Either of the USB ports can be used for programming the board, though it is recommended to use the Programming port due to the way the erasing of the chip is handled :
The 101 is open-source hardware! You can build your own board using the following files:
CAD FILES IN .ZIP SCHEMATICS IN .PDFThe 101 can be programmed with the Arduino Software (IDE). Select "Arduino/Genuino 101" from the Tools > Board menu. For details, see the reference and tutorials. The board comes preprogrammed with an RTOS that handles USB connection and allows you to upload new code without the use of an external hardware programmer. It communicates using the DFU protocol (reference).
The 101 has some features in common with both UNO (connectors, available peripherals) and Zero (32bit microcontroller, 3.3V IO) but the low power Intel microcontroller, on-board BLE and motion sensors make it unique.
Please check out the compatibility guide here.
Your 101 board might receive an update of the firmware from time to time. The Arduino Software (IDE) will incorporate the latest Firmware and an automated update procedure from the "Burn Bootloader" menu item. For people interested in compiling their own firmware, the source code and full details on how to use it are made available on the dedicated Intel's Download Page.
The 101 board can be powered via the USB connection or with an external power supply. The power source is selected automatically. External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The adapter can be connected by plugging a 2.1mm center-positive plug into the board's power jack. Leads from a battery can be inserted in the GND and Vin pin headers of the POWER connector.
The power pins are as follows:The Intel Curie module memory is shared between the two microcontrollers, so your sketch can use 196 kB out of 384 kB (flash memory) and 24 kB out of 80 kB (SRAM)
Each of the 20 general purpose I/O pins on the 101 can be used for digital input or digital output using pinMode(), digitalWrite(), and digitalRead() functions. Pins that can be used for PWM output are: 3, 5, 6, 9 using analogWrite() function. All pins operate at 3.3 volts and can be used as interrupt source. See the attachInterrupt() function for details. Each pin can source or sink a maximum of 20 mA.
In addition, some pins have specialized functions:The Arduino M0 can be powered via the micro USB connection or with an external power supply. The power source is selected automatically. External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The adapter can be connected to the board by plugging a 2.1mm center-positive plug into the board's power jack. Leads from a battery can be inserted in the Gnd and Vin pin headers of the POWER connector. The board will automatically detect which power sources are available and choose which one to use according to the following priority:
External power is required when the 500mA through the USB connector is not enough to power a connected USB device in a USB host application. The power pins are as follows:
The ATSAMD21G18 has 256 KB of flash program memory (with 4 KB used for the bootloader). The bootloader is factory pre burnt by Atmel and is stored in a dedicated ROM memory. The bootloader is protected using the NVM fuse. It also carries 32 KB of SRAM.
Each of the 14 digital i/o pins on the M0 can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 3.3 volts. 7mA as maximum DC current for I/O pins and an internal pull-up resistor (disconnected by default) of 20-60 kOhms. In addition, some pins have specialized functions:
The Arduino M0 has a number of facilities for communicating with a computer, with another Arduino or other microcontrollers, and with different devices like phones, tablets, cameras and so on. The SAMD21 provides one hardware UART and three hardware USARTs for 3.3V serial communication. The Arduino software includes a serial monitor allowing simple textual data to be sent to and from the board. The RX and TX LEDs on the board will flash when data is being transmitted via the ATSAMD21G18chip and USB connection to the computer (but not for serial communication on pins 0 and 1). The Native USB port is connected to the SAMD21. It allows for serial (CDC) communication over USB. This provides a serial connection to the Serial Monitor or other applications on your computer. The SAMD21 also supports TWI and SPI communication. The Arduino software includes a Wire library to simplify use of the TWI bus. For SPI communication, you can use the SPI library.
The Arduino M0 can be programmed with the Arduino software (download). If you use Linux-based OS follow the guide Arduino IDE on Linux-based OS. Uploading sketches to the SAMD21 is different from how it works with the AVR microcontrollers found in other Arduino boards: the flash memory needs to be erased before being re-programmed. Upload operation is managed by a dedicated ROM area on the SAMD21. USB port: To use this port, select "Arduino M0 (Native USB Port)" as your board in the Arduino IDE. The Native USB port is connected directly to the SAMD21. Connect the M0 Native USB port (the one closest to the reset button) to your computer. Opening and closing the Native port at 1200bps triggers a 'soft erase' procedure: the flash memory is erased and the board is restarted with the boot loader. Opening and closing the native port at a different baudrate will not reset the SAMD21.
The M0 has a resettable polyfuse that protects your computer's USB ports from shorts and overcurrent. Although most computers provide their own internal protection, the fuse provides an extra layer of protection. If more than 500 mA flows through to the USB port, the fuse will automatically break the connection until the short or overload is removed.
The maximum length and width of the M0 PCB are 2.7 and 2.1 inches respectively, with the USB connector and power jack extending beyond the former dimension. Four screw holes allow the board to be attached to a surface or case. Note that the distance between digital pins 7 and 8 is 160 mil (0.16"), not an even multiple of the 100 mil spacing of the other pins.
