It supports 802.11b/g/n at 2.4 GHz with a maximum data rate of 150 Mbps, a receiver sensitivity of -97 dBm, and a transmit power of 19.5 dBm — sufficient for indoor and short-range outdoor links with a clear line-of-sight budget. ## Memory and peripheral integration for embedded control With 4 MB on-board flash and 336 kB SRAM, the module can host a full TCP/IP stack and application code without external memory for many IoT endpoints — the flash holds firmware and configuration data, while the SRAM supports the runtime heap and stack. The serial interface set includes ADC, GPIO, I²C, I²S, SPI, PWM, UART, and USB, allowing direct connection to sensors, displays, and actuators without an external microcontroller. ## Package, antenna options, and temperature grade Antenna options include an on-board PCB trace antenna and an IPEX connector for an external antenna — the PCB trace saves cost and space in compact designs, while the IPEX port allows a remote antenna for better RF placement.","metaTitle":"ESP32-S2-SOLO-U-N4 WiFi Module, 2.4 GHz, 150 Mbps","metaDescription":"Espressif Systems ESP32-S2-SOLO-U-N4 WiFi module, 2.4 GHz 802.11b/g/n, 150 Mbps data rate, 4 MB flash, 336 kB SRAM, -40 to +85 °C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF & Wireless ICs"],"specifications":{"Mfr":"Espressif Systems","Series":"ESP32","Package":"Tape & Reel (TR); Cut Tape (CT)","Protocol":"802.11b/g/n","Data Rate":"150Mbps","Frequency":"2.4GHz","Modulation":"-","Memory Size":"4MB Flash, 128kB ROM, 336kB SRAM","Sensitivity":"-97dBm","Antenna Type":"PCB Trace + IPEX","Mounting Type":"Surface Mount","Package / Case":"40-SMD Module","Power - Output":"19.5dBm","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Serial Interfaces":"ADC, GPIO, I²C, I²S, SPI, PWM, UART, USB","RF Family/Standard":"WiFi","Utilized IC / Part":"ESP32-S2","Current - Receiving":"71mA ~ 75mA","Operating Temperature":"-40°C~85°C(TA)","Current - Transmitting":"165mA ~ 310mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6bf4d9e814ff72b06259e949c58b1913.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the memory configuration of ESP32-S2-SOLO-U-N4?","answer":"It integrates 4 MB flash, 128 kB ROM, and 336 kB SRAM on the module, sufficient for many single-chip IoT applications without external memory."},{"question":"What wireless standards does ESP32-S2-SOLO-U-N4 support?","answer":"It supports 802.11b/g/n at 2.4 GHz with a maximum data rate of 150 Mbps, a receiver sensitivity of -97 dBm, and a transmit power of 19.5 dBm."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/espressif/ESP32-S2-SOLO-U-N4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/espressif/ESP32-S2-SOLO-U-N4 when reusing this data.
