High Temperature option is NOT for new designs.
The Espressif ESP-WROOM-32U is a powerful and compact module that combines Wi-Fi, Bluetooth (BT), and Bluetooth Low Energy (BLE) to support a wide range of applications. The module boasts a U.FL (IPEX) connector making the module perfect for space-constrained applications.
By integrating the ESP32-D0WD chip, the device offers a dual-core CPU with an adjustable clock frequency (80 MHz to 240 MHz) and can be individually controlled and powered. The CPU may also be powered off to make use of the low power co-processor to continuously monitor the peripherals for a change of state.
Some of the powerful peripherals integrated within the ESP32-D0WD include:
- Capacitive touch sensors
- Hall sensors
- SD card interface
- Ethernet
- High speed SPI
- UART
- I²S
- I²C
- Low-noise sense amplifiers
The WROOM-32U operates on freeRTOS with LwIP; TLS 1.2 with hardware acceleration built-in. The module includes secure encrypted over-the-air (OTA) updates, allowing developers to continually upgrade their products after release with low cost and effort.
The system is completely open-source with a large collection of example code and information on GitHub.
Common applications include:
- Home automation
- Wearable electronics
- Sensor networks
- Internet of Things (IoT) solutions
- Voice encoding
- Music streaming
- MP3 decoding
Features
- Combo Wi-Fi, Bluetooth (BT), and Bluetooth Low Energy (BLE) module
- Integrates with the ESP32-D0WD chip
- Two independently controlled CPU cores with adjustable clock frequency from 80MHz to 240MHz
- Sleep current is less than 5 μA, making it suitable for battery-powered and wearable-electronics applications
- 4-layer FCC, CE ( RED ), IC, TELEC, SRRC, and KCC-compliant design
Classic Bluetooth for legacy connections, supporting:
- L2CAP
- SDP
- GAP
- SMP
- AVDTP
- AVCTP
- A2DP (SNK)
- AVRCP
- Including BLE GATT-based profiles, such as BlueFi, SPP-like, etc.
- Bluetooth Low Energy (BLE) connects to smart phones, broadcasting low-energy beacons for easy detection
- Wi-Fi modes: Soft-AP/Station/SoftAP+Station/P2P
