SparkFun Qwiic Ultrasonic Distance Sensor - HC-SR04 8-Bit Ultra-Low Power STM8L051 MCU Core
You may be familiar with the classic HC-SR04 distance sensor, it is great for providing non-contact distance readings from 2cm to 400cm. The SparkFun Qwiic Ultrasonic Distance Sensor improves on the classic by adding a pair of Qwiic connectors to it, so now you can communicate over I2C and daisy chain any other Qwiic product of your choosing. If you prefer to bypass the Qwiic connector and I2C you can also access the VCC, Trigger, Echo, and Ground pins broken out on the edge of the board. Please be aware that this ultrasonic sensor comes uncalibrated and you will need to manipulate the raw output for your specific application. The 8-bit ultra-low power STM8 MCU Core provides increased processing power (up to 16 MIPS at 16 MHz) while maintaining the advantages of a CISC architecture with improved code density, a 24-bit linear addressing space and an optimized architecture for low power operations. It also features embedded data EEPROM and low power, low-voltage, single-supply program Flash memory. The device incorporates an extensive range of enhanced I/Os and peripherals, a 12-bit ADC, a real-time clock, two 16-bit timers, one 8-bit timer, as well as standard communication interfaces such as an SPI, an I2C interface, and one USART. Ideally, power will be supplied via the Qwiic connectors on either side of the board. Alternatively, power can be supplied through the pins along the bottom side of the board labeled 3V3 and GND.The input voltage range should be between 1.8-3.6V.
