Description
Embedded PLC with WiFi – Arduino Opta WiFi AFX00002
The Arduino Opta WiFi AFX00002 is a compact programmable logic controller that brings industrial automation into a small form factor. Built on the Arduino Opta platform, it supports ladder logic, Structured Text, and function block programming, allowing users to design sophisticated control sequences without a bulky PLC chassis. With native Wi‑Fi (IEEE 802.11b/g/n) and Modbus‑RTU/TCP capabilities, the module integrates seamlessly into existing networked environments, enabling remote monitoring, real‑time diagnostics, and OTA firmware updates.
Powered by a 5 V supply, the AFX00002 offers a rugged 4‑digit digital I/O set (2 inputs, 2 outputs), a 12‑bit single‑ended ADC for sensor readings, and an optional UART/RS‑485 interface for legacy field‑bus connectivity. Its ultra‑low‑profile PCB measures 50 × 30 mm, making it ideal for tight real‑time assemblies in laboratory instruments, home‑automation HMI panels, or embedded control systems.
- Key Spec 1: 4 digital I/O (2 inputs, 2 outputs), 12‑bit ADC
- Key Spec 2: Wi‑Fi 802.11b/g/n, WPA2‑PSK security, Modbus‑RTU/TCP support
- Key Spec 3: 5 V (DC) power supply, 1 mA standby current
- Common Use Case: Small‑scale automation tasks such as greenhouse climate control, DIY robotics, and remote‑sensing stations
