The ZyXEL LTE3301-Plus is an 4G indoor CPE with 2 external LTE antennas.
Specifications:
- SoC: MediaTek MT7621AT
- RAM: 256 MB
- Flash: 128 MB MB NAND (MX30LF1G18AC)
- WiFi: MediaTek MT7615E
- Switch: 4 LAN ports (Gigabit)
- LTE: Quectel EG506 connected by USB3 to SoC
- SIM: 1 micro-SIM slot
- USB: USB3 port
- Buttons: Reset, WPS
- LEDs: Multicolour power, internet, LTE, signal, Wifi, USB
- Power: 12V, 1.5A
The device is built as an indoor ethernet to LTE bridge or router with Wifi.
UART Serial:
57600N1
Located on populated 5 pin header J5:
[o] GND
[ ] key - no pin
[o] 3.3V Vcc
[o] RX
[o] TX
For more details about flashing and bootloader see commit
2449a632084b29632605e5a79ce5d73028eb15dd .
Installation:
1. Upload image via web interface or via bootloader.
2. Wait for the device to come up.
