# PULSAR NANO ESP32-H2
23+
24+
## Descripción
25+
26+
La **PULSAR NANO ESP32-H2** es una tarjeta de desarrollo compacta y potente basada en el **ESP32-H2**. Mantiene el **formato Arduino Nano** y la misma **distribución de pines**, facilitando la integración con shields y proyectos existentes.
27+
28+
Características clave:
29+
- Radio **Bluetooth 5 (LE)** y **IEEE 802.15.4** para **Thread** y **Zigbee**.
30+
- Compatible con **Matter over Thread** para ecosistemas de hogar inteligente modernos.
31+
- Cargador LiPo integrado.
32+
- Conector **MicroSD** para almacenamiento externo.
33+
- Conector **QWIIC** para sensores y módulos I²C.
34+
- **LED Neopixel WS2812-2020** a bordo para retroalimentación visual.
35+
36+
> **Nota:** El **ESP32-H2 no incluye Wi-Fi**. Para escenarios con backhaul Wi-Fi/Ethernet (p. ej., *border router*), empareja esta placa con un dispositivo complementario que provea esa conectividad.
