Last Update:
This USB control module handles multiple digital inputs (switches and device binary states), digital outputs (binary controls and status LEDs) and analog inputs All controls and sensors are handled at the app level.
The IOC-M-2 module is 54x23mm and is intended to be soldered on to or plugged into another circuit board (2×20 0.10″ x 0.60″ pitch) that implements the sensors, controls and relevent connectors.

Product Description
Decaf IOC-M-2 package includes
- the 72 MHz Cortex-M3 controller board with firmware already installed, plus USB cable.
- Virtual COM port usb cable (Red/Green/White/Black = 5V/GND/Tx/Rx)
- PiXCL 20 for app creation (Windows 10), via download.
The controller board firmware provides your prototype board with support for:
- 8 digital outputs (active H) i.e. equivalent to turning a switch ON.
- 2 digital control outputs (active L) i.e. for devices with CS (ChipSelect) L requirements.
- 8 digital inputs (active H) i.e. when a switch or equivalent is ON.
- 2 analog inputs (0-3v3) for your sensors.
- SPI devices with NSS and external CS pins. This allows multiple SPI devices to part of your project.
- COM port output (virtual COM port cable included)
- Real Time Clock (RTC) e.g. for time stamping data events. An external VBAT (3v3 such as a button battery) can be supplied to keep the RTC running if needed.

There’s an application note on adding an SPI based 160×128 LCD to the IOC-M-2.
How about a real development board for the IOC-M-2?
