It integrates a 2.4 GHz 802.11b/g/n radio with a PCB trace antenna, delivering a data rate of 150 Mbps and a transmit output power of 19.5 dBm. On-chip memory includes 4 MB Flash and 2 MB PSRAM, plus 128 kB ROM and 336 kB SRAM, providing enough headroom for application code and data buffers in IoT sensor nodes, edge gateways, and smart-home controllers. ## RF performance and power budget Receiver sensitivity is rated at -97 dBm, which gives usable link margin in noisy indoor environments. The module draws 63 mA to 68 mA in receive mode and 160 mA to 310 mA during transmit, depending on output power level. ## Package, interfaces, and board integration Housed in a 56-VFQFN exposed-pad package (surface mount), the module requires careful thermal pad soldering for heat dissipation. The PCB trace antenna is integrated on the module substrate, so no external antenna matching network is needed for most layouts. Serial interfaces include ADC, GPIO, I²C, I²S, SPI, PWM, UART, and USB, giving flexibility for sensor fusion, display drivers, and wired communication links on a single module.","metaTitle":"Espressif ESP32-S2-MINI-2-N4R2 WiFi Module, 4MB Flash","metaDescription":"Active-production ESP32-S2-MINI-2-N4R2 WiFi module with 4MB Flash, 2MB PSRAM, 150Mbps 802.11b/g/n, -97dBm sensitivity, 19.5dBm output.
