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

There are other flavors of the devices with the same pinout, which makes them compatible with this target board. E.g.
=== VCC-Int Supply =Power 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 The device must 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 STM32F051RBsupplied 3v3, which uses the same 3.3V VCORE as the STM32F1/F3. It has fewer VCC pins, so since the device's I/O occupying that are VCC/GND pins on the STM32F1 (such as PF6/PF7) are tied to GND/VCClogic uses 3v3. 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 logic core logic)uses 1v2.
[[File:power_diffstm32=== Internal regulators ===The device contains an internal regulator regulating the input voltage down to 1v2. This can however be bypassed by supplying a slightly higher voltage to the target board's 1v2 pin.png|800px]]
Note for == Measuring power consumption ===The target board contains headers which lets the devices with a 3hacker select where to measure.3V VCORE, you should not mount It is possible to select to measure power on the 3v3 input and the 1v2 input/decoupling capacitors C5/C6/C7/C8. You will still get some leakage with those capacitors mounted, but a stronger signal is present without them.
