About the only place to sell 6 digit displays complete is robotdyn - -https://robotdyn.com/6-digit-led-display-tube-7-segments-76x19mm-tm1637-red.html.. they sell the 0.56" and the 0.36" sized displays in a variety of colours however... I am having a problem with multiple TM1637 powered displays that is, as yet, un-resolved...but it may be just me that has this problem..no one else seems to be complaining...
Another option might be to use a pcb that houses the 3 digit display modules and a max7219.. I have just designed and had a batch made from JLCPCB...awaiting delivery
I could post the gerber files if they were wanted
Hi guys. Same problem. Trying to build my own. Is a serious nightmare, all those wires. Has anyone tried one of those max 7219 modules where the digits are detachable? Green ones on Ebay. Could you substitute in a 3 digit?
I've made several 3 and 4 digit displays myself with max 7219. Only difference is the 3 Digit has one less pin which is D4 on 4 Digit one. Rest of pinout is the same. Interesting to try. Have some on order so will try when they arrive.
You can make any digit size display with Max7219 chip, how to connect - below on this page - http://simvim.com/tech_num.htmlBut, you can make it using the convenient LED Matrix MAx7219 module - just connect the 7-segment indicators instead of led matrix: http://simvim.com/svc_digout.html (see the "Matrix LED Output" chapter in the middle of the page)Vlad
