AM-138 ADS1015 12-Bit Precision Analog-to-Digital Converter I2C Breakout Board
US$17.86
The following module is an Analog-to-Digital module that complements any system lacking ADC conversion. It provides a 12-bit precision conversion for up to 4 different multiplexed single ended analog inputs or 2 differential analog inputs. It can be setup in either single-shot (powers down after one sample conversion) or continuous mode (continuously converts samples). This board can run on 2VDC to 5.5VDC and it doesn’t need a Voltage reference to be supplied to it as it uses an internal reference. The configurable sample rate of the chip can reach as high as 3300 SPS and as low as 128 SPS.

AM-137 4 Way I2C Bi-Directional Logic Level Converter 5VDC/3.3VDC for Microcontrollers and Modules
US$3.07
This module works very well with any I2C projects you are working on. It will convert any 5VDC logic level to a 3.3VDC logic level and any 3.3VDC logic level to a 5VDC logic level. The four level conversion modules on the board allow it to do so for up to four different data channels. It is very practical for any system composed of incompatible I2C modules as it enables them to be compatible and communicate without a problem. It is also very easy to setup due to the pins being identifiable on the board. Just make sure to connect your High level reference to “HV” and to connect your Low level reference to “LV” (they both have their respective ground plains).

DFR0457 Gravity: MOSFET Power Controller
US$6.93
The MOSFET power controller is a module which can drive a large current device with limited current GPIO. It works as a MOSFET relay or MOSFET driver. When you give it a digital high-level signal (3.3~10V), MOSFET turns on, vice versa. Compare to the relay module, MOSFET power controller is compatible with Arduino, Raspberry Pi, Lattepanda and other Microcontroller, supports 3.3~10V logic power control. The VIN port supports 5~36V; 0~20A power input, if the current is over 10A, we recommend an external heat sink. And MOSFET supports quick ON-OFF switch, the switching frequency arrives 1KHz. That is a good point for robot control.
