ESP32-H4 supports all Bluetooth 5.4 (LE) features and is certified for Bluetooth 6.0, marking a key milestone for Espressif.
Built on a dual-core 32-bit RISC-V MCU (up to 96 MHz), it integrates Bluetooth 5.4 (LE) and IEEE 802.15.4, supporting Thread, Zigbee, Matter, and Bluetooth Mesh. With BLE Audio, ESP32-H4 enables new use cases in wireless audio, indoor positioning, and large-scale sensor networks.
ESP32-H4 features an integrated DC-DC converter and optimized power management, making it ideal for wearables and long-life loT devices.
Key capabilities include:
- LE Audio for low-power audio devices (earbuds, speakers, hearing aids)
- Isochronous Channels (BIS/CIS) for synchronized audio streaming and broadcast
- Connection Subrating for reduced power consumption with responsive latency
- PAwR for scalable, low-power sensor networks
- Direction Finding (AoA/AoD) for accurate indoor positioning
