{"title":"ESP-WROOM-32 (ESP32 WiFi-BT-BLE MCU Module)","handle":"esp-wroom-32-esp32-wifi-bt-ble-mcu-module","url":"/products/esp-wroom-32-esp32-wifi-bt-ble-mcu-module","description":"The ESP-WROOM-32 is Espressif's powerful Wi-Fi, Bluetooth Classic, and BLE module built around the ESP32 dual-core processor. It's a versatile platform for IoT applications ranging from low-power sensor networks to demanding tasks like voice encoding, music streaming, and MP3 decoding.\n\nThis is the bare module with 1.27 mm pitch castellated pads — designed for soldering onto a custom PCB with supporting circuitry. Certified for FCC, CE, IC, MIC (Telec), KCC, and NCC.\n\n\nWarning: This is the raw module only — not a development board. You will need to design or use a carrier board with power regulation, USB interface, and boot/reset circuitry. If you want a ready-to-use board, look for an ESP32 development board instead.\n\n\nKey Features\n\n\nDual-Core Xtensa LX6 – Two 32-bit processors for parallel processing\n\nWi-Fi 802.11 b/g/n – Up to 150 Mbps, Station/SoftAP/P2P modes\n\nBluetooth v4.2 – Both Classic BR/EDR and BLE\n\nRich Peripheral Set – UART, SPI, SDIO, I2C, I2S, PWM, ADC, DAC, touch sensor, Hall sensor, and more\n\nSecurity – WPA/WPA2/WPA2-Enterprise, AES/RSA/ECC/SHA encryption\n\nNetwork Protocols – IPv4, IPv6, SSL, TCP/UDP/HTTP/FTP/MQTT\n\n\nSpecifications\n\n\nProcessor: Dual Xtensa 32-bit LX6\n\nROM: 448 KB (boot and core functions)\n\nSRAM: 520 KB on-chip + 8 KB RTC SLOW + 8 KB RTC FAST\n\neFuse: 1 Kbit (256-bit MAC)\n\nWi-Fi: 802.11 b/g/n/d/e/i/k/r (up to 150 Mbps)\n\nBluetooth: v4.2 BR/EDR + BLE\n\nOperating Voltage: 2.2–3.6 V\n\nTypical Current: 80 mA\n\nOperating Temperature: −40 °C to +85 °C\n\nDimensions: 18 × 25.5 × 2.8 mm\n\nPin Pitch: 1.27 mm\n\nPCB Thickness: 0.8 ± 0.1 mm\n\n\nInterfaces\n\nSD card, UART, SPI, SDIO, I2C\nLED PWM, Motor PWM, I2S, IR\nGPIO, Capacitive Touch Sensor\nADC, DAC, Hall Sensor, Temperature Sensor\n\n\nPackage Contents\n\n1× ESP-WROOM-32 Module\n\n\nResources\n\nDatasheet (PDF)\n","vendor":"Elecrow","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3502,"title":"Default Title","sku":"EC-WCW32110W","price":13.41,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":108,"option1":"Default Title"}]}
