Today I will show you how to Make Digital Voltmeter Ammeter Voltage Current Meter With JLCPCB

Step 1: Watch This VIDEO

This video show you how to make Current and Voltage Meter use JLCPCB Step by Step

Step 2: Make the Schematic and PCB

i use eagle software for make the Schematicand PCB

Step 3: Make the Gerber File and Upload to the JLCPCB.COM

Go to JLCPCB.COM for make PCB online

Only 2$ /10pcs for 2 layer PCB.

Upload your gerber files and fill in Shipping Adress then click PAY.

Step 4: Received Your PCB After 2 Day

10pcs on the box, very beatyfull and look great

Step 5: Order the Component
