The module is based on the KA2284 system. It is used to measure the input signal with the 5 LEDs, which are gradually included depending on the value of the measured voltage. It can measure voltage AC or DC (selected using jumpers). Sensitivity is adjustable with a potentiometer. Works with voltages from 3.5 V to 12 V.
A module designed for reading the Li-Pol 3.7 V battery charge level in real-time. It is also equipped with alarm function when the battery level is low, or when battery power drops below a certain threshold, helps to estimate the battery life. In projects that run on solar power it helps to register the rate of change of battery power even within a month.
Kit quick installation fee is designed to allow the user the current measurement of the power input. The kit can be used, among other things, to check the stability of the power supply under various loads, safety switches, checking battery life. Using tile you can use the power supply voltage up to 30 V at currents up to 4 A.
Module from the Grove is equipped with a dual H bridge L298Ncontrolled ATmege 8L. The system allows you to adjust the direction of rotation of motors with a maximum current consumption up to 1 A and a voltage of 15 V. the kit includes a cable adapted to overlay Seeedstudio Base Shield v2.0.
