+# Errata
 
+## v1.0 -> v1.0.1
+
+In v1.0 the incorrect LCSC part number for DB9 male connector was recorded. If you've ordered the PCBA from JLCPCB by building the v1.0 release, the DB9 connector is likely incorrect. 
+
+**How to tell?**
+
+If you have DB9 female connector assembled, you will have the incorrect part. 
+
+**How to fix?**
+
+You can de-solder the DB9 female connector and replace with the DB9 male connector. If you would like to order from LCSC, the part number is [C426221](https://www.lcsc.com/product-detail/_FOXCONN-_C426221.html).
+
+The v1.0.1 already includes the fix.
