Arduino Mega 2560 (clone) Review and Test (#128)

This re-imagining of the Arduino Mega has all the features, but in a board smaller than the Uno. I test it by adding a temperature sensor (DS18B20) and a 0.96" OLED display to make a digital thermometer.

As a big fan of the powers of 2, I'm also thrilled to reach this landmark video of 128 (2^7).

Errata: my OLED is 128 x 64 pixels, not 128 x 32

Lol so many pins would be shorted if you put this into a breadboard. Luckily, power won't be shorted to GND, but TX shorted to RX will give you a hell of a time haha ... AREF to RESET might drive you nuts too hahaha

It's a great board if you need lots of 5V compatible pins (as I did!).

A very interesting board and look forward to see what else you do with it Martyn. Great video as usual!

Ps. Cold hands, warm heart... so my Nan use to tell me ;-)

great for people that like vintage computers operating at 5v and need to interface with Address, data, control buses

Hello Mr. Davies, Could you please tell me what kind of camera being used to display board on this video? Thanks

[Jason-Vash]

hey you know if i can run this board as a joystick pedals controller?

Hi! I have two of theses boards but I can't get a connection to PC. There is no COM port in the device manager. Hope you can help.Thank you

This is a more manageable size of board for practical use if you want to fit it into projects where space is at a premium!

Sir, can you share where to buy this small Arduino Board?

I need to use an accelerometer sensor and microphone at the same time. Are there sufficient analog and digital pins?

[MrAmity]

you can't use a breadboard here
because the pins are dual row, so one pin would interfere with the previous one
