Works like a charm with my Raspberry Pi Zero V1.3 and Pi Zero W 2 boards. All I needed to do was download tm1637.py from Github (I'm using the depklyon version of tm1637, search for it), hook the power (VCC and GND) pins to 3v3 and ground pins (17 and 20 in my case) and the CLK and DIO pins to GPIO pins (GPIO23 (pin 16) and GPIO24 (pin 18)).For the python code add these lines in the appropriate places:import tm1637#declare variablesCLK = 23DIO = 24tm = tm1637.TM1637(clk=CLK, dio=DIO)#adjust brightnesstm.brightness(0)#then call tm.show(x) to print a string to the 7 segment displaytm.show(str(x))Then let the learning and fun begin!

Not much to say but they are round-of-the-mill TM1637 4-digit 7-segment display. They use their own protocol so don't mistake them for I2C and there's actually you can do with them then you might realize in terms of animations thanks to the IC behind the segments.

Only comolaint is they soldered the headers on the top of board. Made it impossible to flush mount them in my project had to slightly recess.

Nice and bright, but not over-driven, good size and a fantastic price.Only minor issue is that they soldered the four-pin connectors on the wrong side, making removal required if you want to actually mount these to a panel. Be sure to bring your desoldering skills.

I was not clear on what the measurements meant in the product description. These were smaller than what I ultimately needed, but they work well and are easy to use. The 0.36" measurement is the actual height of each digit on the display.I used these with an Arduino and an open-source library with no issue.

I used them in a few projects and they worked as intended.Id definitely buy them again.

I'm really happy about the amount of modules I got for the price point. 5 for $17 is great!These modules all functioned during my testing, and they all do the job they are supposed to do! Great!

Needed something cheap to test a concept. Worked so well, I've ordered 5 more.
