This one's for when you're writing firmware or working close to the metal. It covers the usual embedded suspects: STM32 and ESP32 microcontrollers, RTOS setup with FreeRTOS or Zephyr, and peripheral drivers for I2C, SPI, and UART. Also handles Embedded Linux builds with Yocto and Buildroot, plus OTA updates. The skill claims expertise in safety-critical code and power optimization, which matters if you're doing anything production grade. With 169 installs and decent GitHub activity, it seems like people are actually using it for real embedded work, not just hobbyist projects.
