This powerful ARM® Cortex®-M0+ based Topoard is a drop-in replacement for the 32u4 or 1286 topboard of any existing Industruino PROTO or Industruino IND.I/O. It lets you upgrade your industrial controller to a whole new level of performance and functionality. The Arduino core and bootloader for this Topboard has undergone significant developments to get the most out of this wonderful MCU and to add remote ethernet sketch upload functionality.

The board support can be installed automatically from within the Arduino IDE using the boards manager.

The D21G Topboard brings Industruino industrial controls to a whole new level of flexibility:

1. More memory, more speed

2. 5V tolerant Arduino™ compatible Cortex®-M0+ based solution, keeping interfacing to older chips simple.

3. Special hybrid USB/Ethernet bootloader pre-installed allowing you to upload sketches remotely or to multiple difficult to access Industruinos. The TFTP bootloader is password protected and has CRC integrity checking.

4. Easy scheduling of tasks with a battery backed RTC that can trigger the MCU's interrupt at a specific programmed date/time.

5. Multiple SERCOM's - Dual SPI, Dual UART.

6. Faster graphics with less processing overhead due to dedicated hardware SPI port.
