For the Pika Flight Management Unit.
Bill of Materials
The following are needed to assemble one Pika Flight Management Unit. The minimum PCB purchase from OSH Park will be for three circuit boards; however, the rest of the components are for a single Pika:
- Pika PCB from OSH Park
- Shared cart of components from Digi-Key
- One TSR 1-2450 from Mouser
- One Teensy 3.2 from Osh Park
- One MPU-9250 breakout from Embedded Masters
The total cost is approximately $92 for one Pika FMU or $215 for three.
Known Issues
- 5V supplied to MPU-9250 instead of the recommended 3.3V. Does not appear to affect operation.
- The silkscreen for GPS, TELEM, and the BFS Bus are partially obscured by the connectors
- The mounting hole diameter is 0.3 mm diameter oversize for an M3 standoff. The mounts will still work; however, because the BeagleBone Black headers set the board alignment and the hole center locations are correct.
