David Pitts is starting to roll out the pixel products for the Falcon pi player. These have mind blowing capacity (per dollar) compared with the controllers we've all been using here. Here are the details from David's Facebook post:

F16v2 presale is open.

The F16v2 beta has been going good. We have successfully driven 680 pixels per string in 16 string mode and 340 pixels in 32 string mode. The controller receives 64 universes of E131 data no problem. The DMX outputs all are working. This pre-sale will be for completely assembled boards and boards will be delivered in July.

We are not sure how long the presale will be open due to the short time frame to delivery. I would expect it will not go longer then two weeks or 50+ boards of each. To be determined.

Board current specs

Board can be powered from pixel power or external power. Both inputs can be 5-24VDC.
Power output port to power switches.
An additional optional 5-24V switched regulator can be added to give an additional 1.5A of power if needed on a 2-pin connector.
Two independent sides of power. Each one can be a different voltage.
(Expansion board also has two independent pixel power inputs giving 4 independent ports of input power when using 32 string mode and expansion board)
16 - Fused outputs for main board and expansion board.

Number of strings
16 strings or 32 with expansion board.
All strings can use any of the 32768 channels this controller can receive as a start address.
Each string can be independently configured for null nodes, zigzag, forward/reverse, node type, pixel count , grouping etc...

Pixel per string
680 pixels per string in 16 string mode or 340 pixels per string with additional expansion board ($50US) using 32 string mode.

String Types
All string ports can be any of the following string types. They all can be independently set.
WS2801 / WS2803
WS2811 / WS2812 / TM1804 / TM1803 / TM1809 / TM1812 / SM16715 / INK1003
TLS3001 / TLS3002 / CY3005
LPD6803 / D705 / LPD1101 / USC6909 / UCS6912

String Types to be added in near future
1903,SM16716,MBI6020,GE Color Effects, P981x, APA102
(We can fit two more in current image. Additional formats will be added to an additional image which will be held in flash making switching images as easy as selecting image in user webpage interface.)

DMX/Renard/Pixelnet Outputs
4 - Dedicated RS-485 outputs

LCD Display,Push Buttons and Indicators
.96" OLED 128x64 matrix display for setup and status.
5 - Push buttons to control display. Up, Down, Right, Left and Select
Power LED for main fuse/pixel board
Power LED for FPGA/Controller Board
Two multi purpose LEDS for status.
16 - Optional Blown Fuse LED Indicators (User must source LEDS)

Temperature Sensors
1 - Processor temperature sensor.
2 - Additional Sensors
(The sensors are like a little 2" two core wire. Additional wire can be added to move sensor out of enclosure to give ambient temperature outside.
One sensor will be mounted on the board and the other will be provided with unit.)

Voltage sensors
The incoming pixel voltages of main board are detected and displayed in user interface. (Display of voltages and temperatures of OLED is coming)

Raspberry PI Interface for running Falcon Player (FPP)
The controller in near future will have ability to connect directly to a RPi running FPP. In this configuration the controller can operate as a standalone controller with audio and video making it one of the most powerful platforms for driving RGB lights, music and video. All configuration of controller will be embedded into the standard FPP user interface.

Open Source
All files to produce software/firmware will be released at a near future date.
1) Expansion board must be within 1.5 feet of main board. Maybe further but no guarantee.
2) Pictures below do not show the newly added OLED display and push buttons.
3) Pictures below do not show that the Pixelnet input section has been removed.
4) Also two holes have been added to FPGA board to hold Phy connector secure with a zip tie.
5) If you live in Australia or New Zealand, DarylC will be offering the boards over there. Pricing will differ.
