The TIL311 had a alphanumerical brother the TIL305. This was a 5x7 LED matrix in the same form factor. Similar to #PICTIL, which is replacement for TIL311 this can replace TIL305.
This is more a fun project, or side project of #PICTIL. There are still original TIL305 available. And also other pin compatible parts (like LTP-305). But only with red or green LEDs. Also the character size will be bigger with reDOT.
If you want to try building it and soldering some 0402 LEDs, you can get your own boards from OSH-Park: But order them on your own risk. The boards do not full fill OSH-Parks design rules. With 5mil traces and spaces they are a little bit smaller. But for me that is more a prove that they can handle also 5 mil, which fits much better in my normal grids.
