Summary
HT-HC33 is a development board with integrated camera, based on the ESP32-S3 MCU and Wi-Fi HaLow module.It is designed for long-range, high-speed wireless communication. With support for transmission distances of over 1 km and speeds of up to 32 Mbps, it is ideal for IoT applications that require reliable, high-performance connectivity.
The module features a low power consumption design with excellent signal penetration, ensuring robust performance even in challenging environments. The integrated camera has a 200-pixel wide-angle, which supports advanced image processing functions such as auto exposure control, auto gain control, image scaling, and image compression.
Main Features
- The MCU is the ESP32-S3, and the Wi-Fi HaLow module is HT-HC01.
- Long transmission range, up to over 1~2km.
- Fast transmission speed, with a maximum of 32 Mbps.
- Low power consumption design with strong penetration.
- Integrated 300-pixel wide-angle camera.
- Supports the Arduino development environment.
- Integrated SD card slot for easy local deployment and data storage.
- Integrated CP2102 USB-to-serial chip, convenient for program downloading and debugging information printing.
- Type-C USB interface with a complete voltage regulator, ESD protection, short circuit protection, RF shielding, and other protection measures.
- Integrated Wi-Fi, Bluetooth, and Wi-Fi HaLow three network connections, with onboard 2.4 GHz patch antenna for Wi-Fi and Bluetooth, and reserved IPEX (U.FL) interface for Wi-Fi HaLow.
- Onboard SH1.25-2 battery interface, integrated lithium battery management system (charging and discharging management, overcharge protection, battery power detection, USB/battery power automatic switching).

FAQ
Each IO pin is preconfigured with IO_MUX functionality, which means you can use any GPIO as I2C or SPI pins. You just need to define these pins in your code. However, it’s important to note that once a pin is used, it may affect other functions associated with that pin.
include Wi-Fi, Bluetooth, and Wi-Fi HaLow, with an onboard 2.4 GHz patch antenna for Wi-Fi and Bluetooth, as well as a reserved IPEX (U.FL) interface.
The HC33 model has a different camera and adds a 2.4G IPEX connector.
