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:
