A flexible printed circuit (FPC) breakout board is required. It should have:
- 24 pins with 0.1" (2.54mm) pitch
- One side with 0.5mm pitch FPC connector (for lemp9)
- One side with 0.5mm pitch FPC connector (for the Lemur Pro)
- One side with 1.0mm pitch FPC connector (for all other models)
Depending on the vendor, the connectors may not come soldered to the board (or
