Because of the coin cell there were special shipping instructions. It took a few extra days to reach me. Maybe
the board should be offered without that battery, or as an option. The 32khz crystal was a little fiddly to install,
but that’s a PJRC problem.

It was easy to assemble and makes the Teensy 3.2 into a very “Arduino-compatible” hardware package. I’m
very satisfied! Note: Because Teensy 3.2 is a 3 volt device, you must be cautious when using Arduino shields
with it. Take care to avoid accidentally connecting 3V and 5V to each other
Great expander!

Wonderful for prototyping. Note, however, that although it is pin compatible with Arduino Shields, the pinout
power will still be 3.3 volts. Some shields may not like this.

Attention to detail.
about a year ago by Member #116365 verified purchaser
I’m writing this review because they sent me an email requesting it. Although the overall design, electrically is
good, They need to pay more attention to the details. For instance, although electrically the Arduino footprint
is good, Only one of the mounting whole lines up with the Arduino footprint. And the one that does line up, is
pretty much unusable for that purpose because of the pin placement on the Arduino’s. And there’s not
anything that Spark fun can do about that one mounting hole. but the other two mounting holes are off by
about 2.5 mm between them. That is significant. also when using a standard proto-board, all pins, other than
the 10 pin Arduino connector, should be lined up on a .1 space grid. The additional pins that spark fun added
to the board, is not arranged on this grid. Whereas most are just barely off, the pin that contains the DAC pin
is .05 off. if you are using the spacer connectors to connect the Proto-board to the Teensy adapter board, the
pin spacing is not a problem. But if you are using a machined pin connector on the teensy to lower its profile,
or mounting the teensy adapter on top of the proto-board, this becomes a problem. The connectors do not line
up properly and has to be tilted to make the connection. This can stress the solder joints. On my application, I
need to deal with vibration. So I needed to primly connect these boards together via the mounting holes. I also
needed to minimize the profile that these boards take up. For these two reasons, this made the teensy adapter
board unusable for me. That is the reason I am only giving them three stars for this product.
I request that they please play more attention to the details.
Joe.
