The Teensy 2.0 has two dedicated UART serial pins located on PORT D, pins 2 and 3. Common grounds must always be used for communication systems to allow for reliable signal transfer. To wire the system, connect a common ground between the CP210x module and the Teensy 2.0. For this example the CP210x module will be used to power the Teensy 2.0 at 5V after programming.
Both outputs are only rated of low currents (less than 100mA) but it can be very useful for powering a small system from a USB port. Unique to this PCB implementation of the CP2102 is both a 5V and 3.3V output. This example will detail the wiring for a Teensy 2.0 microcontroller. Wiring: The CP210c module can be connected either a 5V or 3.3V logic level UART serial port.CP2102 with other USB-UART adapter circuit works similar to the PC through the driver's USB port into a virtual COM port in order to achieve the purpose of expansion. tiny26 Microcontroller Board (tiny26.1)ĬP2102 its high integration, built-in USB2.0 full-speed function controller, USB transceiver, crystal oscillator, EEPROM, and asynchronous serial data bus (UART), supports full-featured modem signals, without any external USB device.
