A reverse-engineering workspace for the EP-2350 Ting FX microphone, which is built on a Raspberry Pi RP2350. It records facts such as the dual Cortex-M33 SoC, a Pico SDK and TinyUSB toolchain, a MicroPython 1.26.0 preview runtime and the USB descriptors in app and boot modes. The author says everything comes from publicly downloadable firmware and read-only observation, and nothing in it writes to the hardware.
