![]() The STM32Duino is noticeably smaller than the Uno, but longer than the Nano. In terms of physical size, Figure 1 shows a side by side comparison of a typical Uno, an STM32Duino and an Arduino Nano. ![]() One can easily notice that the Blue Pill is superior to the Arduino Uno in almost all aspects, except, in the mechanical compatibility of Arduino shields which are mostly designed for the Uno form factor. Table 1 provides a brief comparison between the most common STM32duino Blue Pill board and the typical Arduino Uno. Flashing the bootloader into the STM32duino.What you need to make the STM32duino Arduino compatible.While the mechanical incompatibility with Arduino shields cannot be fixed, it is possible to make it compatible with the Arduino development system. As received, the board will do neither of these. There are even more steps to be taken if it is to be made compatible with the normal way Arduino code is downloaded into the target module using the PC’s USB port. Second, there are some steps that have to be taken before it can run Arduino code. It’s just that these shields simply cannot be piggy-backed on the module. In most cases, it can still use those shields. First, it is not compatible with most Arduino shields due to differences in size and pinouts. If you are planning to use an Arduino for an early prototype of your product, then you should also consider the more powerful STM32duino development board.Ĭommonly referred to as the STM32 Blue Pill, this board has nearly all the capabilities of the Arduino module but with a cheaper price.įREE GUIDE: Introduction to Microcontrollers ![]()
