ESP-WROOM-32
Overview
The ESP-WROOM-32 is an Espressif WiFi + BLE module that integrates an ESP32 dual-core MCU (up to 240 MHz), 4 MB of external flash, and a PCB antenna. It provides a compact, ready-made radio and MCU combination for connected products and prototypes. The module exposes GPIOs and peripheral signals for sensors, actuators, and external interfaces.
Why Choose This Part
The ESP-WROOM-32 combines a capable dual-core ESP32 SoC with an integrated radio and flash in a single certified module, reducing design and RF testing effort. It has wide software support (Espressif ESP-IDF and community Arduino core) and an active ecosystem of libraries and examples, which speeds development. The module form-factor and exposed I/O make it easy to integrate into custom PCBs or use on dev boards for prototyping.
Applications
Getting Started
Start with Espressif development kits such as the ESP32-DevKitC which break out the module pins and include a USB-to-UART interface for flashing. Use the Espressif ESP-IDF toolchain for full-featured development or the Arduino core for simpler sketches; flashing and debugging commonly use esptool.py and OpenOCD for supported boards. Ensure your target board provides a stable 3.3 V supply and the required CP210x/FTDI/CH340 USB-UART bridge or programmer when using development kits.
Also Consider
Espressif
- Version that exposes a u.FL connector option for using an external antenna instead of the onboard PCB antenna.
Espressif
- Module that adds onboard PSRAM in addition to flash, useful for applications that need more RAM for buffering or image processing.
