Possibly this version was written for the beta test version of the MKR1000, which had a different pinout than the final version of the board?

• XMegaForArduino project: https://github.com/XMegaForArduino/IDE/raw/master/package_XMegaForArduino_index.json

  • Github project: http://github.com/XMegaForArduino
  • Support for several XMEGA processors (some may require compiler patches), more to come
  • Basic 'pins_arduino.h' files for 'standard' layouts, described in the file
  • Intended to be the basis for your own custom XMEGA-based board
  • Supports dedicated pins for hardware serial flow control
  • Implements a low-current 'wait' state for delay and wait for interrupt
  • bootloaders for 'arduino' and 'wiring' protocol.
  • USB support 'under development' (for ATxmega128A1U, others)
  • Provides new libraries for SPI, SD, 2-wire so you can start using these right away
  • Includes patch files for compilers and tools (source patch), and instructions on how to modify earlier IDE versions
  • Leverages XMEGA's internal 32 MHz clock in the startup code (no external crystal or resonator required)
  • Advanced interrupt handling support (basically ANY pin can be an interrupt).
  • Advanced pin settings include pull up, pull down, on both input and output
  • Project is still in a 'beta' state, but is fully functional for nearly all practical uses, and as 'Arduino compatible' as could be made possible.

• HelTec cubecell: https://resource.heltec.cn/download/package_CubeCell_index.json

  • Github project: https://github.com/HelTecAutomation/CubeCell-Arduino
  • Based on an ultra low power design, attains 3.5uA in deep sleep mode, even with the RTC clock running;
  • LoRa signal output put power range 0~22(±1) dBm;
  • Low-cost despite its current state of the art technology;
  • Integrated encryption algorithm protects your investment by rendering cloned firmware inoperative;
  • Based on proven technology - the new ASR650x, is a combination of the PSoC4000 and SX1262 into a single chip, reducing the overall size to something smaller than the competition;
  • Solar panel support;
  • LoRaWAN protocol support;
  • AT command support;
  • In the LoRaWAN relevant examples, have a reasonable timeline planning.
