Pros & Cons

Pros

  • ✓ LM317 three-terminal design gives continuously adjustable 1.25V-12V DC output
  • ✓ Runs straight off AC 110V wall input, no separate bench PSU needed
  • ✓ Doubles as signal generator, logic tester, and sensor alarm platform
  • ✓ Onboard buzzer supports soil-moisture and temperature alarm builds

Cons

  • ✗ 200 mA output ceiling rules out anything past small logic and sensor loads
  • ✗ Arrives as a component kit, so soldering and assembly are on you
  • ✗ 12V upper limit excludes common 15V and 24V rail projects
  • ✗ AC 110V input restricts use to North American mains
