“Medion Life E1800” teardown

other brands

Based on a search of the “SB1024H” marking found on the pulse sensor’s connector tape, and then a visual comparison of the results, the following smartwatch brands & models might be the same device:

• “Medion Life E1800” (obviously - that’s the one I tore down)
• “iGET FIT F4” (mention)
• “Everis Neptune E4002” (mention)

The “SB” prefix may possibly be an abbreviation/acronym of “SmartBand”.

display

(Question on r/hardwarehacking)

The back side seems to show the following markings:

R096HQ1501A(L?)
180913 A2 P(O?)

pulse/heart rate sensor

The elastic tape seems to have the markings:

AB220-SB1024H-HRS33CO FPC-V1.0-20171215

Update: based on googling, the third element of the first part is most probably rather HRS3300, as this seems to be a known heart rate sensor. And “H-R-S” can be an acronym of a “Heart Rate Sensor”. Thus, the markings are probably rather:

AB220-SB1024H-HRS3300 FPC-V1.0-20171215

Interestingly, googling for SB1024H led me to a document on iget.eu website, and further googling up an “iGET FIT F4” seems to show images looking very similar to how the “Medion Life E1800” looks.
