Description :

Operating at 2.4 GHz, the ESP32-S3-WROOM-1-N4 supports IEEE 802.11 b/g/n Wi-Fi and Bluetooth 5 (LE) standards, offering reliable high-speed data transmission up to 150 Mbps. It integrates 4 MB flash memory, 384 kB ROM, and supports multiple serial interfaces including UART, SPI, I²C, I²S, PWM, USB, and GPIO, making it ideal for complex embedded designs.
With an RF output power of 20.5 dBm and receiver sensitivity down to –103.5 dBm, this module ensures stable wireless performance even in demanding environments. The low-power design, combined with support for deep sleep modes, makes it suitable for battery-powered and energy-efficient applications.

The ESP32-S3-WROOM-1-N4 is fully surface-mountable (SMD) and supplied in Tape & Reel packaging, optimized for automated production lines.
