seem to locate the female connector that goes into it.

In the text above, you say “The shield uses SPI to communicate with the WM8731 so it won’t work directly with the Arduino Mega…” Could you explain? The Mega can do SPI.

Great code you have so far. One thing I haven’t figured out yet is how are you handling the start-of-message interrupt, and EOM interrupt, and further, auto muting the audio in between alerts and...

Correct me if I am wrong, but those large pads are there for attaching conductive thread, not for extremely high current outputs. You are still limited by the size of the pins on the IC, and the traces...

Current capacity is a volume thing. The pins on the IC typically have much more volume (height? depth? not sure what the right geometrical term is) than a copper trace on a PCB board will. For high...
