+- **Lots of Flash and RAM** - A larger planner buffer could be used and more features could be added.
 - **I/O** - It has just about the same number of pins as an Arduino UNO, the original target for Grbl
 - **Peripherals** - It has more timers and advanced features than an UNO.  These can also be mapped to pins more flexibly.
 - **Connectivity** - Bluetooth and WiFi built in.

 ### Issues / Changes
 
 1. **Direction pin delay** - Not implemented yet. Some drivers require a couple of microseconds after the direction pin is set before you start the step pulse. The original plan was to [use the RMT feature](http://www.buildlog.net/blog/?s=rmt), but that has issues when trying to use it in an Interrupt.  **This is typically a option in Grbl that is not used.**
-2. **Limit Switch debouncing** is not supported yet. It does not seem to be a problem on my test rigs. It might be better to us an R/C filter for now.
+2. **Limit Switch debouncing** is not supported yet. It might be better to us an R/C filter for now. The controller shown above uses R/C filters, which seems to solve the problem.
 3. **Step Pulse Invert:** This has not been fully tested. I suggest...leaving $2=0

 Be sure you have external pullup resistors on any GPIO34-39 that you use. These default to door, start, hold and reset functions.

 ### TODO List
 
 - RMT. The RMT feature is a ideal for direction and step features, but apparently has issues working in interrupts. See [this forum post](https://www.esp32.com/viewtopic.php?f=19&t=6397&hilit=grbl) and [this blog post](http://www.buildlog.net/blog/?s=rmt). It would be great to get it working.
-- Add spindle enable and direction. 
-- Add SD card. Initially only these features will be supported.
-  - Mount Card
-  - List Files
-  - Run File
-  - Get job status (bytes send / file size)
-  - (Optional) Update firmware from SD card
+- Add spindle enable and direction 
+- Wifi
+- Web Server with browser based control and setup.
