DRV8825 Stepper Motor Driver Module for Arduino. It allows you to control two drives, equipped with an XBee connector. DFRobot DRI0023

Audio Analyzer is a module with sound analyzer based on the MSGEQ7 system. It divides the sound into seven frequency bands, and then allows you to read the peak levels of each band. It allows you to measure the sound in the following frequencies: 63Hz, 160Hz, 400Hz, 1kHz, 2.5kHz, 6.25kHz and 16kHz. DFRobot DFR0126

Measurement module with RS485 interface. It has two voltage measurement inputs in the range of 0 to 5 V and 0 to 10 V and two current measurement inputs in the range of 0 to 20 mA. Supports the Modbus RTU protocol

The S9V11F5S6CMA switching step-up/step-down regulator efficiently produces a fixed 5 V (default) or 6 V (selectable) output whether it is higher or lower than the input voltage, which can range from 2 V to 16 V. (Note: minimum start-up voltage is 3 V, but it operates to 2 V after that.)
