Design or Project

In some designs or projects, a small and powerful master control is usually required. The Arduino Nano is designed to solve this problem. It reduces the size while taking into account the resources and functions on the board. While using you can choose to directly connect the sensor to the controller pin, or plug it into the PCB board of your own design.

Key Features Compatible with Arduino uno, although the pin resources are slightly less than the Dreamer Nano, but if you haven't used Leonardo, it is recommended. The controller is Leonardo, which is more suitable for the design of interaction with the computer. The UNO is made into Nano size, with integrated Bluetooth function, which is suitable for the design that needs to interact with Bluetooth. Compared with Nano, Pro Mini has a smaller size. It removes the onboard downloader. If you want to download a program, you need an external FTDI downloader. which is ideal for products that do not require replacement code when the design is complete, such as some handheld game consoles. The parameters are basically the same as the Pro Mini 5V version, except that the working voltage of this one is 3.3V. If the sensor in your system works at 3.3V, you can choose this one.

FAQ

Driver installation problem

F1.How to install the driver?

Q1.There is a corresponding driver installation tutorial in the wiki of each product. It is recommended to download and install the corresponding driver according to the description in the wiki. In addition, you can watch this tutorial directly:Mindplus Install Driver

Program download problem

F1.I have installed the driver, but the device manager still cannot find the port and cannot download the program?

Q1.Open the device manager, plug and unplug the board to observe whether the device manager interface will refresh. If the device manager page does not refresh, it means that the data cable used has no data transmission function. Give it a try with another data cable.

F2.There is no problem with the driver, and the corresponding port can be selected when downloading the program code, but an error will be reported when downloading the program code?

Q2.Please confirm that the code has no errors; confirm the board model is selected correctly; whether the serial port is occupied (the D0 and D1 ports of the Arduino series controller cannot be connected to anything when downloading the program code); when using the Bluetooth controller, make sure that Bluetooth is disconnected when downloading the program code.

Expansion Shield problem

F1.What is the use of the expansion board?

Q1.The expansion board is divided into IO expansion board and functionality expansion board. The IO expansion board expands the pins of the controller, making it more convenient to use with sensors. All Gravity series sensors in the DF mall can be easily plugged into the expansion board; the function expansion board adds corresponding functions. For example, the Arduino motor drive expansion board adds the ability to drive the motor for the Arduino controller.

F2.Do I have to use an expansion board when using the controller?

Q2.We recommend using the expansion board according to the needs and functions. Using the expansion board will greatly reduce the wiring difficulty when using the sensors. If you do not use the expansion board, please confirm you can solve the sensor wiring problem by yourself. Especially when using Micro:bit or controlling the sensor, it must be used with the control board.
