![]() ![]() Īfter the driver for CP2102 was installed, a few sample Arduino sketches such as "Blink" and "Fade" were uploaded to make sure the chip was still functioning before designing the board in Eagle PCB. The Arduino Mega is a microcontroller board based on the ATmega1280 (datasheet). 0.1uF capacitor x 1 between module's DTR pin and RESET (chip pin 30). Arduino Mega 2560 projects list:The Purpose of designing Arduino Mega 2560 is to create bigger and more ambitious projects that comes in mind.It was first released in 2010 and has since become a popular choice among makers, hobbyists, students, and professionals in the fields of engineering, robotics, and electronics. CP2102 USB to UART TTL Module (one that has a DTR pin), with the connections: The Arduino Mega 2560 Rev3 is a microcontroller board based on the ATmega2560.If you use the pin as a digital input, you can enable the internal pull-up resistor for that pin. The digital section (page 67) shows the switchable pull ups. The Atmega 2560 datasheet ADC section (page 268) makes no mention of pull ups on the analog inputs. 16MHz ceramic resonator connected between chip pins 33 and 34, with resonator's ground pin connected to chip's GND. A pull up makes no sense on an analog input.LED x 1 and 1k current limiting resistor x 1 connected between D/13 (chip pin 26) and GND, this is same as the Arduino Mega "L" LED, to be us as indicator to test prototype. ![]() 10k pull-up resistor x 1 connected between RESET (chip pin 30) and VCC/AVCC.0.1uF bypass capacitor x 3, connected in parallel to 3 of the VCC/AVCC and GND pairs (chip pins ).The board provides 76 digital inputs/outputs (13 with PWM capability), 14 analog inputs and 2 analog outputs (DAC) all easily accessible via pin headers. Connect all VCC/AVCC (chip pins 10, 31, 61, 80, 100) together and GND (chip pins 11, 32, 62, 81, 99) together. The Arduino GIGA R1 WiFi brings the power of the STM32H7 to the Mega form factor, being the rst Mega board to include onboard Wi-Fi® and Bluetooth® connectivity.ATmega2560 chip from an Arduino Mega2560 clone (functional chip and bootloader) removed with a hot-air gun, soldered on to a TQFP100 breakout PCB.A prototype board was made as proof of concept, the components, placements, and connections are: A pull up makes no sense on an analog input. ![]()
