This board was designed to trigger air solenoid valves on a pick and place machine. It has sixteen 60V 4A FETs driven by a PCA9685 PWM driver, which allows 12bit PWM at ~1500Hz.
If you do not want the screw cage connectors populated, or need higher voltages please let us know.
Description
Power input up to 35VDC with sixteen PWM driven N-FETs great for LEDs or solenoids.
Includes large prototyping area for custom circuits. The prototyping area includes break outs for I2C, SPI, 5 – ADC channels, 4 digital IOs, and a UART to make it easy to add custom sensors or ICs.
Additionally the ther are 6 digital IO pins on the green screw connectors for use, for example could be used for limit switches or anything you dream up.
The firmware is written using the Arduino IDE and has been designed such that it is easy to add new commands (G-Codes) to the source.

Drivers for the USB serial port are here. On some windows system since the driver is not signed you might need to do the same steps as outlined here to install the driver.
