 ## Description
 
-IO433 is an open-source ESP32 (TTGO T-Display) & CC1101 based 433Mhz sniffer.
+IO433 is an open-source ESP32 (TTGO T-Display) & CC1101 based 433Mhz sniffer. It is currently work in progress.
 It can sniff, store, replay, dump and monitor most 433Mhz (currently ASK-OOK only) signals.
 These include garage door openers, remote doorbells, sensors and similar devices.
 
 The core of this project aims to be its simplicity, reliability and versatility.
-With a couple of ICs and a by 'connecting some wires', one can start messing around with 433Mhz devices and decode their communications protocols.
+With a couple of ICs and a by 'connecting some wires', or soldering a breakout board, one can start messing around with 433Mhz devices and decode their communications protocols.
 It's mainly a proof-of-concept but already encompasses several very useful features.

-Details of the wiring between the ESP32 and CC1101. The pinout choosing is important. If changed, not only the code should change to reflect the new pinout, as one must make sure the corresponding ports on the ESP32 support the I/O operation mode that the code needs.

+**Important note**: the green wire connects to IO2 on the ESP32, regardless of what you see in some pictures.

+
+### Assembly with PCB
+
+Solder the CC1101 based module in the lower leftmost side of the pcb. The E07-M1101D will have 2x4 pins and the TI-CC1101 will have 2x5 pins. If you are using the E07-M1101D, connect the solderable jumper in the lower middle.  
 
-### Assembly with battery and 3D printed case

-If you want, you can use the 3D printed case that supports a 902540 720mAh or even a 903048 1800mAh, 3.7V battery (should last for a day or two)
+Then just solder the ESP32 TTGO module on the PCB. Add a battery or just use the USB cable to power the module. Optionally print the 3D case for your CC1101 module.
