Open the original- What it measures
- PIE is the vector instruction set that Espressif also calls SIMD in this note. The entry is dated 9 October 2026 and is part of the esp-sr 2.6.0 release notes.
- What it does not show
- Wake word detection only. The same README still lists the original ESP32 outside the MultiNet command-recognition table, so a wake word and a command list are different capabilities on that chip.
