You can buy a lot of development board with popular IC ESP32 which supports Bluetooth and WiFi connections. Pan Tulabadi shared a few pictures of his development board which is called NODE32pico which includes ESP32 PICO D4 (two low-power Xtensa 32-bit LX6 microprocessors, 448KB ROM, 4MB Flash, 520KB SRAM).

This very small development board contains except of ESP32 PICO D4 also ceramic antenna, pads for u.FL connector for external antenna, temperature and humidity sensor HTS221TR by STMicroelectronics with very ...

If you are designer of power supplies or you only want to design own power supply, check this article about switching regulators.
The switching regulator has a lot of advantages. But, if you choose some not good switching regulator or your PCB design will not be good, you can make significant source of EM emissions.

STMicroelectronics acquired Atollic in December 2017. After that, a lot of people speculated that Pro version could be free for everyone.
Atollic released a new version of IDE - 9.0.0 and the speculation is confirmed. The latest version and following are without license for STM32.
The new name of IDE is TrueSTUDIO for STM32. If you are using CubeMX, the process how to generate the code is the same, choose option SW4STM32 in the setting of project.

The IDE TrueSTUDIO for STM32 is available for Linux and Windows.
