Feature

●High Stability and Accuracy: Frequency generation has high stability and accuracy, simple but very effective
●2 Wires to Connect: Support I2C data transmission, only need 2 wires to connect the display or Si5351, very convenient
●Bar Graph Indicator: Also has a bar graph indicator strength and 20 Band presets, and can also be used as an RF or clock generator
●10khz to 220mhz Working Range: Working range is 10kHz to 220MHz, can be used with for Pro Mini. Use general 128x64 I2C for OLED for SSD1306 display and Si5351 module
●Self Made Equipment: This is a VFO(Variable Frequency Oscillator) project, which can be used for self made equipment, such as superheterodyne receiver, DCR, SDR or Ham QRP transceiver
