Page 9: Power Supply Selection
3.3 V voltage regulator (U2) on the board. The 5 V pin of J4 or J7 can also be used as an input power source. The AT-START-F403A board must be powered by a 5 V power supply unit. -
Page 10: Programming And Debugging
The AT-Link-EZ PCB on the evaluation board can be separated from AT-START-F403A by bending over along the joint. In this case, AT-START-F403A can still be connected to the CN7 of AT-Link-EZ through CN2 (not mounted before shipping), or can be connected with another AT-Link to continue the programming and debugging on the AT32F403AVGT7. -
