Discussion
ARUni, AR Universal board
29 April
ARUni and accessory set are available at http://ar9x.net -- update --- name of board has changed from "AR9x Universal" to "AR Uni". -------------- Hi All AR9x came out about a month ago and it's doing great for Turnigy 9x, FS-TH9x. Currently it's out of stock and next production is scheduled before Feb. During this production, I started the project that can convert old TXs into latest open source featured TX. It has all the features from AR9x; - Latest Ersky9x, OpenTx firmware operated - ARM 32bit mcu - USB, SDcard, Audio - more detail, please refer AR9x thread. One difference from AR9x is the size of board. It is very small and expected to be fit into most TX's body. I'm trying to make it as small as it can be, however right size should be discussed. Also, it has all the connectors in 2.54mm(100Mil) standard header pins will allow easy modification for most TXs. USB, SDcard interface board connects to main board with FFC, so it can be placed on the side or front of TX. PCB board design is just started and before finish it, really like to hear some ideas and thoughts about this to make it better for all interested in. As it's only board, LCD must be required and it can be offered together with board. (http://ar9x.net/index.php?route=prod...tegory&path=26) my personal goal is to release this board before mid Feb. Price, of course it should be less than AR9x. Any progress should be posted. Thanks. JK

my first TX to be converted is MC3030 from multiplex.
It is still one good TX but analog trim really bothers me. ---- update --- here are few conversions and related tips |

This is great!
Couple of suggestions:

I have couple of suggestions;
1. Please separate the ground between TRIM keys and MENU keys. I use two 5-Way navigation switches for digital trims, as well as menu setting, by selecting the appropriate ground by "PRGM-OPER" SPDT switch. By doing this, I can save a lot of knobs and switches on the front panel. Actually I reduce switches from 10 to 3. I am sure that you can reduce I/O count by multiplexing them. 2. As for the board size, please keep it AS IS. The 4-corner mounting holes are the "exactly" the same size of these in old MP8000 radios ![]() 3. I wish I had trims for AUX analog outputs. I plan to use analog sliders (PAN and Tilt) with center detent, but I want to change the center setting during the flight. I can use them in leveling the flight stabilizer on the fly. 4. This is nothing to do with the board itself, but just is my f/w wish list. Flight Modes should include the curve and various switch setting beyond trims on the control surfaces. I enjoy the "Full" FM (each mode has a complete aircraft setting) with 9Z , but the programming is a nightmare ![]() |

Oh, you have an extinct 9XR board
![]() 1. In AR9X, MENU ground is not tied to GND and it is controlled by software to scan the nav switch states. 3. If you add trim pots in serial like old analog trims, you can adjust center of the sliders without changing any hardware/software. 4. Are you talking about Futaba 9Z? If you add enough 3 pos switches, you can program the radio similar to the flight conditions in Futaba 9Z WC2 radio. I programmed the complex flight conditions in my days of pattern flying but as far as programming is concerned, IMHO, 9x software is far more logical than 9Z. |

how about this, board only provide 3.3V level of UART(serial) signals pins and use seperate very tiny TTL-to-RS232 convertors? |

All pads are 2.54mm standard pin holes. SDcard daughter board size, it has be together with USB connector and two mount holes on both side. |

LCD extension pin holes are located right from FFC LCD ribbon connector.
No header pins will be mounted as it's getting way of FFC LCD ribbon cable. It's standard 2.54mm(100mil) holes so should be fairly easy to solder. |
