3x RS-485 Shield with 4809 and 5V/24V supply


I soon will have a shield which has the following specs:

  • 3x RS-485 interface
  • ATMEGA 4809 slave cpu doing the RS485
  • SPI comms between RockPi E and 4809
  • UPDI download of ATMEGA 4809
  • ATMEGA 4809 software may be written via Arduino IDE
  • DC/DC Converter for optional supply from 24V DC

Typical applications

  • Modbus sniff, record, mangle, split

Might this be of use for anybody here?
Are there any suggestions what shall be added to this shield?

Kind Greetings,
