 The modem is a Quectel BG95-M3 LTE MODEM with GPS. Both antennas are fitted and the usb of the modem is likely exposed to debug pads.
 
-The other sensors are 2 Acceleration Sensors(LIS3DH), a Light Sensor(VEML6035) next to the push button(that will allow the device to wake up from a low power state), a Temperature Sensor and Pressure sensor and a red and green led.

 The full schematic of the device will still need to be reversed and the sensors need to be properly identifyed. PRs are welcome.
