Existing BOM lines using this part can continue to be sourced through independent distribution; new designs should evaluate the current-generation ESP32-S3 or ESP32-C6 family for ongoing availability and security updates. ## 2.4 GHz TxRx + MCU — single-chip IoT edge node The ESP32-S0WD integrates a 2.4 GHz WiFi 802.11b/g/n and Bluetooth 4.2 transceiver with a Tensilica Xtensa LX6 MCU on a single die. This TxRx + MCU architecture eliminates the external host processor and separate radio chip for connected sensor nodes, smart-home gateways, and industrial wireless bridges. ## 34 GPIO — sensor and peripheral expansion With 34 GPIOs, the ESP32-S0WD drives parallel display buses, memory chip selects, and multiple sensor arrays without an external I/O expander. The pins are multiplexed with the I²C, I²S, SPI, and UART serial interfaces, so the actual usable GPIO count depends on which peripherals are enabled in firmware. ## 20 dBm output, -98 dBm sensitivity — link budget for range The 20 dBm transmit power delivers a strong signal through walls and enclosures; the -98 dBm receiver sensitivity captures packets at the noise floor. Combined with 150 Mbps max data rate, this part handles both long-range telemetry and high-throughput OTA firmware updates in the 2.4 GHz ISM band. The 48-VFQFN Exposed Pad package requires a thermal pad soldered to a ground-plane copper pour to keep the junction temperature within limits under continuous 240 mA transmit current. ## 3.3 V supply — single-rail integration The 100 mA receive current and 240 mA transmit current define the regulator sizing — a 500 mA LDO or buck converter with 3.3 V output provides margin for both radio bursts and GPIO load.","metaTitle":"ESP32-S0WD WiFi + Bluetooth 4.2 TxRx MCU, 2.4 GHz, NRND","metaDescription":"ESP32-S0WD from Espressif Systems — 2.4 GHz WiFi 802.11b/g/n + Bluetooth 4.2 TxRx MCU, 34 GPIO, -40°C to +125°C.
