微雪（Waveshare）推出 ESP32-C5-Touch-LCD-3.5，又一款内置显示屏的 ESP32-C5 开发板，配备更大的 3.5 英寸彩色触控 LCD，并可选配 BF3901 低分辨率（0.08MP）摄像头和/或 500mAh 电池。
板上还提供扬声器接口与内置麦克风用于语音交互、六轴 IMU、温湿度传感器、microSD 卡槽以及 32 针 GPIO 扩展排针。
主要规格
无线模组为乐鑫 ESP32-C5-WROOM-1U-N32R8，SoC 为 ESP32-C5HR8：单核 32 位 RISC-V 处理器最高 240MHz，另有一颗 40MHz 低功耗 RISC-V 核作为功耗敏感场景的主处理器；片上 384KB SRAM、8MB PSRAM、320KB ROM。无线支持双频（2.4GHz/5GHz）802.11ax Wi-Fi 6（可回退 802.11b/g/n）、蓝牙 5.0 LE，以及用于 Zigbee 3.0 与 Thread 1.3 的 802.15.4 射频。模组带 32MB Flash 与 IPEX 天线连接器。
显示方面，官方规格表标注为 262K 色 IPS 屏、480×320 分辨率、电容触控，采用 ST7796 SPI 显示控制器与 FT6336 I2C 触控控制器（正文标题按板卡实物为 3.5 英寸）。摄像头为可选 BF3901，分辨率 320×240。音频链路包含板载 MEMS 麦克风、2 针扬声器接口、ES8311 低功耗音频编解码器与 NS4150B 音频功放。USB 为 Type-C，兼顾供电、烧录与数据。传感器包括 SHTC3 温湿度传感器与 QMI8658 六轴 IMU。扩展为 32 针 2.54mm 间距排针，引出 GPIO、UART、I2C 等。其他还有电源/复位/BOOT 按键、电源与充电 LED、PCF85063 RTC。供电可由 USB-C 5V 提供，或通过 2 针接口接入 3.7V 锂电池，由 AXP2101 电源管理芯片支持。板尺寸为 95.11×63.67×14.10mm。
规格与 7 月报道过的 ESP32-C5-Touch-LCD-2.8 相当接近，区别在于屏幕更大、分辨率更高，改用 IPEX 天线（而非 PCB 天线），增加可选摄像头、32 针 GPIO 排针，以及更高级的 AXP2101 PMU。（注：原文规格表仍沿用 2.8 英寸版的 480×320 IPS 屏条目，与 3.5 英寸的命名存在出入，请以厂商页面为准。）
微雪在 wiki 上提供出厂固件（据称基于 ESPBrookesia）、ESP-IDF 与 Arduino IDE 入门说明，以及包含小智 AI 语音助手的 AI 教程专区。
这是迄今所见 ESP32-C5 开发板上最大的屏幕。此前的方案包括 LILYGO T-DONGLE-C5（0.96 英寸无触控 OLED）、ESP32-C5-LCD-1.47（1.47 英寸非触控 LCD）与 LILYGO T-Display C5（1.9 英寸 IPS LCD，可选电容触控）。它们都是 SPI 屏，如果 3.5 英寸这款的 UI 过于复杂，渲染可能触及性能上限而变卡。若需要更高分辨率与更流畅 GUI 且要双频 Wi-Fi 6，需要考虑 ESP32-P4 + ESP32-C5 的方案（如 GUITION JC-ESP32P4-M3-DEV、Wireless Tag WT99P4C5-S1）并搭配 MIPI 屏。
售价方面，带/不带摄像头与电池的版本在 AliExpress 为 37.99–43.99 美元，亚马逊为 43.99–47.99 美元，微雪自营店为 31.99–35.99 美元。

Waveshare has launched the ESP32-C5-Touch-LCD-3.5, another ESP32-C5 development board with an integrated display, featuring a larger 3.5-inch color touch LCD, and optionally available with a BF3901 low-resolution (0.08MP) camera and/or a 500mAh battery.
The board also provides a speaker interface and built-in microphone for voice interaction, a six-axis IMU, temperature/humidity sensor, microSD card slot, and a 32-pin GPIO expansion header.
Key specifications
The wireless module is Espressif ESP32-C5-WROOM-1U-N32R8, with the SoC being the ESP32-C5HR8: a single-core 32-bit RISC-V processor up to 240MHz, plus a 40MHz low-power RISC-V core that serves as the main processor for power-sensitive scenarios; on-chip 384KB SRAM, 8MB PSRAM, 320KB ROM. Wireless supports dual-band (2.4GHz/5GHz) 802.11ax Wi-Fi 6 (with fallback to 802.11b/g/n), Bluetooth 5.0 LE, and 802.15.4 radio for Zigbee 3.0 and Thread 1.3. The module includes 32MB Flash and an IPEX antenna connector.
For the display, the official spec sheet lists a 262K-color IPS panel with 480×320 resolution and capacitive touch, using the ST7796 SPI display controller and FT6336 I2C touch controller (the article title, based on the actual board, says 3.5 inches). The optional camera is the BF3901 with 320×240 resolution. The audio chain includes an onboard MEMS microphone, a 2-pin speaker interface, the ES8311 low-power audio codec, and the NS4150B audio amplifier. USB is Type-C, used for power, flashing, and data. Sensors include the SHTC3 temperature/humidity sensor and the QMI8658 six-axis IMU. Expansion is via a 32-pin 2.54mm-pitch header, bringing out GPIO, UART, I2C, etc. Other features include power/reset/BOOT buttons, power and charging LEDs, and a PCF85063 RTC. Power can be supplied via USB-C 5V, or through a 2-pin connector for a 3.7V lithium battery, supported by the AXP2101 power management chip. Board dimensions are 95.11×63.67×14.10mm.
The specifications are quite close to the ESP32-C5-Touch-LCD-2.8 reported on in July, with the differences being a larger screen and higher resolution, an IPEX antenna (instead of a PCB antenna), an optional camera, a 32-pin GPIO header, and a more advanced AXP2101 PMU. (Note: the original spec sheet still lists the 480×320 IPS screen entry from the 2.8-inch version, which conflicts with the 3.5-inch naming; please refer to the manufacturer's page for accuracy.)
Waveshare provides factory firmware (reportedly based on ESPBrookesia), ESP-IDF and Arduino IDE getting started instructions, and an AI tutorial section containing the Xiaozhi AI voice assistant on its wiki.
This is the largest screen seen so far on an ESP32-C5 development board. Previous options include the LILYGO T-DONGLE-C5 (0.96-inch non-touch OLED), ESP32-C5-LCD-1.47 (1.47-inch non-touch LCD), and LILYGO T-Display C5 (1.9-inch IPS LCD with optional capacitive touch). They all use SPI screens; if the UI on this 3.5-inch model is too complex, rendering may hit performance limits and become laggy. For higher resolution and smoother GUI along with dual-band Wi-Fi 6, consider an ESP32-P4 + ESP32-C5 solution (such as the GUITION JC-ESP32P4-M3-DEV or Wireless Tag WT99P4C5-S1) paired with a MIPI screen.
Pricing: versions with or without the camera and battery are $37.99–43.99 on AliExpress, $43.99–47.99 on Amazon, and $31.99–35.99 from Waveshare's own store.
