+### Marked v3
+
+There seem to be many versions of this board. I have confirmed the one labeled as v3 (marking on back) works
 out of the box with no module modification (outside custom ESP code). 
 
+- Also identifed by dual row of pins on side

+### HW-655
+
 - There may be one version labeled [HW-655](https://www.youtube.com/watch?v=D470BrL15wA), that looks to work out 
 of the box as well. 
     - *UPDATE* 2020-07 just recieved one, and it did not work out of the box in either digital or serial modes.  
-May try the controller flash (below) to OCD all the things.
+May try the controller flash (below) to OCD all the things. 
+    - Does appear that the Flashing is needed for this version to work as well
+
+### General
 
 - Finally, many knock-offs of this board exist. One idenitifcation of a knock-off is a continual LED flashing on the module
 but the relay code does not work. There is a very [in-depth conversation](https://www.esp8266.com/viewtopic.php?f=160&t=13164) about this, as well as all over the rest of the internet. There is a fix to [flash the onboard-mcu (STC15F104W)](https://www.esp8266.com/viewtopic.php?f=160&t=13164&start=68#p74262). The referenced HEX code there does not appear to work, but another user posted an [updated version](https://www.esp8266.com/viewtopic.php?f=160&t=13164&start=96#p81907) that does work. Additionally, you can follow that thread on how to modify the board (remove the micrcontroler, solder some jumpers) and control it with one of the GPIO - this process is hard for the novice solderer.
 
-    - To flash using [STCGAL](https://github.com/grigorig/stcgal) 
-     ```
-     stcgal -D -p /dev/tty.usbserial-1410 -P stc15 -t 11057 -b 1200 /path/to/file.hex
-     ```
+#### Flashing MicroController
+
+- [STCGAL](https://github.com/grigorig/stcgal) 
+
+- Install
+
+    - python3 -m pip install stcgal
+    - ls /dev/tty.*
+
+- Flash 
+
+    - stcgal -D -p /dev/tty.DEVICE -P stc15 -t 11057 -b 1200 /path/to/file.hex
+    - trimming (-t) may not be needed
+    - baud (-b) seeems to be required at 1200

 # ESP 8266 Alexa Enabled Relay
 
-## Prerequisites
+## Board Versions
+
+### Marked v1
 
 - [ESP8266 WiFi 5V 1 Channel Relay Delay](https://amzn.to/2BLYMoP)
 - You need to modify the board (YMMV). [A](https://www.esp8266.com/viewtopic.php?f=12&t=16732), [B](https://www.youtube.com/watch?v=Uq7ZfutOSSg)
+- After modification, works in digitalMode
+
+### Marked v4
+
+- Also identified with mounting hole on board
+- Works in digitalMode out of box.
+- By far the easiest/ideentifiable of boards
+
