The UNIT PULSAR ESP32 H2 is a cutting-edge development board designed for IoT applications, leveraging the powerful ESP32 H2 microcontroller. Inspired by the arduino nano form factor, this board is perfect for developers looking to create compact and efficient solutions.
The PULSAR NANO ESP32-H2 is a compact, powerful development board based on the ESP32-H2. It keeps the Arduino Nano form factor and the same pin distribution, making it easy to integrate with existing shields and projects.
Key features:
- Bluetooth 5 (LE) and IEEE 802.15.4 radio for Thread and Zigbee.
- Matter over Thread support for modern smart-home ecosystems.
- Onboard LiPo charger.
- MicroSD card socket for external storage.
- QWIIC connector for plug-and-play I²C sensors/modules.
- Onboard WS2812-2020 Neopixel LED for visual feedback.
Note: The ESP32-H2 does not include Wi-Fi. For Wi-Fi/Ethernet backhaul (e.g., border-router scenarios), pair this board with a companion device that provides that connectivity.
