The Power Supply USB UART Module for CANADUINO® Permanent Breadboards is the perfect accessory for your CANADUINO® permanent breadboards.

It is piggyback-soldered onto your breadboard and provides 5V and 3.3V to your CANADUINO® Permanent Breadboard.

The integrated USB Type-C connector enables programming and monitoring using the onboard CH340 USB UART chip.

• Input voltage 5V, 2.1A from standard USB charger.


• Output voltage 5V, 2A (max.), electronically protected.


• Output voltage 3.3V, 1A/0.6A (max./continuously), electronically protected.


• USB Type-C port for power supply and serial communication.


• CH340K USB-UART for programming and serial communication.


• Selectable RX/TX logic level (3.3/5V) and 50bps to 2Mbps transfer speed.


• DTR signal output can be used as reset signal for connected MCUs.

To select the voltage, close the solder jumper for 3.3V or 5V on each of the 2 power rails.

The same applies to RX/TX logic level selection - just close the jumper on the 3.3V or 5V side.

The 2 LEDs indicating 3.3V and 5V can be activated by closing the LED jumper. Otherwise, the LEDs will stay turned off.

Add a USB-C cable to your order.
