PRODUCT DESCRIPTION

Improvements

The Jade M1 development board is an improved version of the classic Mega2560 board. It features a USB Type-C adapter (upgraded from USB Type B), HT42B534-2 for USB 2.0 to Serial (UART) conversion, and a 3V3 I2C adapter compatible with STEMMA QT or QWIIC for quick I2C connections to compatible devices.

The Jade M1 development board is compatible with sensors and other modules operating at 5V (connected to pins) or 3V3 (connected to the 3V3 I²C adapter).

For UART communication with devices using a 3.3V logic level, a logic level converter module is required.

The position of the RESET button has been improved. Placed on the side, the button can be pressed even when used with a shield.

Memory

The ATmega2560 chip has 256KB of flash memory for storing code (8KB is used by the bootloader), 8KB of SRAM, and 4KB of EEPROM (accessible with the EEPROM library).

Interrupt

The digital pins on the GroundStudio Jade M1 development board that can be used as interrupts are: 2, 3, 18, 19, 20, and 21.

Since pins 20 and 21 are externally connected to pullup resistors for I2C communication, they cannot be used as interrupts when used for I2C communication.


Pin Functions:

LED The onboard LED is controlled by digital pin 13. When the pin is HIGH, the LED is on; when LOW, it is off.
VIN Input voltage to the board when using an external power source (as opposed to 5V from the USB connection or other regulated power sources). You can provide power through this pin, or access the input voltage if providing power via the DC power jack.
5V The 5V stabilized power source generated by the onboard regulator. The board can be powered through the DC power jack (7-20V), USB connector (5V), or the VIN pin (7-20V). Note: Supplying power through the 5V or 3.3V pins bypasses the regulator and may damage the board. Maximum output current is 500mA.
3V3 The 3.3V stabilized power source generated by the onboard regulator. Maximum output current is 500mA.
GND Ground pins.
IOREF This pin provides the reference voltage at which the microcontroller operates. A properly configured shield can read the IOREF pin voltage and select the appropriate power source, or enable level shifters to work with 5V or 3.3V.
Reset Typically used to add a reset button to shields, blocking the onboard button.
SPI 50 (MISO), 51 (MOSI), 52 (SCK), 53 (SS). These pins support SPI communication using the SPI library.
PWM 0 to 13. Provide 8-bit PWM output using the analogWrite() function.
TWI 20 (SDA) and 21 (SCL). Use TWI communication with the Wire library.
AREF Reference voltage for analog inputs. Used with analogReference().
The Mega2560 has 16 analog inputs, each providing 10 bits of resolution (i.e., 1024 different values). By default, they measure from ground to 5V, but their range can be changed using the AREF pin and the analogReference() function.

* No additional driver installation required on any updated operating system (unlike other modules on the market like CH340, FTDI, etc.).

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

* Compatible with R3 shields.

* Pins 20 and 21 are directly connected to the 3V3 I²C logic converter and have pullups enabled, which may cause incompatibility with certain shields.

Example of Connecting Arduino IDE:

To complete this example, you will need the following:

1x Jade M1 Development Board

1x USB-C Cable


Step 1 - Download Arduino IDE

Before connecting the board, downloadArduino IDE, based on your preferences and operating system.

Step 2 - Connect Jade M1 to the computer

After the initial connection via USB-C cable, the computer will attempt to find a compatible driver. It will directly connect to Windows using the HT42B534-2 chip since drivers for this will install automatically.

Step 3 - Configure Arduino IDE.

To select the board, go to the "Tools" menu, click the board button, and ensure Arduino Mega is selected.

Next, select which of your computer's serial ports the Jade M1 development board is connected to. For this, go to "Tools," hover over Serial Port, and select the COM port for the Jade M1.

If multiple ports are available and you are unsure which one is the Jade M1, disconnect it for a moment and check the menu to see which port disappears.

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