Here’s a photo of the boards I showed a short while ago in an assembled state. The transmitter seems to be working great, and I haven’t found any errors on this board revision.<\/p>\n

The wires you see at the top of the photo are the power and signal wires from a GPS module, and the wires you see at the right are from a lithium battery being used to power the board.<\/p>\n

Speaking of powering the board from a lithium battery, this board revision includes a boost regulator which takes the voltage from a lithium battery and boosts it to 5V for the system to use. I ran a test using a single battery and let the system run. It managed almost 19 hours! There’s a lot I could do to try and extend that number, but it’s a great number for having done relatively little to improve efficiency.<\/p>\n
