ESP32-MINI-1U

ESP32-MINI-1U is a compact Wi-Fi + Bluetooth + Bluetooth LE module based on the ESP32-U4WDH chip, featuring an IPEX antenna connector for flexible placement in space-constrained IoT applications.

• Small size: 13.2 x 13.5 x 2.4 mm
• 2.4 GHz Wi-Fi and Bluetooth Classic/LE
• Rich set of peripherals
• Wide operating temperature range: -40°C ~ 85°C
• IPEX antenna connector for external antennas
• Perfect for smart home, building, and industrial control

The ESP32-MINI-1U series delivers the same ultra-compact power of the ESP32-MINI-1, but with one key upgrade-an external antenna connector (U.FL/IPEX). This gives you the flexibility to use high-gain or specialized antennas, boosting wireless range and improving signal reliability in challenging environments.

Compared to the standard MINI-1 with its onboard antenna, the MINI-1U is better suited for metal enclosures, long-range deployments, or installations where signal penetration is critical. You still get the full ESP32 feature set-dual-core processor, Wi-Fi, Bluetooth, and low power consumption-in a PCB footprint small enough for wearables, handheld devices, and compact IoT products.

Available variants:

• N4: Standard 4MB flash version, ideal for small, space-conscious projects that need maximum wireless flexibility.
• H4: High-temperature 4MB flash variant for industrial or outdoor applications where heat resilience is essential.

In short-ESP32-MINI-1U gives you compact size, powerful features, and antenna flexibility. Perfect when you need MINI-1 performance but with stronger, more adaptable wireless capabilities.
