Product FAQ

  • 1. What Compliance Standards Does the Esp32-wroom-32e-n4 Meet?
    The module is RoHS compliant, ensuring it meets environmental and hazardous substance restrictions for commercial and industrial use. For additional certification information, operating temperature ranges, and reliability specifications, refer to the product datasheet.
  • 2. Is the Esp32-wroom-32e-n4 Compatible with Other ESP32 Modules?
    The ESP32‑WROOM‑32E‑N4 shares the same form factor and pin count as other modules in the ESP32‑WROOM series. However, designers should verify memory size, antenna type, and other specifications in the datasheet before treating any ESP32 module as a direct drop‑in replacement, as internal configurations may differ.
  • 3. What Wireless Connectivity Does the Esp32-wroom-32e-n4 Provide?
    This module combines 2.4 GHz Wi‑Fi, Bluetooth, and Bluetooth Low Energy (BLE) in a single component, making it suitable for applications requiring dual wireless protocols. The integrated PCB antenna simplifies board design and reduces external component count compared to modules requiring external antenna connectors.
  • 4. What Are the Key Specifications of the Esp32-wroom-32e-n4 Wi-fi and Bluetooth Module?
    The ESP32‑WROOM‑32E‑N4 is a 2.4 GHz Wi‑Fi + Bluetooth + Bluetooth LE module based on the ESP32‑D0WD series SoC. It operates at 3.0–3.6 V, delivers up to 20 dBm output power, features an on‑board PCB antenna, and is housed in a compact SMD package (25.5 × 18 mm). For detailed memory specifications, I/O pin configuration, and additional technical parameters, consult the datasheet.
