Description
Espressif WROOM-1 SiP module integrating the ESP32-S3 SoC, 8 MB external flash and 8 MB octal-mode PSRAM, a 2.4 GHz PCB antenna, RF front-end and the regulatory shield. Used as the radio core of the ESP32-S3-DevKitC-1. GPIO33–GPIO37 are reserved internally for the octal PSRAM bus on the N8R8 variant and are not brought out at the module level.
