Printed Circuit Board Assemblies
The first 10 Firefly Ice prototype printed circuit board assemblies (PCBA) have been ordered. All the components have arrived and the printed circuit boards are currently being fabricated. The complete PCBAs are scheduled to arrive in early April. The hardware will then be tested for functional correctness and expected power consumption. If revision is required, another prototype build will be started at the end of April.
A very simple 3D printed enclosure will be used to protect the PCBA while developing the device and testing it out in real world scenarios. This enclosure will be very easy to take apart for reprogramming the PCBA via the ARM SWD pads. These will be very inexpensive to produce in small quantities via 3D printing services such as Shapeways.
Once the hardware is checked out, the development focus will shift to the firmware, data uploading app, and cloud storage.
