This module is a member of the IoTextra series, which serves as a fundamental building block of our ecosystem and embodies the Make Things Happy Philosophy. It is engineered to bridge the gap between rapid prototyping and industrial-grade reliability.

Hardware Synergy: The module is compatible with both IoTsmart and IoTbase series.

Software Power: This hardware compatibility unlocks the full potential of the IoTflow platform. It enables you to:

  • Create custom Node-RED nodes effortlessly.
  • Integrate via MQTT with third-party global platforms like Blynk.
  • Scale your project from a single node to a complex industrial network.

Key Specifications

  • ADC: two 16-bit ADS1115 (ΔΣ), 4 differential channels total
  • Measurement speed: up to 860 samples per second
  • Voltage ranges: 0–0.5V, 0–5V, 0–10V, ±0.5V, ±5V, ±10V
  • Current ranges: 0–20mA, 4–20mA, ±20mA, 0–40mA
  • Gain-setting resistor: jumper-selectable 24.95kΩ or 49.9kΩ per channel
  • Precision grade: STD (±0.1% resistors, C0G/NP0 capacitors) or Lite (±0.5–1% resistors, X7R capacitors) — same circuit, different passive-component tolerance
  • I²C interface: 100kHz, 400kHz, 3.4MHz; connection via Qwiic or HOST-P12 pins 11/12
  • I²C addressing: DIP-switch selectable per ADC pair (channels 1–2 and 3–4)
  • Protection: reverse polarity, ESD (TVS on Qwiic)
  • Connectors: HOST (12-pin), Qwiic × 2
  • Size: 47 × 56 mm, with mounting holes for base-module or Raspberry Pi installation

Operation Modes

🔌 Standalone
Analog readings are available via the I²C bus, through the HOST connector or the Qwiic connectors. The ADC ALERT/RDY signals are routed to the HOST connector.
🧠 Smart
An IoTsmart module is inserted vertically into the HOST connector. Analog data and the 5V module supply are provided through HOST, powered from the IoTsmart module.
🏗 Mezzanine
The module is installed into an IoTbase carrier board. Analog data and the 5V module supply are provided through HOST.

Applications

🏭 Industrial Process Monitoring
Measures 4-20mA transmitter outputs from pressure, temperature, and flow sensors, or reads 0-10V analog signals directly — no external signal conditioning needed thanks to the onboard PGA and precision voltage reference.
🤖 Robotics & Lab Automation
Captures voltage and current outputs from bench power supplies, sensor calibration rigs, and test equipment across four independent differential channels — 16-bit resolution and selectable gain suit precision lab measurements.
🌱 Smart Farming
Reads 4-20mA soil moisture, pH, or EC sensors alongside 0-10V feedback from irrigation valve actuators — differential inputs reject common-mode noise from long field wiring runs.
🏠 Smart Home & Consumer Electronics
Monitors battery charger voltage/current curves, appliance sensor feedback, or infotainment system analog inputs — configurable per-channel voltage or current range covers most consumer sensor interfaces.
