The Micro SD TF Card Module is SPI interface via file system driver, microcontroller system to complete the MicroSD card reading and writing functions.
The 2SA-1266, 2SA1266-Y is 50V 150mA 400mW PNP Bipolar Transistor, manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor.
The Hall Effect Sensor Module can be used to detect the presence of an magnetic field. If there is an magnetic field present, it will report a high level signal.
The TIP32C is a base island technology NPN power transistor in TO-220 plastic package with better performances than the industry standard TIP32C that make this device suitable for audio, power linear and switching applications. The PNP type is TIP31C.
