ESP32-S3FN8
Espressif SystemsESP32-S3FN8 is the in-package-Flash variant of Espressif's ESP32-S3 SoC — dual-core Xtensa LX7 at 240 MHz with 2.4 GHz Wi-Fi 4 and Bluetooth 5 LE in the same 7 × 7 mm QFN-56 as the base chip, with 8 MB of quad Flash stacked inside the package. The in-package memory is the selection point: the board drops its external Flash chip, which simplifies the RF-adjacent layout and the BOM, at a −40 °C to +85 °C operating range. Selection advice: the FN8 code denotes 8 MB in-package Flash and no PSRAM — firmware and assets must fit the 8 MB alongside the OTA partitions, so confirm the image budget before committing. When the design needs working RAM more than storage, the ESP32-S3R8 on this site carries 8 MB of in-package PSRAM instead; the bare ESP32-S3 remains the pick when external memory is already planned.
