Tzduino

Tzduino is a development board based on the Arduino UNO board design. It has a TM1650-driven four-digit digital tube and voltage regulation chip, and some unnecessary components for my experiments have been subtracted. The board uses USBtypeC for power supply and uploading programs. If the VIN pin is used for power supply, a voltage of 5V must be input. A vacant header in the lower left corner of the original UNO is used for adjustable voltage output in Tzduino. Rotating the potentiometer can adjust VOUT between 2.25V-18.5V. VOUT is connected to the A7 pin of Atmega328P through a resistor divider ( The original version has not been exported), which can be monitored by Arduino and displayed through the digital tube. When the voltage adjustment module is not used, the digital tube can also provide data display function. In addition, adding a switch connected to the internal No. 2 interrupt makes the control more flexible. Since I do not need the DC interface power supply in a large number of experiments, I removed the DC interface and 5V voltage stabilization related devices. This allows the VIN interface to only input a voltage of 5V, but it will not affect most experiments. Related class libraries are being improved...
