PRODUCT DESCRIPTION:

The GroundStudio Jade N1 development board is an improved version of the classic Nano board, featuring a USB Type-C adapter (upgraded from microUSB). It uses the HT42B534-2 chip for USB 2.0 to Serial (UART) conversion.

The Jade Nano development board is small, complete, and fully compatible with the baseboard, based on the ATmega328P. It offers the same connectivity and specifications as the UNO board in a smaller form factor.

The board is equipped with 20 digital I/O pins, which can be programmed using the Arduino IDE. The Jade N1 provides various communication options for connecting to a computer, another board, or other microcontrollers. The ATmega328 offers TTL UART (5V) serial communication available on digital pins 0 (Rx) and 1 (Tx). The HT42B534-2 chip on the board facilitates this serial communication via USB.

The Arduino software includes a serial monitor that allows simple text-based communication with the ATmega328P. The RTX LED will blink when data is transmitted through the HT42B534-2 chip and the USB connection to the computer (but not for serial communication on pins 0 and 1). The SoftwareSerial library enables serial communication on any of the Nano’s digital pins. The ATmega328P also supports I2C and SPI communication.

* For Windows 7, 8, or 8.1, drivers can be found in the Downloads section.

Example Connection in Arduino IDE:

For this example, you will need the following:

1x GroundStudio Jade N1 Development Board || Reference LTAYNO_AAA

Step 1 - Download Arduino IDE

Arduino IDE

Before connecting the board, start by downloading Arduino IDE 1.8.x from the link above, based on your preferences and operating system.

Step 2 - Connect the Development Board to the Computer

After the initial connection via a USB-C cable, the computer will attempt to find a compatible driver. In this case, it will connect directly to Windows using the HT42B534-2 chip, as its drivers will be installed automatically.

Step 3 - Configure Arduino IDE

To select the board, go to the "Tools" menu, then click on the "Board" button and make sure "Arduino Nano" is selected.

After selecting the board, a new section "Processor" will appear in the Tools menu. Here, you need to select the "ATmega328P" option.

Next, you need to tell the Arduino IDE which serial port on your computer the Jade N1 is connected to. To do this, go to "Tools" again and select the COM port of the Jade Nano.

If you have multiple ports and are unsure which one belongs to the Jade N1, disconnect it for a moment and check the "Device Manager" under the "Ports" section to see which one disappears.

After selecting the COM port and the board, you can upload the "Blink" code from the menu: File -> Examples -> 01.Basics -> Blink.
