Wireless Stick is a perfect enterprise-class IoT platform. It integrates WiFi, LoRa, and Bluetooth network development boards to connect any of your IoT devices easily and quickly.

The main control chip is a 32-bit dual-core ESP32 chip, which integrates WiFi and Bluetooth functions. The main processor can run the user application completely freely, with an additional ULP coprocessor, which can monitor GPIOs, ADC channels and control most of them. Internal peripheral

The product is small in appearance, has powerful computing functions, supports Arduino, rich interface and other product features, users can program the product through standard library and simple development language, and quickly complete solution verification and product development.

Development environment installation

We have posted the latest development environment installation method at this address: http://www.heltec.cn/wifi_kit_install/

The following driversCP210X version driver installation method:

For Mac OS, Ubuntu, Windows 7 and above, the driver is automatically installed. If it is not installed automatically or an error is indicated, please download and install the latest driver from the Silicon Labs website:CP210X version driver download address

(After many tests, we found that the driver of the CP210x series chip version is the most stable. This version is highly recommended:download link

Take the Windows operating system as an example. If the driver is installed normally, you can see similar information in Device Manager – Port:
