It uses its own design with general products and uses pcb as well as the choice component. Why is it a little more expensive than a similar product in general? Yes because it 's better quality than a similar product that' s commonly marketed. The highly affordable stm32 black pill development boards allow anyone to try out new ideas and to quickly create prototypes with stm32f103 core arm cortex-m3. Software for arduino idea If board already have the stm32duino bootloader, can programming with arduino ide, via usb connection to pc. Programming with arduino idea the board is easy the community had done a lot of work to create a support package for it. You do need a recent version of the arduino idea. - steps: 1.Download and installl the official arduino idea. Versions 1.6.10 till 1.8.5 have been reported to work fine. 2.If you already have the arduino ide installl and it 's a newer version, see the boards manager package method of installlation. Note: This method is deprecated and not supported in forum! 3.Run arduino ide, and open the menu tools - > boards - > boards manager. Installl the "arduino sam boards" package (including the arduino due) from the list of available boards. This installls compiler support for arm cortex-m3. 4.Download a zip file containing the arduino stm32 files from here. 5.Unzip the content of the zip file, and place the arduino_stm32 folder to arduino sketches folder / hardware / arduino_stm32. Create the hardware folder if it does not exist yet. Example how the path should look like: C: / users / < user > / documents / arduino / hardware / arduino_stm32 #Kingcel_d
