BoatGPS – PCB

Using Eagle, a great schematic and PCB layout program, I had a go at creating a PCB for building the BoatGPS that I prototyped earlier using some Veroboard.

Here’s some photos of my first PCB attempt:

After some soldering, here is the board populated – and connected to an EM406A GPS receiver:

As can be seen, some mistakes were made on the PCB layout – namely some power connections….

Wires to fix the routing mistakes!

Here is the PCB version installed in to a die-cast aluminum enclosure undergoing some drive tests in the car.

I assembled a second board in anticipation of being used as a tachometer for the boat. Here it is displaying the speed in kM/h, with the LED backlights on, in the car.

Time to clean up the software a bit, and decide if a re-spin of the PCB is warranted!
