This motor driver module is a special PPM signal motor controller for Aero modelling remote control. It is designed by DFRobot and it can be controlled by RC transmitter. The driver can convert PPM signal to the motor speed and direction control signal. There are two signal receiving channels (CH1, CH2) and two motor channels (M1, M2) on the board. Each signal input channel uses a standard 50-Hz PPM signal with a duty cycle of 5% to 10%. When the rocker returns to the middle, the motor stops rotating, waggling the rocker up and down (or left and right), and the motor rotates forward or backward.

DFRobot Gravity 12-Bit I2C DAC is a small and easy-to-use 12-bit digital-to-analog converter with EEPROM. It can accurately convert the digital value to corresponding analog voltage signal, which is useful in may creative projects and automatic control systems. Although an analog voltage signal can be generated by PWM with traditional controllers such as Arduino and Raspberry Pi, such signal is ROUGH and NOT ACCURATE. To obtain a steady and nice analog voltage signal, the DAC is the best candidate. In addition to be applied in automatic control systems, the DAC module can be used to serve as a function generator to generate sine wave, triangular wave and even arbitrary waveform (we provide a library to generate low frequency sin and triangular wave with just a few parameters).

DFRobot I2C ADS1115 16-bit ADC module can accurately collect and convert analog signals. Through this ADC module, Raspberry Pi can easily use a wide range of Gravity series analog sensors to measure various signals, and perceive this world. Raspberry Pi is a common master control board which is powerful in its functions, but the I/O pins of Raspberry Pi can read digital signals only, what's more, only through an external analog-to-digital conversion (ADC) module can it read signals of analog sensor or device, it is not convenient to use. DFRobot I2C ADS1115 16-bit ADC module is specially designed for Raspberry Pi and Gravity series analog sensors, which greatly reduces the difficulty of using the Gravity series analog sensors, plug and play, no welding, very convenient. The number of Gravity series sensors is large and its wide variety can meet the needs of various sensors of the Raspberry Pi.

3.7V lithium batteries are commonly used in many projects. However, the remaining power and voltage of the lithium battery are highly nonlinear. We can only roughly judge whether the battery is full or almost empty according to its voltage. The Gravity I2C 3.7V Lithium Battery Fuel Gauge employs Gravity I2C interface, ultra-low operating current, and real-time tracking of the relative state of charge (SOC) of the battery through Maxim's patented algorithm, eliminating the need for full-to-empty relearning and offset accumulation errors. Plug and play to accurately measure the voltage and remaining power of the battery. The module also features as a low battery power alert interrupt function. When the battery power falls below specified threshold, the ALR pin generates a falling pulse to trigger the external interrupt of the controller.
