I have designed a new flightcomputer. It’s modular. It measures about 4cmx4cm (tiny!) consists of 4 parts:
- Arduino Pro Mini
- Custom Battery PCB (3xAAA) with batteryholders, SD slot & LED
- Custom GPS (Lassen IQ) Breakout PCB
- Custom Radiometrix (5v and 3v3 selectable!) Breakout PCB
And now, please take some time to review the carefully organized schematics. Try doing that without blinking.
