Review on 🔧 Songhe MEGA 2560 PRO Embed CH340G Fully Compatible for Arduino Mega2560 Module – Male Pinheaders, ATMEGA2560-16AU Chip Included by James Cabot

I used this to fit into a 32 x 64 pixel LED panel purchased from Adafruit. For this use, making the display only 3/4" thick worked great. I wouldn't recommend that for beginners. This requires add-ons to the Arduino IDE programming software. Pin headers require special connectors and cables. (by Pololu) or custom ribbon cables or wire connections.Often additional power controls are needed.Nonetheless, this little unit is a reasonable replacement for the much larger Mega if you're short on space to work.
