DS3231 is a 16-pin I2C clock module with temperature sensor and EEPROM. Operates between 2.3-5.5V with 0.84-3.0µA battery consumption. Features two programmable alarms with interrupt functionality. Includes leap year function and temperature sensor with +/-3°C accuracy
Cross-platform Arduino library for RDA5807 and RDA7088 FM radio devices. Supports I2C protocol for easy device control. Contains over 80 functions for FM reception and tuning. Works with Arduino boards, ATtiny, STM32, ESP32 and more
Serial communication transmits data bit by bit over time. UART is a simple 8-bit protocol using single data line. RS-232 converts 5V UART to higher voltage for long-distance communication
Library enables Arduino IDE interaction with ST's VL53L0X time-of-flight sensor. Supports I²C communication between Arduino and VL53L0X board. Compatible with Arduino IDE versions 1.6.x and later
Library for BH1750FVI digital light sensor breakout boards. Uses I2C communication with two pins. Configuration must be done in user code. Supports six measurement modes with different precision levels
New Arduino user struggles to control FM1216 tuner module. Sketch outputs only 3 bytes of data despite SCL-Line showing 3 bursts. External pullup resistors unnecessary as Arduino pulls them to +5V
