Overview

"ESR900-0.20 LFP" is silkscreened on the board in the FCC photos.

The Flash chip appears to be a Macronix MX25L12845EMI-10G.

The 2.4GHz radio is using three SST (Microchip) SST12LP154 PA ICs.

The default SSID pattern (for both bands?) may be EnGeniusXXXXXX.

The power adapter shown in the FCC external photos is a Shenzhen Gongjin Electronics (SGE)

S24B12-120A150-04 (100-240VAC ~ 50/60Hz, 0.7A max. -> 12VDC, 1.5A).
