FRED

Developers Martin Pischky, Stefan Bormann Project informationen http://fremodcc.sourceforge.net/diy/fred/fred_e.html Description First do-it-youself throttle of FREMO Notable Legendary look-and-feel, because it is derived from the old analog throttle Thousends are build Commissioning is not as simple as it could be

FREDI

Developer Olaf Funke Project informationen http://fremodcc.sourceforge.net/diy/fred2/index.de.html Description Second generation FRED. There are two variants: with potentiometer and toggle switch for direction, as we are used from the original with rotary encoder as known from the intellibox Notable simpler to build, less components more function keys (F0..F8) simpler commisioning (no adjustment of ADC) Further development exists, e.g. SWD-FREDI with more functions. But I don't know any public site I could link to.

wiFRED

Developer Heiko Rosemann Projekt documentation https://newheiko.github.io/wiFred/documentation/docu_en.html Files at GitHub https://github.com/newHeiko/wiFred Description Cordless handheld throttle with WiFi. Connection to the layout is established via the wiThrottle protocol. Project status First devices were used successfully on FREMO meetings. A bulk order for about 100 devices was started end of 2021.

Uhlenbrock-FRED

Manufacturer Uhlenbrock Elektronik Product information Produkt archive Description Commercial version of FRED. The following features are added: More function keys (F0..F8) An additional mode for loco assignment for easy switching between four locos - works only together with Intellibox FREMO operation Unfortunately quite big, therefore it does not fit in the normal FRED tray In order to reduce the power consumption, the LEDs should be dimmed For walk around operation important: one of the option switches [F1] controls wether an emergency stop is issued when the loco is assigned. Unfortunately this also works on every plug in → disable it. There are two versions of the FRED software. The very first one contains a bug that leads to a flashing direction LED on every plug in which stops the train; send to Uhlenbrock & ask for an update. - this bug is only relevant for walk around operations. Apparently this device is no longer available from Uhlenbrock

Digitrax UT4

Manufacturer: Digitrax Product information: http://www.digitrax.com/products/throttles/ut4/ Description: The only throttle with potentiometer and toggle switch for direction by Digitrax. FREMO operation: Attention with the tiny rotary address selectors Many functions: F0..F12
