== Supported Devices ==
The STM32X7 board supports several STM32X7 devices in the UFBGA-176 package. Various header jumpers can be set different positions to select appropriate power supply for the different power
domians of the device, and different measurements points. The following table summarizes examples of suitable devices:

= VCC-Int Supply === Several devices (F2, F4) have internal core voltage regulators. By default the CW308 board attempts to provide power for these pins, but the voltage may not be high enough to cause the internal regulator to disable itself. In this case you can use the VADJ regulator to ensure the internal regulator is disabled. See [[Targets with Internal Regulators]] for details. === Pin-outs across TQFP Devices === The following shows differences in pinouts between three groups of devices. The left-most is the STM32F051RB, which uses the same 3.3V VCORE as the STM32F1/F3. It has fewer VCC pins, so the I/O occupying that are VCC/GND pins on the STM32F1 (such as PF6/PF7) are tied to GND/VCC. The right-most part is the pinout of the STM32F2/F4. It has an internal regulator, where the VCAP pins are the output of this regulator (and input to the internal core logic).
Note for the devices with a 3. 3V VCORE, you should not mount decoupling capacitors C5/C6/C7/C8. You will still get some leakage with those capacitors mounted, but a stronger signal is present without them.
