Crowtail – Bluetooth-compatible Low Energy Module is a small BLE + EDR communication module intended for wireless data transmission in IoT and automation projects. It enables fast serial-interface connection with mobile devices or computers.

The ACS72981 current sensor module uses the Hall effect to accurately and safely measure AC and DC current, providing electrical isolation of the current path. With a wideband analog output (up to 250 kHz) and low conduction resistance (0.2 mΩ), it minimizes energy loss and offers a fast response time of less than 2 µs. Pololu 5271

Efficient step-down converter that reduces the input voltage from up to 45 V to a regulated output voltage range from 1.4 to 7 V, offering high efficiency and a maximum continuous current of 3.8 A. It has built-in protection against reverse polarity, overload and short circuit, and the spread spectrum function reduces EMI interference. The module is equipped with an additional potentiometer for adjusting the cut-off voltage. Pololu 4852

An efficient step-down converter that steps down the input voltage from as low as 45 V to a regulated output voltage range of 1.4 to 7 V, offering high efficiency and a maximum continuous current of 3.8 A. It has built-in reverse polarity, overload and short circuit protection, and the spread spectrum function reduces EMI interference. Pololu 4853
