🔹 What's Included

1 × 0.36" 2-Wire Self-Powered LED Voltmeter

🔹 Pro Tip

💡 The 2-wire version is the simplest possible voltmeter — positive and negative connections only. For measuring voltages below 4.5 V (e.g. LiPo cells), use the 3-wire version with a separate power supply instead. Panel cutout: 28 × 13 mm.

⚠️ Note: Always ensure proper heat dissipation and correct voltage configuration before powering connected devices.
