Product Details

The EVAL-ADICUP360 is an Arduino and PMOD compatible form factor development board. The board uses CrossCore Embedded Studio, an open source Eclipse based Interactive Development Environment (IDE), which can be downloaded free of charge. The platform contains many hardware and software example projects, to make it easier for customers to prototype/create systems and solutions using the complete ecosystem provided.

The EVAL-ADICUP360 uses the ADuCM360 Arm Cortex-M3 processor as the main device on board. It has integrated dual 24-bit sigma delta converters on chip, which make it extremely flexible for both analog and digital application.

Features and Benefits

Two fully assembled and tested evaluation boards per kit
Full set of IC voltage options in each kit
3 samples of each IC voltage option packed in separate antistatic bags
Kit allows the user to quickly evaluate all IC voltage options
Only need to order one kit per product family

Product Details

This product has individual evaluations boards at specific voltages or with specific features as well as the RedyKit™. The RedyKit simplifies product evaluation by providing two assembled and tested evaluation boards, plus a full set of product (voltage) options for an IC regulator. All the IC options come sorted and stored in the kit with the Analog Devices part number clearly printed on each antistatic zip-top bag.

Simple device measurements such as line and load regulation, dropout, and ground current can be demonstrated with just a single voltage supply, a voltmeter, a current meter, and load resistors.
