Arduino Kits that have a small LCD 2 line 20ish chars with uSD Card

I'm looking to make an equipment emulator for equipment I use at work, the equipment using USB as the interface. Ideally I'd place two text files on the SD card one tx.txt and one rx.txt. When the Arduino receives a command via USB it would it would look the received command up in the rx.txt file and respond over USB with the response for that command. The LCD on the first line would display the command received and the second line would display the command sent back in response.

Seems pretty easy, and I'd think someone over time has done something similar maybe.

We have highly specialized equipment used for EMC work like Amps, Signal Generators and Analyzers, I've written some Python code that controls all the equipment together. When I work from home I'd write my code but have to wait to test it till next day.

Does anyone know of an Arduino kits similar to that description or of a similar type of project?

Programming would be a whole lot simpler to use a separate file name for each message you want to display.

Ah, yes good idea, "RX Cmd, TX Response CMD" Yes that would be easier, less file handling and look up / reading, so basically .csv format

Yes. This by @trek2120

I guess I could use this device and forgo the SD Card Option and hard code the RX/TX commands in an array, what do you guys think?

It appears to need IDE 1.x.

The TOSduino Uno R3 requires the 1.0 drivers folder in order to install properly on some computers. We have tested and confirmed that the R3 can be programmed in older versions of the IDE. However, the first time using the R3 on a new computer, you will need to have 1.0 installed on that machin

It seems to me 1602+button shields exist without the requirement for IDE 1.x.
