Azoteq Evaluation Kits feature a modular design. Designers can connect one of the supplied IC modules into the main board, or wire into a prototype for rapid prototyping. Azoteq Evaluation Kits can be used in one of 2 modes: Direct mode: battery or USB powered, output on LEDs, or Data Streaming Mode to a graphical user interface. OTP bits can be programmed on the kit. The main board can be interfaced to any personal computer with the optional
Azoteq Configuration Tool and can be used with the data streaming
dongle, making the adjustments by means of the USBProg
