![]() initialize digital pin LED_BUILTIN as an output. the setup function runs once when you press reset or power the board This example code is in the public domain. Model, check the Technical Specs of your board at: If you want to know what pin the on-board LED is connected to on your Arduino The correct LED pin independent of which board is used. It is attached to digital pin 13, on MKR1000 on pin 6. Most Arduinos have an on-board LED you can control. Turns an LED on for one second, then off for one second, repeatedly. The block diagram to understand the internal circuitry of the TTL CP2102 UART module is as shown:Ĭonnect the pins of CP2102 UART Module with Arduino Mini Pro according to the table provided down below: Arduino Pro Mini The module requires no external pull-up resistors.CP2102 is compatible with existing drivers and COM ports. ![]() It supports the XOn/XOff handshake mechanism.For the power control, the module is integrated with Suspend pins.The module is embedded with two voltage regulator circuits i.e.The CP2102 has a 12Mbps full-speed USB Specification 2.0 compliant.ICP2102 UART module is integrated with a high-speed transceiver.Some of the additional features of the USB to UART module are described below: Package Type: 28-pin QFN package (RoHS-compliant).When it changes its state, a hardware interrupt is produced. It indicates when a good carrier is received from the modem.Īctive low Ring Indicator input pin. It shows that the terminal is ready for data transfer.Īctive low Data Carrier Detect input pin. It shows that it is ready to accept the data.Īctive low Data Terminal Ready output pin. It supports the Xon/Xoff handshake mechanism.Īctive low Ready-to-Send output pin It supports the Xon/Xoff handshake mechanism.Īctive low Data Set Ready input pin. The pin configuration in tabular are detailed as below: Pin NameĪctive low Clear-to-Send input pin. The pinout of the compact CP2I02 UART module is as shown: Pin Configuration CP2102 ComponentsĬP2102 USB to UART Bridge module consists of CP2102 chip, Modem Interface Signal port, Control port, UART data transmission plus control ports, power port, and built-in TX & RX LEDs. The tutorial is a guide to the pinout, specifications, features, working, and applications. However, it requires drivers to start the serial communication. The device is embedded with two voltage regulators and matching pull-up resistors.CP2102 is compatible with Windows/Linux/Mac OS-X/OS-9 and existing COM ports. Moreover, it contains a PROM of 1024 bytes and a 48 MHz internal oscillator. The module supports handshaking and also processes the command requests made by the USB host to control the activities of the asynchronous serial UART port. CP2102 possesses a high-performance, inbuilt transceiver for serial data along with suspend/resume signals for the energy control of the chip and external circuitry also. It is a single CP2102 chip USB to UART Bridge with 12Mbps USB full speed. The maximum current for the 5V and 3.3V outputs are 800mA each.CP2102 UART module is the upgraded version of RS-232 Communicator introduced by Silicon Labs. (The voltage regulator allows up to 18V input, however, we do not recommend exceeding 9V since the higher voltage can lead to overheating and damage the device.) The onboard voltage regulator operates in a range of 6V to 9V DC. The board can be powered directly through the Micro USB connector, or via the corresponding contacts on the board (Vin and GND). It has a Micro-USB connector (universally used by most phones, including Android smartphones) to connect the microcontroller to the computer via the CH340 USB-UART adapter (the CH340 driver may need to be installed on your computer).Ĭonnectivity to the computer is provided through the common micro USB connector. ![]() It uses the original ATmega2560-16AU chip, a 16 MHz high-quality quartz resonator, and the CH340G USB-UART interface. The Mega Pro Mini functionalities are identical to the Arduino Mega2560. It has a compact form factor of 54mm x 38mm (2.1" x 1.5") and is an excellent solution for developing embedded and stand-alone projects based on the ATmega2560. This MEGA2560 Pro Mini board is a low cost, miniature version of the popular Mega 2560 microcontroller and is compatible with the Arduino Mega 2560. ![]()
