Full PEAK connectivity and I/O — without the Arduino pin headers.
The NEXTuino PEAK CORE provides the same processing power, I/O count, RS-485 Modbus RTU and Ethernet as the standard PEAK, but without Arduino pin headers. Designed for OEM panel builders who need high-channel-count control in a compact, production-ready module.

Yes. The MCU and I/O mapping are identical. Firmware written for the PEAK runs on the CORE without changes.
The CORE suits OEM installations where Arduino shield expansion is not needed. No headers means reduced board height and lower BOM cost for high-volume panel builds.
Yes. Both RS-485 Modbus RTU and Ethernet (W5100) are included, accessible via terminal blocks.
