I had intended the solder the modified TM1637 to the microcontroller's strip board however I later discovered that the USBTinyISP failed to work. The ICSP shared pins that were also used by the TM1637.  I did manage to get the USBAsp ISP to work however I thought it would be better to allow the 4-digit module to be plugged in or removed as needed. I could then use this module in other projects.
Luckily I had bought an assortment of female header pins from Ebay that also included a 4x1 size which saved me from cutting a longer one.
