To become familiar with the world of microcontrollers it is necessary to have a development board (also known as a kit), which generally allows you to start working on it easily. Fortunately, the ST provides a wide portfolio of development boards. In this guide, we will describe and use the Nucleo board. The Nucleo has been introduced a few years ago and its line is divided into three main groups: Nucleo-32; Nucleo-64; Nucleo-144. Nucleo-32 Development Board The number of pins available, so the package, gives the name to the board: Nucleo-32 uses an LQFP-32 package; Nucleo-64 and LQFP-64; Nucleo-144 an LQFP-144. The Nucleo-64 was the first line introduced and counts 16 different boards. The Nucleo boards have interesting advantages compared to the Discovery. First, is the cheaper cost, you ...
