- 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.
