 ### Board Connectors
 
-<p style="text-align: justify;">The Nano 33 BLE Sense Rev2 exposes two 15-pin headers that can be assembled with pin headers (SKU: ABX00070) or soldered directly via castellated vias (SKU: ABX00069). The headers follow the classic Arduino Nano pinout for compatibility with existing shields and accessories.</p>
