You can find me on the "Nintendo Alarmo Hacking" Discord server if you have any questions or need help.
Pinout for ST-LINK / SWD.
Install this custom firmware on the Nintendo Alarmo STM32 flash if you want an easy way to install and launch homebrew, install custom themes, and much more. Before you can install this firmware you need to obtain the secret Alarmo AES key/IV and remove the STM32 MCU protections. This process is very dangerous and can permanently brick the STM32 MCU. You will need an ST-LINK debug adapter and some soldering will be necessary. Read the manual for more information.
Lua binaries for Windows, compatible with Nintendo Alarmo .lua files.
If you want to compile it yourself, grab the source code and set the "LUA_32BITS" define to "1" in the "luaconf.h" file.
