You know a piece of tech is going to be fun to take apart when it makes you go buy a new set of bits just to be able to open it

@stilescrisis I recognized it as a GPS/GNSS module, and I've ordered breakout boards for these before. Things like this:
Gravity: GNSS GPS BeiDou Receiver Module - I2C&UART
This GNSS receiver module from DFRobot supports BeiDou, GPS, QZSS and other multi-satellite systems. It compatible with Arduino, ESP32, micro:bit and Raspberry Pi, which can be widely applied to outdoor positioning scenarios such as vehicle navigation,

@foone but isn't it possible theirs has better reception or lower battery consumption or something like that?
-
@stilescrisis not really? it's the same chip, they just put a different connector on it.
-
Missed a chip! There's an Nordic Semiconductor nRF52840 SoC on the back.
That's a Bluetooth/BLE/NFC/Zigbee chip.
(It's also an ARM Cortex M4. ) -
So I searched for "Lyft ebike" and this image came up. Apparently in 2021 they were testing these out, and it looks like the actual released product is basically this thing but inside a plastic enclosure.
So either this is just the internals, or this is a prototype for something they later built.

@foone how many CPUs does this bike have?
-
@ClaireH Five, I think

@foone @stilescrisis okay forget the lyft thing, now i am wondering why this board has a switch for turning off gravity

@vfig @stilescrisis heh.
Actually the module is named "Gravity" and that switch is for selecting which interface to use, i²C or UART

@foone christ how many radios does this thing have
-
@cinebox what radios does it NOT have?

@foone wow I heard that as if @logicalelegance read an intro for the Lockpicking Lawyer

@vk2tty @logicalelegance I have had to lockpick more than one old computer, amusingly
