Full feature list:

• Ability to communicate with RS232 and RS485 devices.
• High input voltage range (7-24VDC). This allows it to easily be used with existing industrial DC power supplies which are commonly 12-24VDC
• 4 x High current output capacity (10A per channel) MOSFET outputs, each output has it's own LED indicator for easy testing/troubleshooting/user notification. This allows for more precise control of loads such as PWM or driving extreme current relays in industrial settings.
• 2 x DRV8870 Motor Drivers (3.6A per motor driver or combined for motors up to 7A, can also be paired to drive a single stepper motor).
• 4 Analog Inputs with RC filter (0805 components for easy hand soldering to change filter values if needed).
• I2C broken out to D-Sub connector for additional sensors, add-on ADC modules or displays.
• I2C header with common OLED pinout in convenient location for ease of use as a user configurable data display.
• 2 Digital Inputs with hardware de-bouncing for limit switches, buttons, etc.
• 1 Digital Input with 4.7k pullup resistor for plug and play compatibility with Dallas One-Wire sensors (DS18B20 for example).
• CH340 USB-UART converter for easy programming without needing a programmer.
• Easily programmable in Arduino IDE or IDE of your choice.
• Robust connectors for reliable wiring (D-SUB 25 for inputs and coms, spring loaded connectors for outputs).
• Open Source hardware.
