DFR0513 PPM 2x3A DC Motor Driver
US$26.25
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.

DFR0552 Gravity: I2C 12-Bit DAC Module
US$8.75
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).
