Level Up, Professional Design achieved!
After the V4.1 hardware batch ran it’s course I quickly found the limitations of the previous designs and knew it was time to make the next big step, fully embedded hardware. This was going to be the most ambitious change yet as it required fully understanding every single bit needed to have my own professional circuitry design. 25 units were ordered for testing to see how it all worked out.
The biggest change by far was moving from pre-built arduino daughter boards to having the chipset and all required components embedded on my own board for faster assembly and unlocking the true potential of the hardware. The Voltage Regulator has had a major overhaul to a switching supply for almost no heat generation and much higher current capacity. Circuit protection and load distribution was greatly improved for a more robust design. A 3 Channel Relay Driver is included for fan control out of the box and a more versatile In/Out system for custom sensor reading.
