There are 2 PCB designs: type "F" and type "G". Both untested.

Type "F" features:

• only SMD componens,
• internal power source,
• 10 output channels,
• 4 input channels,
• 5 relays: 1 * 16A + 4 * 7A,
• buzzer,
• EEV support,
• 16 bit i2c ADC: on board,
• i2c devices: allowed,
• ds18b20 on one lane.

Type "G" features:

• no SMD components,
• external, board-placed power source,
• 5 output channels,
• 4 input channels,
• 5 relays: 2 * 16A + 3 * 7A,
• buzzer,
• EEV support,
• 16 bit i2c ADC: off board,
• i2c devices: allowed,
• ds18b20 on one lane.
