Found this tracking device literally in the middle of the road. Housing was a bit beaten up, circuitry looks fine. SIM installed, UART at the bottom, USB test points on the left, 2x microphone, BT, WiFi, and GSM antennas. Yes, I've disconnected the battery (it was dead).

TOP SECRET! This year's #DEFCON 27 Badge uses an @NXP KL27 ARM Cortex-M0+ (among other things). For most efficient hacking, use an LPC-Link2, @TagConnect TC2050-IDC-NL-050-ALL (normal orientation), and 1.8V-compatible level translator or USB-to-Serial adapter.
