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.)

The S9V11MACMA switching step-up/step-down regulator efficiently produces a finely adjustable output between 2.5 V and 9 V whether it is higher or lower than the input voltage, which can range from 3 V to 16 V. The regulator also has a precision-adjustable low-voltage cutoff with hysteresis that can be used to prevent battery over-discharge.

The FS5106R is a standard-sized servo that has been built by FEETECH specifically for continuous rotation, making it an easy way to get your robot moving. It features two ball bearings on the output shaft for reduced friction, and it offers easy access to the rest-point adjustment potentiometer. 

This add-on board makes it easy to control two high-power DC motors with a Raspberry Pi. Its twin discrete MOSFET H-bridges support a wide 6.5 V to 30 Voperating range and are efficient enough to deliver a continuous 18 A without a heat sink. The drivers offer basic current limiting functionality, and they accept ultrasonic PWM frequencies for quieter operation. 

The 32L4R9IDISCOVERY kit is a complete demonstration and development platform for STMicroelectronics Arm® Cortex^®-M4 core-based STM32L4R9AI microcontroller.

Recorder v3.0 is a module that allows you to record and play sounds. The module was based on the ISD9160FI system, it also has a FLASH memory with a capacity of 2 MB, which allows for recording up to 83 seconds long. The set contains a small loudspeaker on which recorded sounds can be played. Seeed studio 107020029
