It implements 802.11b/g/n at a data rate up to 150 Mbps in the 2.412 GHz to 2.484 GHz band. Transmit power reaches 19.5 dBm, and receiver sensitivity is -97 dBm, giving a link budget that supports reliable connections through walls and across typical indoor ranges. On-chip memory comprises 128 kB ROM and 320 kB SRAM, sufficient for lightweight TCP/IP stacks and application logic without external RAM in many IoT endpoints. ## Supply, interfaces, and temperature grade Supply voltage range is 3 V to 3.6 V, compatible with common 3.3 V rails. Current draw during reception is 63 mA to 68 mA; during transmission it ranges from 160 mA to 310 mA depending on output power setting. Serial interfaces include ADC, GPIO, I²C, I²S, SPI, PWM, UART, and USB, covering sensor readout, display driving, and peripheral control without a separate host MCU. Housed in a 65-SMD module, the part is surface-mount and does not include an integrated antenna — the board layout must provide a suitable antenna trace or external antenna connector.","metaTitle":"ESP32-S2-MINI-1U-N4 WiFi Module, 802.11b/g/n, 150Mbps","metaDescription":"Espressif Systems ESP32-S2-MINI-1U-N4 WiFi module, 802.11b/g/n, 150Mbps, 2.412-2.484GHz, 19.5dBm TX power, -97dBm RX sensitivity, 128kB ROM, 320kB SRAM, -40°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":"2.412GHz ~ 2.484GHz","Modulation":"-","Memory Size":"128kB ROM, 320kB SRAM","Sensitivity":"-97dBm","Antenna Type":"Antenna Not Included","Mounting Type":"Surface Mount","Package / Case":"65-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","Base Product Number":"ESP32-S2","Current - Receiving":"63mA ~ 68mA","Operating Temperature":"-40°C~85°C","Current - Transmitting":"160mA ~ 310mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.1800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b786d69639584a7455b99ce41a3ccb15.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ESP32-S2-MINI-1U-N4/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/espressif/ESP32-S2-MINI-1U-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-MINI-1U-N4 when reusing this data.
