With the STM32 'Blue Pill' and an ST-LINK/V2, a .bin file can be
uploaded relatively easier than installing the tool chain for the
STM32 and getting it to work in the Arduino IDE. If I remember
correctly, the .bin file is cross platform? So, for example, if the
.bin file is created on a MS-Windows10 PC, it can be uploaded to the
STM32 board, using an ST-LINK/V2, with a Mac or Linux PC.

Mitch,
Yes, the STM32 can be difficult, especially if you are trying to get a bootloader working. I never got a bootloader to work well. Even if you do, the USB connectors on the Blue Pill are notoriously unreliable.
The fastest and easiest method to program a Blue Pill is with an inexpensive programmer called the ST-Link v2. Knockoffs are widely available on eBay and Amazon for about $6. I purchased mine on sale for less. It is well worth the money. See

Bruce,
I sure hope you consider adding ESP controllers to the GPS clock. I have spent two evenings trying to program STM32 blue pill boards, with limited success. One board I have managed to get programmed with a bootloader, one board says the bootloader upload was successful but it was't, and two boards refuse to be programmed. The ESP boards come with a bootloader, and it works!!!
Thanks for sharing your projects, they are very simple hardware wise with very sophisticated software.
