I created Rock Board in 2017.
- The Rock Board can be powered from 12 to 24V DC. It is protected against reverse polarity. Filtered power supply.
- There are 3 half-duplex serials that can be configured in RS485 or RS422.
- For each serial it is possible to insert the bias resistors and the relative bus start/end resistors.
- 48 outputs arranged on 2 levels. For each output there is a led that indicates the status.
- 16 opto-isolated inputs that can be configured using the INPUT MODE jumpers. The inputs can be configured with on/off or powered.
- 2 rotary switches
- Ethernet + W5500
- RTC + supercap
- Alphanumeric I2C display 2 lines x 16 characters
- EEPROM
- Unique MAC Address ID
- Unique 128bit ID
- ATMEGA2560 Arduino chip (with USB programming and micro SD card connector) and/or AriaG25 Embedded Linux module (with 6 buttons)
- Optional DIN rail enclosure
