How to test & prototype with STISO621
Choose a development kit to start testing the capabilities and features of STISO621:
To help developers get their design to market more quickly, the STISO621 evaluation board (EVALSTISO62XV1) allows a complete evaluation of STISO dual-channel digital isolators featuring high-speed communication and reduced distortion at high speeds.
A complete three-phase energy meter with low-cost shunt current sensors. Ready-to-use firmware implements a virtual com port communication to easily access the internal parameters to read metrology data, to modify the internal configuration for a high flexibility of the application, and to calibrate the board.
