Driver board for Teensy3 with 6 high current and 7 low current FETs. On-board regulator powers Teensy from 12V.

(Error: JP2 was connected to ground instead of +12V… positive side of load needs to be connected elsewhere…)

• Assembled, TESTED, and works awesome.
• nRF905 at 915 MHz.
• Uses Johanson 915 MHz chip antenna P/N 0915AT43A0026.
• LEDs on all three interrupt pins for visual feedback.
• Do not exceed 3.3V for IOin and Vin. There is no regulator or level shifting. Shouldn’t need to level shift IOout. There are six (6) inputs and four (4) output IO pins.
• All values indicated on board are good. Three (3) LEDs and three (3) resistors are not marked, because color and brightness are by preference.

Gandalf ist eine Stand-Alone Lösung für portable Bestimmung von Laserleistung auf Basis von MyPhotometrics - Sauron. Sauron ist ein hochauflösender 4-Kanal Photodiodenverstärker, der mithilfe von geeigneten Photodioden die Strahlungsintensität einer Lichtquelle erfassen kann. Mit der Erweiterung Gandalf ist es möglich Messungen ohne eine Verbindung zum Computer durchzuführen und die kalibriert gemessene Laserleistung anzuzeigen. Bestehend aus Anschlusskontakten für Sauron, einem LCD Display, einem Playstation Joystick, sowie einer Trägerplatine zur Aufnahme eines Arduino Nano, liefert Gandalf ein praktisches Userinterface. Die Spannungsversorgung erfolgt mithilfe von Batterien in einem Spannungsbereich von 6-12V. Desweiteren ist das Messgerät auf einen EB3-Anschluss erweiterbar. (Aufgrund von geringer Verfügbarkeit der passenden Buchsen, wird dieses Feature allerdings erst in Zukunft erweitert.)

This is a V-USB development board meant to fit inside a metal (possibly scavenged) USB type-A shroud.

The board will probably need to be sanded down on the long sides to fit well. The thickness of the board and the shroud should be just about perfect to provide a nice, solid USB connection. The bottom layer also exposes a VBUS trace that should be insulated from the shroud with kapton tape, solder-mask pen, etc. After all that, carefully superglue that lil' sucker inside the shroud. If you don’t want the ISP header, feel free to cut along the advertised line. The board /should/ be near flush with the edge of many shrouds.

Ideally, this design would be software compatible with the adafruit trinket 5v. D+ and D- are swapped from the adafruit schematic, so you’ll have to alter the code. It doesn’t support a regulator, have a reset button, or any other schnazzy bells and whistles, so YMMV.
