### J8 — XBEE-ROW-2

Fila 2 del zócalo XBee: **pad k = pin XBee (21 − k)** (espejo; regla verificada en el Informe técnico V3+V4 contra el footprint-R00 de ArduSimple: J8.8 = pin 13 LED, J8.6 = pin 15 GND, J8.10 = pin 11 GND). La net `XBEE_ONSLP` en J8.3 (R109 **DNP**) corresponde por esa regla al pin XBee 18; el ECO la etiqueta «pin 13 ON/SLEEP». <!-- VERIFICAR contra el datasheet del 4G NTRIP Master antes de poblar R109 -->
