ESP32-H2 Specifications

芯片：esp32-h2 | 类别：specs | 信源： Espressif 官方文档

1. Core Architecture

• CPU: Single-core RISC-V, 96 MHz（303.38 CoreMark）— 全系列最低主频.
• Wireless: BLE 5.3, Zigbee/Thread (802.15.4). Note: No Wi-Fi support.
• Application: Smart home devices, Matter over Thread, low-power sensors — 超低功耗传感器节点.

2. Memory

• SRAM: 320 KB internal.
• LP Memory: 4 KB.
• ROM: 128 KB.
• 内置 Flash: 2 MB 或 4 MB QSPI.

3. Peripheral Mapping

• GPIO Count: 芯片 19 个，模组 WROOM-02C 19 个 / WROOM-07 仅 3 个.
• ADC: 5 channels, 12-bit（GPIO1–5）.
• DAC: None.
• Touch: None.
• Hardware PWM: LEDC 6ch + MCPWM.
• UART: 2 controllers.
