Product Features

The HW-ET LIVE Tiny88 (16.0Mhz) microcontroller development board is similar to the Arduino series development board, but with higher cost-effectiveness, smaller size, and more powerful functions. Due to its ability to use the well-known Arduino IDE, HW-696 ATTiny88 is a development board that can quickly get started with DIY electronic products, and can effectively replace other development boards that are too large in size and too complex to assemble.

When HW-696 ATTiny88 leaves the factory, except for the included needle set that needs to be welded by the user, all other components have been fully assembled, and welding is also convenient and simple

Product Funtion

Installation and testing steps of development board based on Arduino

1. Download the installation package: In the Arduino IDE, in the "File" and "Preferences" fields, type in the "Add in Manager URL" box:

https://raw.githubusercontent.com/MHEtLive/arduino-boards-index/master/package mhetlive index.json

2. Go to the "Tools" menu, then select the "Boards" submenu - choose "Board Manager", and then select "Contribution" from the Type drop-down menu: choose the "MH-ET LIVE Boards" software package, and click the "Install" button;

3. The USB driver can also be downloaded from the accompanying files, and the connection is as follows:

https://github.com/MHEtLive/MHEtLiveArduino/releases/download/1.0.0/2.0a4.rar

4. When downloading the program, simply plug in the data cable and do not connect the module. When prompted to insert the module after compilation, plug it in and wait for the automatic download to complete. This development board does not have a port option, and the specific selection is shown in the following figure

5. You can choose the built-in example of Arduino IDE: Select the development board MH-ET LIVETiny88 from the toolbar, open the program in File>>Examples>>Basic>>Blink, change the port 13 in the program to port 0, compile and download it into the tiny88 development board according to the above method. The LED lights on the board can be seen flashing at the frequency specified by the program.
