39 - Multifunction Digital VFO - Part 1: Hardware

Nick M0NTV builds an Arduino-based, Si5351-powered multifunction digital VFO. This video (Part 1) tackles the hardware: the next video will examine the software. HARDWARE USED ---------------------------- 1) DIYmalls 1.8" TFT LCD Display Screen Module 4-Wire SPI Interface ST7735S 128x160 w/SD Card Slot for Arduino UNO Mega2560: https://www.amazon.co.uk/DIYmalls-Dis... 2) KY-040 Rotary Encoder. Like these: https://www.amazon.co.uk/KY-040-Encod... 3) Si5351 Module on Breakout Board. Like these: https://www.amazon.co.uk/AITRIP-Si535... 4) Arduino Nano. Like these: https://www.amazon.co.uk/Arduino-ATme... I've listed these items from one global supplier - clearly other sources are available! I hope this gives you an idea about what I've actually used myself in the construction.
