## RTLPlayground target
|
||
|
||
Use machine target `MACHINE_LIANGUO_ZX_SWTGW215AS` for this device.
|
||
|
||
Physical hardware verification: 5x RJ45 ports + 1x SFP port.
|
||
Port 5 RJ45 is interfaced through a RTL8221B IC.

### Notes
|
||
* Not all signals were mapped mechanically, hence they've been left out of documentation.
|
||
|
||
## T3, Slave Interface
|
||
|
||
This connector goes to U4 `I2C EEPROM` and U10 `SPI FLASH` (mappings identical to SWTG024AS).
|
||
|
||
For detailed Slave Interface functionality and protocol information, see [T3 documentation in SWTG024AS.md](SWTG024AS.md#t3-slave-interface).

||
|
||
|`T3` pin|what|Signal|

|---|---|---|
|
||
|1| U4-P6, 33R U10-P6 | I2C-SCL, SPI-CLK, Slave SCK/SCL/MDC/EE_SCL |
|
||
|2| GND | --- |
|
||
|3| U4-P5, U10-P5 | I2C-SDA, SPI-DI/DO, Slave SDI/SDA/MDIO/EE_SDA |

|
||
|5| 33R -> U10-P2 | SPI-DO/D1 |
|
||
|6| U10-P1 | SPI-CS |
|
||
### Notes
|
||
* 1 pin is square shaped.

## Notes
|
||
|
||
While [SWTG024AS.md](SWTG024AS.md) can be used as a general reference for hardware concepts and interface specifications, this device should not be assumed to be identical beside the difference implicitely highlighted below. Not all information has been validated for compatibility with the SWTG215AS. Consult the SWTG024AS documentation with caution and verify any critical details against this device's.
