Keyestudio UNO R3 Board for Arduino - Black + Yellow

Keyestudio UNO R3 Board for Arduino - Black + Yellow. Keyestudio UNO R3 BOARD Overview: Keyestudio Uno R3 is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC…


he Uno Rev3 is a microcontroller board based on the ATmega328 (datasheet).



The low-power Atmel 8-bit AVR RISC-based microcontroller featuring 32KB self-programming flash program memory, 2.5KB SRAM, 1KB EEPROM, USB 2.0 full-speed/low speed device, 12-channel 10-bit A/D-converter, and JTAG interface for on-chip-debug.

Examination of the Arduino millis() Function

Examination of the Arduino millis() Function -- this can be gleaned by crossreferencing the Arduino core code with the ATMega328p datasheet, but is very useful in this concise article

ATMega328 - TQFP - Taking Arduino to the next level. These don't come with the arduino bootloader so you have to pull the ICSP pins out to a header and use an AVR programmer with the Arduino IDE to burn the firmware over ICSP.
