All components used for building ARC1 will be introduced in the following. To make shopping easier, I collected some distributor links with prices. I will try to keep the component lists, links and prices as up-to-date as possible, but due to the \u201cprototyping\u201d nature of some of the parts, availability won\u2019t be assured forever. Luckily, in most of the cases replacement parts can be found easily. With small changes to the firmware, they can be supported in future releases.<\/p>\n

Not all of the components listed here are necessarily required to run ARC1. If you don\u2019t plan to use Bluetooth \u2013 just ignore it. The same applies for the LED ring around the speed control dial. No changes in soft- and hardware are required if you just don\u2019t connect those components.<\/p>\n

The Controller\u2019s Base Board<\/h4>\n

The centerpiece of ARC1 is a development board of ST Microelectronics. It\u2019s based on an ARM Cortex-M4 microcontroller (STM32F429ZIT) and is shipped with a 2.4\u201d Color TFT-Display with resistive touch. Contrary to other popular development boards (such as Arduino, Olimex etc.), this ST board offers easy access to all I\/O pins, provides an onboard programmer\u00a0 \/ debugger and offers great value for money. The board can be supplied with power either via USB or via a separate 5V input pin.<\/p>\n

All technical details and comprehensive documentation (manual, schematics, Gerber files, BOMs etc.) can be found on the manufacturers website<\/a>.<\/p>\n\n\n\n\n\t\n\n\t\n\t\n\t\n\t\n\t

Speed control dial (encoder) and LED ring display<\/h4>\n

An encoder is necessarily required by ARC1 for speed control and in order to navigate through the GUI. You can use almost every available rotary encoder with A\/B signal outputs. If it also provides an integrated pushbutton, the better, as it will make menu navigation much more comfortable. Of course this pushbutton can also be external from the encoder.<\/p>\n

An optical representation of the locomotive speed can be provided by two supported LED ring displays.<\/p>\n\n\n\n\n\t\n\n\t\n\t\n\t\n\t\n\t

Bluetooth-Interface (optional)<\/h4>\n

The Bluetooth-Interface allows controlling ARC1 and thus your model railroad with an Android portable device. In general, all Bluetooth-modules providing SPP (Serial Port Profile) can be supported by ARC1. Because SPP is based on the Generic Access Profile (GAP) and is thus provided on almost all Bluetooth modules, this should be no issue. However, there are only a few Bluetooth breakout boards that work in SPP mode by default and don\u2019t need extensive initialization effort. The presented Bluetooth-Bee module is based on HC05\/HC06 modules and is a great breakout board. The connection to the ARC1 base board can be done by jumper wires, but caused by the very short pins, soldering would be the preferred solution for once.<\/p>\n

Accessories<\/h4>\n

For interconnection of the components, using so-called jumper wires is the preferred and easiest solution. Those wires are shipped ready-for-use and can easily be plugged to pin headers without soldering. The minimum length of the jumper wires should be 150mm and both sides should be female (F\/F). Jumper Wires can be obtained from almost all electronic shops and distributors but prices can vary considerably. Best value for money is given by jumper wires that come as a ribbon cable \u2013 and you also have the choice of keeping a part of the ribbon when having multiple data lines per module. Some alternatives are presented in the following:<\/p>\n\n\n\n\n\t\n\n\t\n\t\n\t\n\n\t\n\t\n\t\n\t\n\t

Fahrtregler-Drehknopf (Encoder) und LED-Ring-Anzeige<\/h4>\n

In jedem Falle ben\u00f6tigt die ARC1-Zentrale einen Eingabe-Drehknopf als Fahrtregler und zur Men\u00fc-Navigation. Es kann daf\u00fcr jeder beliebige Inkremental-Geber (Dreh-Encoder) mit A\/B-Ausgang an die Zentrale angeschlossen werden. Vorzugsweise ist in den Encoder gleich ein Taster integriert, der beim Dr\u00fccken des Encoders ausl\u00f6st. Das macht die Men\u00fcf\u00fchrung deutlich intuitiver. Nat\u00fcrlich kann dieser Taster auch extern angeschlossen werden und muss nicht zwingend in den Encoder integriert sein.<\/p>\n

Zur optischen Darstellung der Geschwindigkeit werden zwei alternative LED-Anzeigen unterst\u00fctzt.<\/p>\n\n\n\n\n\t\n\n\t\n\t\n\t\n\t\n\t

Bluetooth-Schnittstelle (optional)<\/h4>\n

Die Bluetooth-Schnittstelle erm\u00f6glicht das Verbinden der ARC1-Zentrale mit einem Android-Mobilger\u00e4t, um dieses als Handregler und zur Anlagensteuerung einzusetzen. Prinzipiell werden alle Bluetooth-Module unterst\u00fctzt, die im SPP (Serial Port Profile) arbeiten k\u00f6nnen. Da SPP auf dem Generic Access Profile (GAP) aufbaut und somit von (fast) allen Bluetooth-Modulen bereitgestellt wird ist dies vorerst kein Problem, jedoch gibt es nur wenige “Fertigmodule”, die von Haus aus im SPP Modus arbeiten und ohne aufw\u00e4ndige Initialisierung auskommen. Das hier vorgestellte Bluetooth-Bee Modul basiert auf HC05\/HC06 Modulen und stellt bereits ein bequemes Breakout-Board dar. Prinzipiell kann auch hier mit Jumper Wires gearbeitet werden, um das Modul mit der ARC1-Zentrale zu verbinden, jedoch ist aufgrund der kurzen Pins und des kleinen Abstandes L\u00f6ten empfohlen.<\/p>\n

Zubeh\u00f6r<\/h4>\n

Zum Verdrahten der einzelnen Komponenten empfehlen sich sogenannte “Jumper Wires”, also vorkonfektionierte Kabel-Steckbr\u00fccken, die auf die Stiftleisten der Boards passen und eine bequeme, l\u00f6tfreie Verkabelung erm\u00f6glichen. Die Mindestl\u00e4nge der Jumper Wires sollte 150mm betragen und die Kontakte sollten auf beiden Seiten als Female, also als Buchse, ausgef\u00fchrt sein (F\/F). Jumper Wires gibt es bei nahezu allen Elektronik-Gesch\u00e4ften und Versandh\u00e4usern, die Preise fallen jedoch sehr unterschiedlich aus. Vom Preis-Leistungsverh\u00e4ltnis am besten sind die Jumper Wires, die als Flachbandkabel ausgeliefert werden. Man kann sich also entweder st\u00fcckweise Kabel abtrennen oder hat gleich sauber verlegte “Datenautobahnen”, wenn zwei Module miteinander verkabelt werden m\u00fcssen.
