Choosing a beginner microcontroller depends on various factors, from ease of use to the project's complexity. The ESP32 or Raspberry Pico are fantastic for their user-friendly nature, reasonable features, and cost-effectiveness. For space-constrained projects, the ATTiny is a go-to with its simplicity and low cost, perfect for basic electronic setups. When diving into more intricate software, the Raspberry Pi Zero 2 shines with its versatility and improved availability. Mixing and matching these, like a PiZero with a Pico, or an ESP32 paired with an ATTiny, can offer pragmatic solutions. However, for more robust power, the Raspberry CM4 stands out, although it's more board than a microcontroller. It's crucial to consider longevity and support when choosing, ensuring the design lasts and is easier to revisit in the future
