+title: Generic 2CH Wifi Curtain Module
+date-published: 2024-08-13
+type: cover
+standard: global
+board: bk72xx
+Difficulty: Soldering required
+---
+
+## General Notes
+
+This is a generic dual channel curtain module using a BK7231N chip. To flash it you need to solder 3.3V, GND these are easily accessible at the front of the module.
+Also RX, TX which are at the inner side of the module next to one of the relays.
+The whole wifi module is suspended on pins because there is a relay under it. So I just bent the wifi bord a bit just to make enough space for soldering the two wires.
+It uses a wifi board called CBU.
