ESP32 WiFi-BT-BLE MCU Module ESP-WROOM-32

ESP32-WROOM-32 is Espressif’s all-in-one Wi-Fi + Bluetooth® Classic/BLE module built around a dual-core 32-bit MCU. It packs wireless, fast I/O, rich peripherals, and ample memory into a solderable module—ideal for connected sensors, gateways, wearables, and robotics in the Philippines. Use the Arduino IDE, ESP-IDF, or MicroPython to go from idea to prototype in minutes.

Dual-Core Wi-Fi + BLE in a Solderable Module — Small, Fast, Connected

  • Performance + wireless: dual-core Xtensa® up to 240 MHz with 2.4 GHz Wi-Fi and Bluetooth Classic/BLE.
  • Rich analog & timers: 12-bit ADC channels, 2× 8-bit DACs, capacitive touch, and flexible PWM.
  • Robust I/O: SPI, I²C, I²S, UART, CAN* (via external transceiver), and hardware crypto/security engines.
  • Pro-friendly: metal-can module with integrated antenna, 3.3 V supply, and castellated pads for SMT reflow.
  • Works your way: Arduino, ESP-IDF (FreeRTOS), and MicroPython ecosystems with huge community support.

What you can build

  • IoT nodes & gateways: Wi-Fi telemetry + BLE provisioning; add environment/ToF/IMU sensors
  • Wearables & remotes: BLE HID keyboards/macro pads, low-latency BLE controllers
  • Data loggers: high-rate ADC capture to microSD (SPI), upload via Wi-Fi/MQTT
  • Robotics: PWM motor/servo control with wireless teleop; OLED/TFT status UIs

Certifications Common WROOM-32 variants carry FCC/CE/IC (check batch/product label)

*CAN requires an external CAN transceiver (e.g., SN65HVD230) connected to ESP32’s TWAI/CAN pins.

Pinout & power notes

  • 3.3 V only: I/O is not 5 V-tolerant—use level shifters with 5 V peripherals.
  • ADC2 & Wi-Fi: ADC2 channels are unavailable while Wi-Fi is active; use ADC1 for continuous sampling.
  • Bootstrap pins: avoid pulling GPIO 0, 2, 5, 12–15 to the wrong levels at reset (affects boot mode).
  • Power design: use a low-noise 3.3 V regulator with ≥600 mA peak and place 10–100 µF bulk caps near the module.
  • Programming: connect EN/BOOT (IO0) with proper pull-ups/downs, or use a USB-to-UART board that auto-resets (DTR/RTS).

What’s in the box

FAQs – ESP32-WROOM-32 Module (Philippines)

Is this a development board with USB?
No—this is the bare module. For USB + regulator + headers, see our ESP32 DevKit boards.
How do I program the module?
Use a USB-to-UART bridge (3.3 V) wired to TX0/RX0, EN, and IO0. The Arduino IDE, ESP-IDF, and MicroPython are supported.
What power supply do I need?
A clean 3.3 V rail with headroom for RF peaks. We recommend a regulator rated ≥600 mA, short traces, and local bulk capacitors.
Does it support Bluetooth® and BLE?
Yes—ESP32 supports both Bluetooth® Classic and Bluetooth® Low Energy (BLE 4.2).
Do you ship nationwide?
Yes—nationwide shipping across the Philippines via trusted couriers, with fast dispatch for Metro Manila orders.
