This is product is just the ESP8266 Led Matrix Driver Board. You must supply the Led display yourself along with a 2mm center positive 5V, 2A power supply. Soldering, cables or wires are not necessary with this board. You can simply plug in onto the back of the display. My first version used a NodeMCU along with way too many jumper wires. This version is just one board not using using any wires or cables at all. It comes already plugged into the back of the display with a US wall plug and a microUSB cable already to be programmed with the Arduino IDE.
64x32 displays can be purchased on the cheap from a few sites like Aliexpress.
If you have a display already that you think may work then check out my attached picture with measurements in red.
I've tested and verified that this board works before testing. You must be certain that the wall wart that you use to power the project has a 2mm positive center type at 5 volts and at least 2 Amps. Plugging in a center negative barrel supply or one over 5 volts will destroy the board.
