PAC5523AEVK1 Evaluation Kit
Qorvo's PAC5523AEVK1 evaluation kit is a complete hardware solution enabling users to evaluate the PAC5523A device, but also develop motor control applications revolving around the powerful and versatile 150MHz Arm® Cortex® -M4F based MCU. This evaluation kit is a motor controller and driver evaluation PCB, that uses PAC5523A Power Application Controller®.
To aid in evaluation and application development the PAC5523AEVK1 offers access to all of the PAC5523A device's signals by means of a series of female header connectors.
Supporting Evaluation Tools
The ET-UARTSWD adapter is the preferred adapter for evaluation of PAC devices/firmware and combines a USB to UART adapter with SWD debugger connector adaptation into a single board with isolation. The ET-UARTISO-1 adapter provides only the USB to UART adapter with isolation for Qorvo application GUI communications.
ET-UARTSWD
The ET-UARTSWD isolated communications and debugging interface unifies two modules into one. Previously, interfacing a PC Computer to any of Qorvo's PAC5xxx Evaluation Modules required one module to enable UART based serial communications and a second module to allow for in-system debugging and FLASH memory programing.
