This is a new variant of the popular phi-2 shield with 20X4 displays yellow back light. I made a small PCB batch of 12 and they sold out in a month or so. Now the second small batch is in so they're back in stock. Thanks to my supporters that and helped me press the order button for this second PCB batch 
This display size will take full advantage of the latest update on phi_prompt library.
I have set up the sales page on www.inmojo.com

List of features:
- Compatible with UNO, Duemilanove, official Ethernet shield, MEGA and clones
- Best interactive user interface software to make menus and ask user inputs: phi_prompt, only for phi shields.
- 20*4 character LCD (yellow back light) to display information and interact with users
- Six buttons for input and interaction
- 2 RJ45 ports providing up to 16 robust connections to sensors or control devices.
- A buzzer for alarm or simple tones.
- A sensor block to test most common sensors, such as thermistors for temperature, resistive pressure sensors, light-dependent resistor for light, Hall Effect magnetic sensors etc.
- Two LEDs indicators. You are free to choose which arduino pin to drive the LEDs.
- Real time clock with battery backup keeps the time when Arduino is turned off
- EEPROM to log data and keep data when Arduino is turned off (24LC256 or 24LC512)
- Reset button for Arduino
- All Arduino pins are brought out for maximal flexibility.
- The I2C bus is brought next to analog pins 4 and 5. UNO uses these pins for I2C while MEGA uses 20 and 21.
