PCB version 2

Further development of modbus testing device to protect power input and extend functionality.

• Diode bridge
• Power metering (Volt + Amp)
• External analog ref for precision metering
• 1k res on LEDs for lower indication light
• MCU on board instead of Arduino
• POGO-pin for programming
• Check gnd connection modbus

For metering:

	Typ	Max	Unit
Power	5	20	Watt
Voltage	24	30	Volt
LP-filter cutoff	600	3000	Hz
