Senaos line of Ralink based routers are sold as Engenius/Senao but are also rebranded (ODM and OEM) for a whole bunch of other vendors.
 * Hardware:
 * Looking at Senaos circuit boards one can see that they are of high quality build and Senao has created
 * a smart layout where they can use an RT3050 or a RT3052 SoC on the same type of circuit board.


 * Software:
 * The header of the stock firmware tells us in the first 16 bytes which Senao basic model a router is based on:

00 00 00 00 00 00 02 05 00 00 00 05 31 32 33 00

byte 11 is the board identifier:
 * 01 = ESR-9750 (802.11n Router, Platform: RaLink 2880 SoC + 2860)
 * 02 = ESR-9750A (802.11n Router, Platform: RaLink 2880 SoC + 2860 + RTL8366SR GbE)
 * 03 = ESR-9750G (9750A with 32MB RAM)
 * 04 = ECB-9500
 * 05 = ESR-9750B (9750 with 32MB RAM)
 * 06 = EOR-7550 (Dual-radio)
 * 07 = ESR-9752 (3052, 16MB RAM, 4MB Flash)
 * 08 = ESR-9753 (3050, 16MB RAM, 4MB Flash)
 * 09 = ESR-7750
 * 0A = ESR-7850 (Atheros 11n AP94/96 platform)
 * 0B = EAP-3670
 * 0C = ESR-9752A
 * 0D = ESR-6650 (3G Router - 3050)
 * 0E = ESR-6670 (3G Router - 3052)
 * 0F = ESR-6670A (3G Router - 3050)
 * 11 = ESR-9850 (3052, 32MB RAM, 4MB Flash, RTL8366RB GbE)
 * 14 = EAP-9550

 * 21 = ETR-9330
 * 22 = ETR-9360
 * 23 = ESR-1221N2


 * P/Ns starting with 7016A are frequently on their boards.
 * Typical Senao format labels may affixed to them.


 * "P/N: 5816Axxxxxxx" are printed on the stickers on the module.

Examples

 * No Geek Needed NGNHWI-N3
 * "7016A0251010" is silkscreened on the board.
 * "P/N: 5816A0251010" are printed on the stickers.
