The 536 kB of on-chip SRAM and 448 kB of ROM handle the real-time OS kernel and peripheral DMA descriptors, leaving the external PSRAM for heap-allocated data like web server content or sensor logs. ## RF link budget and antenna integration With a transmit power of 19.5 dBm and a receiver sensitivity of -97 dBm, the module delivers a usable link budget of roughly 116 dB for 802.11b 1 Mbps — enough for a 200-meter line-of-sight link in open air, though the PCB trace antenna pattern and enclosure losses will reduce that in practice. The module supports 802.11b/g/n at 150 Mbps PHY rate and Bluetooth v4.2 with EDR, covering the common IoT connectivity stack for smart-home, industrial sensor, and retail applications. ## Current consumption profile Receive current ranges from 111 mA to 117 mA, while transmit current can reach 248 mA to 368 mA depending on the output power level and protocol — the 3.3 V rail must be sized for the peak transmit current plus a 20-30% margin to avoid droop during a Wi-Fi burst.","metaTitle":"ESP32-PICO-MINI-02U-N8R2 Espressif Systems, 8MB Flash","metaDescription":"ESP32-PICO-MINI-02U-N8R2 module by Espressif Systems. 8MB Flash, 2MB PSRAM, 2.4 GHz WiFi & BLE 4.2, PCB trace antenna, -97 dBm sensitivity, -40°C 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, Bluetooth v4.2 +EDR, Class 1, 2 and 3","Data Rate":"150Mbps","Frequency":"2.4GHz","Modulation":"8DPSK, DQPSK","Memory Size":"8MB Flash, 2MB PSRAM, 448kB ROM, 536kB SRAM","Sensitivity":"-97dBm","Antenna Type":"PCB Trace","Mounting Type":"Surface Mount","Package / Case":"53-SMD Module","Power - Output":"19.5dBm","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"3V ~ 3.6V","Serial Interfaces":"ADC, GPIO, I²C, I²S, SDIO, SPI, PWM, UART","RF Family/Standard":"Bluetooth, WiFi","Utilized IC / Part":"ESP32-PICO-V3-02","Current - Receiving":"111mA ~ 117mA","Operating Temperature":"-40°C~85°C(TA)","Current - Transmitting":"248mA ~ 368mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.9800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b8217fc7bb0dc4e2059750b7e303fcd5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ESP32-PICO-MINI-02U-N8R2/alternatives.json"},"ai":{"faq":[{"question":"What is the utilized IC inside the ESP32-PICO-MINI-02U-N8R2 module?","answer":"The module integrates the ESP32-PICO-V3-02 silicon, which is a system-in-package (SiP) containing the ESP32 dual-core MCU, flash, PSRAM, and RF front-end in a single substrate."},{"question":"What serial interfaces does the ESP32-PICO-MINI-02U-N8R2 support?","answer":"It provides ADC, GPIO, I²C, I²S, SDIO, SPI, PWM, and UART interfaces, covering the common peripheral set for sensor readout, audio codec connection, SD card storage, and display control."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/espressif/ESP32-PICO-MINI-02U-N8R2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/espressif/ESP32-PICO-MINI-02U-N8R2 when reusing this data.
