Mysensors RFM69W heater relay module

Description:

This is a Mysensors RFM69W actuator node for controlling a heater or other appliances using a relay

Key Features:

• AT25DF512C-SSHN-B SPI flash module for OTA
• ATSHA204A for signing
• MySensors ready(Atmega328p + RFM69W)
• HLK-PM01 as power supply

Work progress:

1. Test/verify the pcb board correctness(from both electrical and mechanical point of views) - DONE
2. Produce the initial PCB's using some external PCB manufacturer - DONE
3. Components assembly(soldering) - DONE
4. Create 3D printed plastic enclosure - DONE
5. Create MySensors sketch code - DONE
6. Verify the real board with running code - DONE
7. Verify OTA - DONE

Instructions:

1. Burn MCU fuses using avrdude like this: avrdude -cusbasp -pm328p -U lfuse:w:0xff:m -U hfuse:w:0xda:m (for external 8MHz crystal oscillator and bootloader)
2. Burn DualOptiboot bootloader
3. Upload the provided sketch with this project or roll your own(pay attention to set this preprocessor define: #define MY_OTA_FIRMWARE_FEATURE)

HW Revisions:

• 0.1 - initial hw design
• 0.2 - removed capacitor from reset switch as it can interfere with arduino serial bootloader if used
