In case you you still think OpenWRT capable NEXX WT1520 router is still too expensive at $15, what about an $8 OpenWRT router? That’s what LY mini wireless router costs including shipping, and it’s better known as A5-V11, the name of its PCB.
- SoC – Mediatek/Ralink) RT5350F MIPS processor @ 360MHz
- System Memory – 32MB RAM (W9825G6EH-75). Some people reported theirs only have 16MB RAM, so YMMV.
- Storage – 4MB NAND flash (Pm25LQ032)
- Connectivity – Wi-Fi 802.11b/g/n up to 150 Mbps; 1x 10/100M Ethernet
- USB – 1x USB 2.0 host port, 1x micro USB port for power
- Misc – Power LED, factory reset pinhole
- Power – 5V via micro USB port
- Dimensions – 6.1 x 2.3 x 1.4 cm
Contrary to WT1520, A5-V11 is already part of OpenWRT trunk, but the firmware image is not automatically built yet. Fully details can be found on OpenWRT Wiki. If you connect a serial board, you may have to add a 470 Ohm to 1 KOhm resistor to the Rx pin to prevent the board from hanging at boot time.
The router can be purchased on Aliexpress for $8.25 including shipping, DealExtreme for $10.86 (with 32MB RAM), or Ebay for $8.72. It might be on other websites too, but since it’s an OEM product without clear branding it may be difficult to find.
Thanks to Maurer for the tip.
