Zyxel GS1900-24EP
The GS1900-24EP is a 24-port Gigabit L2 switch with up to 130 Watts of PoE power on the 12 Gigabit ports
Hardware
- Nuvoton NUC029ZAN ARM microcontroller
- 2x 8-port PHY extenders
- 2x RTL8231 GPIO extender to control the port LEDs
- Winbond W631GG8NB (128MB DDR3 SDRAM)
- Winbond W25Q128JVSQ (16MB flash)
Power is supplied via a 100-240V C13 connector.
PoE is controlled by 2 Realtek RTL8238 PSE controllers via the Nuvoton NUC029ZAN ARM microcontroller.
Pinouts
Header JP1 has a UART:
- JP1.1: 3.3V
