Datasheets for items I have used in projects for quick reference.
Clock Generators
Si5351 – I2C, three-channel programmable source generator. Default address is 0x60.
Displays
SSD1306 – 128 x 64 Dot Matrix OLED/PLED Segment/Common Driver with Controller
Note: Displays with this controller are frequently paired with 3.3V regulator (Package marking: 662K, SOT-23, Vin(max) 8V, 300mA) to allow 5V operation with SSD1306. VLOGIC is still 0V to 3.3V.
