ESP32-S3-WROOM-1/1U Modules

Espressif Systems ESP32-S3-WROOM-1/1U Modules are 2.4GHz Wi-Fi^® (802.11 b/g/n) and BLUETOOTH^® 5 (LE) modules built around the ESP32S3 series of SoCs and Xtensa® dual-core 32bit LX7 microprocessor. The ESP32-S3-WROOM-1/1U provides acceleration for neural network computing and signal processing workloads. The ESP32-S3-WROOM-1/1U Modules feature flash up to 16MB, PSRAM up to 8MB, 36 GPIOs, and a rich set of peripherals. Additionally, the devices have an onboard PCB antenna (ESP32-S3-WROOM-1) or an external antenna connector (ESP32-S3-WROOM-1U).
