Renard PX1 Pixel Controller

Renard PX1 Pixel String Controller

---

General

The Renard PX1 is an inexpensive Pixel controller designed to be a pixel controller that utilizes the stand Renard format and controls. It can be daisy chained with other Renard controllers. The design consists of a controller board with a PIC16F1825

Features

Standard Renard connections 5VDC and 12VDC operation WS2801 and WS2811 pixels Some Design Details:

1) One output (same 3.5mm connector and pinout as jstjohnz's controller), handling up to 200 pixels 2) RS485 input, same RJ45 pinout and protocol as Renard controllers 3) 115200 input baudrate (lower rates provided, but not recommended) 4) Uses PIC16 parts, so existing programmers should work. 5) Supports WS2811 strings at with either 400KHz or 800 KHz data rate, 5V power input 6) Uses external 5V supply (readily available from Ebay, China, etc). 7) Power, RxD and FE (framing error) indicators 8) Jumper to select pixel speed (400 KHz vs 800 KHz)

The PCB has been designed, with just a few details to be worked out after I receive some connectors to make sure that they fit. I haven't sent the board out for fab yet. The firmware is a work in progress, although I have verified that the microcontroller that I've selected can control the faster WS2811 pixels. First jumper is used to select between a chase and a solid static pattern. Other three jumpers select one of 12 possible themes:

1) Orange theme (Halloween/Thanksgiving) 2) Purple theme (Advent/Lent) 3) Red & Green (Christmas) 4) Red (or pink) Valentines Day 5) Green (St. Patrick's Day) 6) White (Easter) 7) Red/White/Blue (4th of July)

With five possible other themes (national day colors for other selected countries???)

Assembly Instructions

Assembly of the Renard PX1 is done in two steps:

1. Assemble PCB and Solder parts
2. Configure Jumpers

Renard PX1 Pixel Controller Assembly

1. Begin by inspecting the PCBs to look for any defects such as cracks or breaks. The holes on the board should be open on both sides. Then inspect and sort out the various parts for the boards.
   

1. Install resistors
2. Install capacitors
3. Instal IC sockets
4. Install LEDs
5. Install the headers. The short end of the header is soldered into the PCB.
6. Install the voltage regulator
7. Install ICs
   1. Install the 14 pin PIC in
   2. Install the 8 pin RS485 chip in

J12 and J2-Renard Input and Output

NEEDS WORK
The two 3 pin jumpers J2&J3 near the bottom left side of the board are used to bring DMX signals to and from the board. The 3 pin connectors are polarized and should be connected as follows:
Pin 1 is the Square hole of the three holes on the side towards the center of the board: Connect to DMX Ground
Pin 2 is the center hole of the three holes: Connect it to DMX Data -
Pin 3 is the left most hole of the three holes: Connect it to DMX Data +
Note that the two 3pin DMX connections are setup as a thru connection and can be used as either the input or output of the board. If the LEDancer is the last connection on a DMX data line, it may be necessary to add a 120 ohm terminating resistor to the unused DMX terminals between PIN 2 and Pin 3.

J6-ICSP Programming Header

NEEDS WORK
J4 is the 6 pin header located in the bottom center of the board. J4 allows the PIC microprocessor to be programmed in place on the board by directly connecting a PICKIT2 or PICKIT3 programer.
Pin 1 is the square hole towards the right side of the board closest to D1.

J9-Power

NEEDS WORK
J1 is the 2 pin header located at the top left side of the PCB. The LEDancer can be powered by 5-24VDC. If you are using 5VDC, omit the voltage regulator and jumper the voltage regulator position by soldering a wire jumper to where the two outer pins of the regular would have gone in position U1 near the top left side of the PCB. If you are feeding greater than 5VDC, then you must use the on board voltage regulator.
Round Hole closest to the top of the board: Positive Power feed
Square Hole: Negative Power feed

J1 and J2-Renard Input and Output

NEEDS WORK
The two 3 pin jumpers J2&J3 near the bottom left side of the board are used to bring DMX signals to and from the board. The 3 pin connectors are polarized and should be connected as follows:
Pin 1 is the Square hole of the three holes on the side towards the center of the board: Connect to DMX Ground
Pin 2 is the center hole of the three holes: Connect it to DMX Data -
Pin 3 is the left most hole of the three holes: Connect it to DMX Data +

If the LEDancer is the last connection on a DMX data line, it may be necessary to add a 120 ohm terminating resistor to the unused DMX terminals between PIN 2 and Pin 3.

J10(4 pin)- Output to Pixels

NEEDS WORK
J5 is located along the right edge of the board and is a 8 pin connector used to connect to the LED Segment PCB. Pin1 of the connector is marked by the arrow next to it on the silkscreen.
