ATmega2560 power — 12 DI, 12 DO, 10 relays, RS-485 and Ethernet.
NEXTuino PEAK is built around the ATmega2560 — the same processor as the Arduino Mega 2560. With 12 protected digital inputs, 12 transistor outputs, 10 relay outputs, integrated RS-485 Modbus RTU and Ethernet, the PEAK handles complex automation tasks that require more I/O and real network connectivity.

Multi-axis sequencing, interlock logic and process control for mid-size production machines.
Ethernet port enables direct connection to SCADA and HMI systems over TCP/IP Modbus.
RS-485 Modbus RTU connects to variable speed drives, servo amplifiers and soft starters.
10 analog-capable inputs for pressure, temperature and flow transmitters.
Submetering and load shedding via Modbus energy meters on RS-485 bus.
Chiller plant sequencing, AHU control and BMS integration via Modbus and Ethernet.
Yes. The PEAK is based on ATmega2560 — identical to the Arduino Mega 2560. Any library or sketch written for the Mega works on the PEAK without modification.
The PEAK includes an on-board RS-485 transceiver. Use the standard Modbus library to communicate with up to 32 devices on a single RS-485 bus at up to 115 200 baud.
The FLEX adds 6 extra digital inputs (18 total), 0–10 V analog I/O channels, and operates on 24 V only. The standard PEAK supports both 12 V and 24 V and has RS-485 Modbus.
Yes. The PEAK includes a W5100-based Ethernet port for TCP/IP communication — SCADA integration, remote monitoring and web-based control.
