Update 1:

• Small optimizations to the casing
  • Added a small groove for lifting the lid
  • Added some space inside on the back for potential cables

Hello, here's a small project that I designed. I wanted to combine a small ESP32-C3 Super Mini with an LD2410C Radar/mmWave sensor and keep the whole thing as small and modular as possible. Later on, the project will be used with ESPHome and Home Assistant to control the lighting in individual rooms. I've specially designed holes for the pins of the LD2410C so that the sensor can be easily inserted there. The ESP32 is also simply inserted. If you like, you can use a dab of hot glue for fixation.
