Usage
The package list of Radxa 25W PoE+ HAT for X4 is as follows:
- Radxa 25W PoE+ HAT for X4
- 4x M2.5x9+6 Copper Pillars
- 4x M2.5x4+6 Copper Pillars
- 4x M2.5x5 Copper Pillars
If you want to use it together with Radxa Heatsink for X4, then you only need to replace the M2.5x9 + 6 copper pillar with the M2.5x9 + 3 copper pillar.
Installation Steps
-
Pass four M2.5x9+6 Copper Pillars or M2.5x9+3 Copper Pillars (if using heatsink) through the four positioning holes of the SBC, and secure them from the bottom.
-
Align the Radxa 25W PoE+ HAT for X4 with the PoE interface and the 40-Pin interface, ensuring the 12V power interface is aligned, and insert it carefully, ensuring that it passes through the four Copper Pillars.
-
On top of the Radxa 25W PoE+ HAT for X4, use M2.5x4+6 Copper Pillars or M2.5x5 Copper Pillars to secure it in place.
-
Connect an Ethernet cable to the PoE interface, ensuring the other end is connected to a PoE+ compatible switch.
