Mega 2560 Promini ATmega2560 16AU Compatible for Arduino Mega 2560 Mega 2560 Promini Compatible for Arduino Pro Mini and Atmega2560 3 3V no pinheaders

RobotDyn — Mega 2560 PRO MINI it is version PRO of Arduino Mega 2560 R3. Built on the Atmel ATmega2560 microcontroller. The board has compact size 38×52mm. It is a good solution, to make your final project on solder prototyping board. You can find all pinouts on board: digital's I/O - 70 and analog's input - 16. Mega 2560 PRO MINI as functionality similar to the Arduino Mega 2560. It is built on MINI board, but the same stable, and uses the original chips ATmega2560 (16MHz). The board doesn't have USB interface. For connecting to PC, pls use the USB-TTL converter to serial RX/TX bus. You can supply power to board through the power pin-headers. Output current for 5V version - about 800mA, for 3.3V version - about 800mA (Please note that the higher the input voltage the lower the outgoing current). That will provide a reliable power most of your initial projects. On the picture, you can see the real size of this board, compare with the size of Mega Rev3. Feature: Form-factor — PRO MINI; Microcontroller — ATmega 2560 (16Mhz); Input voltage — 6-9V (peack 18V); I/O — 70 digital, 16 analog; UART — 4 bus; PCB size — 38mm×52mm Documents (Instruction manuals, schematics, etc): https://robotdyn.com/mega-2560-pro-mini-atmega2560-16au.html RobotDyn(R) — registered trademark in USA.
