From: Alexey Kosmakov <a.kosma...@nag.ru>
SNR SNR-CPE-ME2-Lite is a 2.4/5 GHz band 11ac (Wi-Fi 5) router, based on
MT7621A.
Specification:
- SoC : MediaTek MT7621A
- RAM : DDR3 128 MiB
- Flash : SPI-NOR 16 MiB
- WLAN : 2.4 GHz 2T2R (MediaTek MT7603E)
5 GHz 2T2R (MediaTek MT7613BE)
- Ethernet : 10/100/1000 Mbps x5
- Switch : MediaTek MT7530 (SoC)
- UART : through-hole on PCB
- J4: 3.3V, GND, TX, RX
- 57600n8
- Power : 12 VDC, 1.5 A
Flash instruction:
1. Boot SNR-CPE-ME2-Lite to recovery mode (hold the reset button while
power on)
2. Send firmware via TFTP client:
TFTP Server address: 192.168.1.1
TFTP Client address: 192.168.1.131
3. Wait ~120 seconds to complete flashing
