Diymall Atmega328 Atmega328P Arduino Esp8266 Computer Components Review

Excellent processor ardiuno! Works exactly as described. Good price . Good quality. Make sure you have a programming method as these tiny bare bones don't have a micro USB. You can buy a separate module that will do the programming if you solder the right pins.

When connected to a USB output of a PC (5V) the pinout gave me 5V. When I actually connected it to a 3.3V V power supply connected, I got 3.3V on the pins.

Came in when he said he would and works great. Now I can connect my 3.3V sensors to this microprocessor without having to come up with any kind of level switch.

The first target of my burgeoning soldering skills, this board has withstood all manner of abuse in cold blood, including re-soldering, re-soldering and numerous unintentional shorts between multiple different components. . If the board had failed, I would have put aside my attempts to continue my studies in elementary electronics. Instead, I'm happily contemplating my next little project and will definitely be buying the Pro Mini version from Diymall again.

I bought several of these and they work very well. I am using this board in a solar powered remote sensing project connected to an Xbee Pro radio. The built-in voltage regulator (KB33) can handle the maximum output voltage of the solar controller (18V) and provide enough current to transmit sensor data over the Xbee radio (250mA).
