Maximum Current Output per Port¶
To ensure stable operation when powering external devices directly from the board's USB ports, headers, and M.2 slots, do not exceed the following current limits.
Note
All values listed below represent continuous (sustained) current limits.
-
5V Output (USB Ports & Headers)
Port / Header Max Output Current Notes Front USB Type-A (2 ports) 2.1 A Shared between both ports Rear USB Type-A (2 ports) 2.1 A Shared between both ports USB 2.0 Header 2.1 A — Front USB Type-C 3.0 A — Rear USB Type-C 3.0 A — Total 5V Current Limit: The combined current draw across all above 5V outputs must not exceed 8 A.
-
3.3V Output (M.2 Slots)
Slot Max Output Current Notes M.2 M-Key (3 slots) 6.0 A Up to 6.0 A per slot M.2 E-Key (1 slot) 2.0 A — Total 3.3V Current Limit: The combined current draw across all four M.2 slots must not exceed 8 A.
