Notes
- 1.25mm battery interface with charge/discharge protection circuit (not JST); battery not included
- Rotary encoder with integrated confirm button, 24 detents, 12 pulses/360°
- Dual microphones; 8ohm 1W speaker; 7x ring RGB LEDs
- TF (microSD) card holder; 2.54mm 8-pin GPIO header
- Wi-Fi 802.11 b/g/n, Bluetooth 5 + Bluetooth mesh
- Official schematic labels the chip ESP32-S3R8 (8 MB Octal-SPI in-package PSRAM per Espressif's ESP32-S3 series datasheet); the R8 chip variant has no in-package flash, and the external flash chip's exact capacity is not identified in available LilyGO documentation, so flash_mb is left unset
- io.gpio_exposed=8 QUOTED: product page technical-specs list states "2.54 x 8pin GPIO interface" as a distinct connector, separate from the display/ encoder/mic/speaker/LED/SD/radio pins already fully enumerated (and none free) in the vendor pin-definition header (examples/factory/pin_config.h); io.gpio_free OMITTED because neither the product page nor the schematic PDF gives the individual GPIO numbers on that header, so subtracting esp32-s3's soc.reserved_pins cannot be done defensibly
