Of our robot controllers, the Zauberzeug Robot Brain has the most digital I/O, with 24 DIO channels. It pairs an NVIDIA Jetson Orin Nano with a real-time ESP32-class controller and CAN/RS485/RS232/I/O modules. zauberzeug... +1zauberzeug.com ↗“io.dio_channel_count=24”zauberzeug.com ↗“combining an NVIDIA Jetson Orin Nano with a real-time ESP32-class controller and CAN/RS485/RS232/I/O modul”

Before you choose:
- How the 24 channels split: The Zauberzeug's 24 channels aren't broken down into inputs and outputs. You'd need to confirm the split for your sensors and relays. If you need a confirmed split, the BRAV-7131 has 8 digital inputs and 8 digital outputs. jhc-techno... +1jhc-technology.com ↗“io.digital_input_count=8”jhc-technology.com ↗“io.digital_output_count=8”
- Operating temperature: The Zauberzeug runs from 0 °C to 55 °C. The BRAV-7131 runs from -20 °C to 60 °C, but only with airflow. zauberzeug... +1zauberzeug.com ↗“thermal.max_operating_temp_c=55 °C, thermal.min_operating_temp_c=0 °C”jhc-technology.com ↗“thermal.operating_temp_condition=Requires airflow”
- Mounting: The Zauberzeug mounts on a plate, with DIN rail mounting as an option. zauberzeug...zauberzeug.com ↗“plate mounting, DIN rail (optional)”
What I couldn't confirm:
- Spot CORE I/O: It has digital I/O, but I couldn't find a channel count for it. bostondyna...bostondynamics.com ↗“io.digital_io=True”
- Other controllers: I couldn't find digital I/O details for the KUKA AI Extension Platform, Vention MachineMotion AI, farm-ng Amiga Brain (Xavier NX and Orin NX), LimX TRON 1 Voice Interaction Kit, Lambortech ECM400-Thor or Lambortech ECM410-Thor. That doesn't mean they have no digital I/O, so I can't rank them against the controllers above.
