Connect ESP32 hardware to Nodrix in a few lines — NODRIX_WRITE control handlers with typed values, one-call telemetry, WebSocket and HTTP transports, at-least-once delivery, and optional TLS pinning.
iotta codec-board audio IO — ES8311 DAC + ES7210 mic-array ADC over a shared full-duplex I2S bus (esp_codec_dev). Optional Build-B voice backend for the iotta device SDK; wire via Esp32Platform::set_audio().
