Namino Rosso, Arancio, and Bianco Industrial-grade ESP32 Development Boards

Italian startup Namino presents designers with a compact, Arduino-compatible development environment with an industrial twist for fast time to market in applications including industrial automation, smart home and home automation, IoT, and more. Thanks to a wide variety of connection interfaces, these boards simplify wiring by up to 83% during prototyping. For highest reliability, Namino’s boards are designed and built directly by Mect SRL, an Italian PLC and industrial automation manufacturer with more than 40 years of history.

Each of the Namino boards is built around an ESP32-S3-WROOM-1U-N4R8 module, which offers WiFi and Bluetooth connectivity using a shared antenna and features a powerful Xtensa dual-core 32-bit LX7 microprocessor running at up to 240 MHz. This is supported by 4 MB flash, 512 kB SRAM, and 8 MB PSRAM, with 16 kB SRAM in RTC (Rosso and Arancio only). Unlike many ESP32 boards, the Namino boards feature up to 8 digital inputs capable of handling 0-24 VDC and analogue inputs for 0-10 V.

The common features across these boards are an RS485 half-duplex interface, a DIN-rail shield interface, and programming and 5-V power supply via a USB-C interface – These boards can be programmed with Arduino IDE or VS Code IDE (PlatformIO). There are 3 Namino main boards available at present: Rosso, Arancio, and Bianco.

Bianco is the simplest of the three and comes in an Arduino UNO form factor. This board can be powered by 7-24 VDC input and offers Mikroe click board and Qwiic I2C interfaces. There is also a second USB-C port for direct ESP32 interfacing or UART programming options.

Rosso and Arancio come in a standard 503 form factor with and Arduino UNO shield interface on the top side and an industrial bottom side for connection to various interfaces that include:

  • Exchange contact relay output at 5 A
  • Analogue output at 0-10V / 0-20 mA
  • Analogue inputs at 0-20 mA
  • NTC Analogue inputs
  • High-current digital outputs
  • Thermocouple analogue inputs (Rosso only)
  • PT1000 analogue inputs (Rosso only)
  • Load cell inputs (Rosso only)

The Rosso and Arancio can be powered via Namino’s NERO boards for power via 100-250 VAC or 7-30 VDC. NERO also offers connection to a rechargeable 18650 lithium battery for power backup if desired.
