Set of Pro Mini Atmega328 5V 16M + USB-UART Adapter CP2102 for Arduino 

Pro mni has an Atmega328P chip running at 16Mhz with a factory-loaded bootloader. It does not include pins so we can solder only the pins we need. 

Ideal for connecting TTL RS232 devices to your PC through the USB port. 

Huskylens PRO is an easy-to-use AI camera and vision sensor. DFrobot Huskylens (SEN0336) is equipped with multiple functions, such as face recognition, object tracking, object recognition, line tracking, colour recognition and label recognition (QR code).

This little board is simply a I2C board to Qwiic converter. It pretty much enables any device with I2C connectors to work with Qwiic system. It has two Qwiic ports - both of them served with the same I2C bus. You simply stick the board on your I2C board and get additional two Qwiic ports. It is as easy as it sounds
