The STM32F103C8T6 has characteristics that surpass the traditional Arduinos type Atmel
We go from a speed of execution 16 MHz to 72 MHz and 8-bit to 32-bit. The module is supplied in a soldered version.

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

It has an Atmega2560 chip running at 16Mhz with a factory loaded bootloader with 54 digital input / output pins (from which 14 can be used as PWM outputs) and 16 analog inputs, 4 UART (hardware serial ports). The board includes a USB connector, an ICSP port, a reset button and some status LEDs. Atmega16U2 programmed as a USB-to-serial converter. Simply connect it to a computer with a USB cable or power with a power adapter and DC connector.
