At free-space path loss, this combination yields a link margin of roughly 117.5 dB — enough for a 400+ metre line-of-sight link at 1 Mbps using a 0 dBi antenna. The real-world range depends on the antenna match and the environment; fix the pi-network match before blaming the firmware. It integrates a 2.4 GHz transceiver with 802.11b/g/n (HT20/HT40) and Bluetooth v4.2 + EDR, supporting 8DPSK, DSSS, DQPSK, and OFDM modulations. The 150 Mbps PHY rate is the ceiling; actual throughput is limited by the host interface and stack overhead. ## Memory headroom and GPIO budget With 2 MB PSRAM and 536 kB on-chip SRAM, the part can hold a full Wi-Fi/BLE stack plus a moderate application heap — roughly 1.5 MB available for user data after the protocol stacks. The 34 GPIOs map to ADC, I²C, I²S, SDIO, SPI, PWM, and UART interfaces, enough for a sensor cluster or a display with a parallel bus. Espressif lists the ESP32-D0WDR2-V3 as Active.","metaTitle":"ESP32-D0WDR2-V3 RF & Wireless IC – 2.4 GHz Wi-Fi/BLE SoC","metaDescription":"ESP32-D0WDR2-V3 from Espressif Systems: TxRx + MCU, 2.4 GHz, 802.11b/g/n + BLE v4.2, 19.5 dBm TX, -98 dBm sensitivity, 2 MB PSRAM, 34 GPIO, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["RF & Wireless ICs"],"specifications":{"Mfr":"Espressif Systems","GPIO":"34","Type":"TxRx + MCU","Series":"ESP32","Package":"Tape & Reel (TR); Cut Tape (CT)","Protocol":"802.11b/g/n, Bluetooth v4.2 + EDR, Class 1, 2 and 3","Frequency":"2.4GHz","Modulation":"8DPSK, DSSS, DQPSK, OFDM","Memory Size":"2MB PSRAM, 448kB ROM, 536kB SRAM","Sensitivity":"-98dBm","Mounting Type":"Surface Mount","Package / Case":"48-VFQFN Exposed Pad","Power - Output":"19.5dBm","Product Status":"Active","Data Rate (Max)":"150Mbps","lifecycle_stage":"eol_hot","Voltage - Supply":"2.3V ~ 3.6V","Serial Interfaces":"ADC, GPIO, I²C, I²S, SDIO, SPI, PWM, UART","RF Family/Standard":"Bluetooth, WiFi","Current - Receiving":"95mA ~ 100mA","Operating Temperature":"-40°C~125°C","Current - Transmitting":"130mA ~ 240mA","Supplier Device Package":"48-QFN (5x5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.9200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d8bda4b35ca2182e7e30932f6e7d0a45.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ESP32-D0WDR2-V3/alternatives.json"},"ai":{"faq":[{"question":"What are the key differences between ESP32-D0WDR2-V3 and ESP32-D0WD?","answer":"The ESP32-D0WDR2-V3 adds 2 MB PSRAM versus the ESP32-D0WD which has no PSRAM. Both share the same 48-QFN footprint and GPIO count. The V3 variant also carries the wider -40°C to 125°C temperature range compared to the standard -40°C to 85°C on the D0WD. Pin compatibility is identical, so a D0WD layout accepts the D0WDR2-V3 if the PSRAM supply rails are present."},{"question":"Does the ESP32-D0WDR2-V3 include the full Wi-Fi and Bluetooth stack?","answer":"Yes.
