I recently got a Ubiquiti EdgeRouter™ X SFP which has a really impressive feature set (quite close to “Enterprise routers” by Cisco or Juniper).
But what is under the hood of such a small device?
The processor is coverd by a heat sink glued to the package. I did not take this off, because I actually plan to still use the router for a while.
So I don’t know what is a the heart of the router, but the other components are identifiable:
- 256 Megabyte SLC-NAND by Spansion (2 Gb, x8, -40-85 °C industrial grade): S34ML02G200TFI000
- 256 Megabyte DDR3-RAM by Nanya (128Mb x 16, 1.35 V, 0-90 °C commercial grade): NT5CC128M16IP-DI
- Atheros RGMII/SGMII Transceiver (PHY): AR8033-AL1A
- a few Unisonic P-MOS transistors (probably for POE): UT4421G
- 2x Dual-Port 100/1000 Base-TX magnetics: Magtek G50206SNG
- 1x Single-Port magnetic: FPE LY24102SN (i could not find a datasheet or any specs for this component)
- MXIC 25L1608E -> probably an EEPROM?
- There are probably two switched power supplies on the board (at the two inductor coils), but I could not identify the model or brand of the controller ICs.
The back is rather unspectacular: a lot of discrete SMD components (mostly capacitors, resistors and transistors).
