How to assemble serial LCD kit

You can use this kit for displaying serial messages from Arduino. The kit is itself a programmable Arduino board that comes with ATmega328p. You just need to upload a serial LCD firmware to the ATmega328p chip of the kit and your kit is ready to display serial messages from Arduino. Read everything about the kit and serial LCD firmware from here.

Serial LCD KIT

Checkout the PCB:
Serial LCD Arduino
On the PCB, you can see that the names and polarity of components have been labeled. Therefore, there should not be any confusion while assembling the kit.

With the Serial LCD kit package you will get the following components:

Procedure for assembling the kit:

Step 1: Start with a 16Mhz crystal oscillator and 2pcs of 22pF capacitors. Fix them on the PCB.
Step 1- Fix 16Mhz oscillator and 2pcs of 22pF capacitor

Step 2: Fix a 10K resistor also.
Step 2- Fix a 10kOhm resistor.

Step 3: Fix 2pcs of 0.1uF capacitors.
