It integrates a PCB trace antenna, eliminating the need for an external antenna in space-constrained designs, and delivers a transmit output power of 19.5 dBm with a receive sensitivity of -97 dBm. ## Memory, sensitivity, and power budget for BOM fit On-chip memory comprises 128 kB ROM and 320 kB SRAM, sufficient for lightweight TCP/IP stacks and application code without external RAM in many IoT endpoints. The -97 dBm receive sensitivity at the 1 Mbps data rate gives the module usable range in indoor environments where path loss through walls and floors is a factor; the 19.5 dBm TX power pushes the link budget past 30 dBm, enough for a 50-100 meter line-of-sight link in most residential or light-commercial deployments. ## Package, supply, and temperature grade for board integration Supply voltage is 3 V to 3.6 V, compatible with standard 3.3 V rails; the module's internal LDOs regulate down to the core voltage, so a clean 3.3 V supply with adequate decoupling at the VDD pins is the primary board-level requirement. ## Serial interfaces and GPIO routing flexibility The ESP32-S2 provides a rich set of serial interfaces accessible through the module's pins: ADC, GPIO, I²C, I²S, SPI, PWM, UART, and USB — allowing connection to sensors, displays, audio codecs, and external memory without an external bridge chip. The USB interface supports direct programming and serial debug via a USB-to-UART bridge on the host side, eliminating the need for a separate JTAG probe during development.","metaTitle":"ESP32-S2-MINI-1-N4 WiFi Module, 150 Mbps, -97 dBm","metaDescription":"Espressif Systems ESP32-S2-MINI-1-N4 WiFi module, 150 Mbps data rate, -97 dBm sensitivity, 19.5 dBm TX power.
