The 150 Mbps PHY rate on 802.11b/g/n at 2.4 GHz supports real-time sensor streaming or OTA update payloads over a single spatial stream. ## Industrial temperature grade and RF link budget The receiver sensitivity of -97 dBm and a transmit output of 19.5 dBm combine for a link budget that clears 300+ meters line-of-sight in a clean 2.4 GHz band — useful for warehouse or campus deployments where the AP is not in the same room. ## Peripheral set and PCB integration The module exposes ADC, GPIO, I²C, I²S, SPI, PWM, UART, and USB serial interfaces through the 56-VFQFN exposed-pad package. The PCB trace antenna eliminates the cost and tuning of an external ceramic chip — the ground plane clearance and keep-out zone under the antenna edge must follow Espressif's layout guide to hit the -97 dBm sensitivity floor. ## Active lifecycle and supply posture Marked as Active by Espressif — this is a current-production module suitable for new designs and volume builds.","metaTitle":"Espressif ESP32-S2-MINI-2-N4 WiFi Module, 4MB Flash, 2.4GHz","metaDescription":"Active Espressif ESP32-S2-MINI-2-N4 WiFi module with 4MB flash, 2.4GHz 802.11b/g/n, 150Mbps data rate, -40°C to 105°C range.
