UDacq10 firmware provides built-in capability for configurable digital inputs/outputs, analog-to-digital conversion, R/C servo outputs, and serial peripheral interface (SPI). The firmware is provided in the form of a non-modifiable binary hex load file.  Firmware source code option is also available (Hi-Tech C). 

UDacq10 includes schematic, PCB layout (ExpressPCB), hex load file for PIC microcontroller programming (requires device programmer), and parts list.  Contains driver and API library for host software development.  Also includes sample PC host software (VC++ 6.0) plus demo source. The API library (UsbDacApi) greatly simplifies host software development by encapsulating complex USB operations, giving you easy access to your device. 

UDacq10 is ideal for a number of applications including data acquisition, robotics, industrial control, education, research and more!
