Great news, the prototype boards arrived in the mail yesterday for TinyTimer-Kickstarter edition. I’m hoping to work on assembly and testing this week. I’ve been doing some construction on my house and my office is a bit of a mess. I did a quick test fit of the LED module and Max7219CNG chip and both fit great. There is always a risk when using a new part that the footprint will not match the part. I try to avoid that by printing the board layout on paper and laying the part over it. That helps spot major issues, but it’s not fool proof.
