MOD-115 PL2303 USB to UART Communication Conversion Board
US$6.15
This USB module allows users to interface any 5v or 3.3v microcontroller to communicate with their desktop/laptop environment. Simply insert the USB into any available port on your computer, install the drivers for the chip to be detected and connect four wires to your target device. Your target device can be a ATmega328p that is 3.3v or a 5v Arduino Pro mini. The board has five pins on the other side and on the back the description for each pin. Simply connect RX and TX to your target device with ground and determine what voltage the board operates at. You can use 5v or 3.3v depending on which pin you choose.

AM-136 MP3 Audio in AD4 Format Playback Module for 3.3v Arduino
US$7.69
This product allows for direct playback of MP3 Audio files encoded in AD4 file format stored on a MicroSD/TF card. The module features an output that can drive an 8ohm speaker using the SPK+ and SPK+ pins. Alternatively, you can drive a single ended amplifier directly from the DAC output via the AUDIO-L pin. This unit also has some few dedicated pins to allow microcontroller signals to control playback features such as play and pause, track forward/backwards and volume up/down. You could also use a two wire serial interface to select the track and send playback controls.

AM-123 Red + Green dual color LED Module for 5v Microcontrollers
US$2.76
This module is a simple board that has a dual color LED onboard. The two colors that are available are green and red. When voltage is applied to one extremity and ground is from the center it will light up RED. When the user changes to the other extremity but keeps the center as ground it will change to Green. This neat little device makes it easier for users to program states to inform users the condition of the battery charge without having to integrate two individual LEDs.

SF-ROLLPAW Standard Gripper Kit Rollpaw for Robotic Arm Rollarm DIY Robot Arduino Uno
US$30.79
The Rollpaw kit is a simple solution for projects that need small grippers. It is driven by two 9g SunFounder servos: one to control the jaws to open and close, and the other to control the rotating of the paw. When the jaws is fully stretched, the maximum distance is 60mm, which means it can grip an object with a 60-mm diameter. The joints of the two jaws are all connected with self-locking nuts, so that they would not fall off easily during the rotating and keep the paw "safe and sound". The Rollpaw is easy to assemble and use with the code provided.
