+
+## Brands
+|Brand|Type|Managed|PCB|Flash|Chip RTL|
+|---|---|---|---|---|---|
+| Lianguo | ZX-SWTGW215AS | Yes | PCB-SWTG115AS-V2.0-16030 | 2MB (FM25Q16A) | RTL8372 family |
+
+## Overview
+
+This device is a managed 5-port plus 1 SFP switch supported by RTLPlayground.
+
+- 5 x RJ45 ports
+- 1 x SFP port
+- Managed web firmware
+- Original SPI flash chip: FM25Q16A
+
+## RTLPlayground target
+
+Use machine target `MACHINE_LIANGUO_ZX_SWTGW215AS` for this device.
+
+## Notes
+
+- The original unit was fitted with an `FM25Q16A` flash chip.
+- In the current codebase, this device is treated as a 5+1 managed variant in the RTL8372 family.
+- There is a second SOIC8/SOP8 footprint (label U10) beside the flash chip. Likely
+- Uart follows standard pinout scheme for these units. 
+- T8 Connector seems to be a JTAG port for main CPU
+- T3 connector is wired to second(unpopulated) SPI flash footprint
