Canique MK3e - Microcontroller with LoRa support
The MK3e (e stands for efficient) is almost identical to the MK2 but has a more sophisticated power circuitry and supports a different set of RFM69 radio modules.
The MK3e can be obtained with RFM69HCW/RFM95/RFM96 and with or without additional 4 Mbit flash memory.
It can be powered by a voltage of ~4.1V-12V (via the voltage regulator, input "VIN") or with 3.3V via the input "3.3".
Please note that the MK3e usually draws ~2uA more power than the MK2 but is more flexible. While the MK2 draws extensive current at certain scenarios, the MK3e has the ability to shut down its voltage regulator automatically when powered via the 3.3V pin and thus manages to stay below 10uA in typical sleep scenarios.

Where to buy
The MK3e is not produced anymore.
Important usage notes
- The 6 pin FTDI port on the Canique MK3e supports up to 12V on the power supply since the power is routed through the voltage regulator.
- Always attach an antenna before sending data. Otherwise you may damage the radio module.
- Don't connect a voltage source to "VIN" and "3.3" at the same time. Otherwise the regulated voltage of "VIN" will be connected to the voltage from the "3.3" port.
Compatibility
The MK3e generally is compatible to any other Atmega328P based board. For details about compatibility please consult the
exact pin assignments (LED, RFM69 slave select etc.).
The MK3e is especially compatible to Moteinos since it shares the same pin assignments. That means that software that has been written for the Moteino can be reused as is for the MK3e - without any changes.
