The original A7672S 4G module footprint was removed from the design and replaced with a 4-pin external 4G header.
You should look for:
- Designator:
J_4G
- Type: 4-pin 2.54 mm vertical header
- Location: near the right edge of Zone 2
- Pins:
VCC_5V, GND_STAR, LTE_TX, LTE_RX
So there is no large 4G module on the PCB now — the board provides J_4G so you can connect an external 4G module by wires/header.
