Ask your administrator if you think this is wrong. ====== Arduino Leonardo ====== A microcontroller board based around the ATmega 32u4 chip. Clocked at 16 MHz, it includes 32 KB of program flash (4 KB used by the bootloader), 2.5 KB of SRAM, and 1 KB of EEPROM. {{ ::leonardo-pinout.png?400 |}} Its footprint and pinout are mostly the same as the [[arduino uno|Uno]]. However, it features two independent UART serial streams (one USB and one on pins 0/1) and five user interrupt pins (0, 1, 2, 3, 7). The PWM pins are also shifted around slightly. <WRAP center round tip 60%> Pins 2 and 3 are SDA and SCL for I2C! </WRAP> {{tag>microcontroller "dev board"}} arduino_leonardo.txt Last modified: 2023-02-25 19:14by asdf
