Piccolo3 System User Guide. Section 07. Power supply requirements

QEPro and NIRQuest: Ocean Optics provide a 100-240v 50-60hz 1.2A input/5v ~5.0A  output power supply. This has a barrel plug which presumably is a USA specification. A DCPP2 – DC Power Connector, Plug, 5 A, 9.5 mm, Cable Mount, 2.5 mm seem to be the European equivalent (Farnell part 224935).

The Piccolo team supply a Piccolo Power Block/(inverter/distributor) to provide 5v ~5.0A  from a 9-36v input to power Ocean Optics cooled spectrometers for field or UAV use. Note minimum supply to these should be 12v as shutters require minimum 10.7v to operate. See manufacturer’s data sheet for details.

Note the cooled spectrometers (fan and cooler) draw ~1.4A on (max measure has been 3A) startup and run at approx ~ 0.6A.

USB2000+ and Flame spectrometers draw their power from the Piccolo’s USB port.

Piccolo controller/RPi power supply: The piccolo controller needs a nominal 12v ~ 3A  power supply to power shutter and Raspberry Pi (the RPi is powered from the Piccolo controller which steps the voltage down to 5v) . Th Piccolo fore optic shutters draw ~1.2A at startup at start of day and ~0.8A for each shutter switching but only draws this for ~5ms to open the same again to close. The power supply to the Piccolo controller/RPi can be taken from a dedicated terminal on the Piccolo Power Block.

The electrical connector on the Piccolo control board is RS PRO 5mm Pitch Straight PCB Terminal Block, Screw Terminal Block, PCB Mount, 2 Way or similar. TeamPiccolo use either a AMASS XT60 female to take power from a LiPo battery or a P-Tap to take power from a DJI Ronin-MX gimbal.

Tracer 12V 16Ah batteries may offer a useful power source for Piccolos with cooled spectrometers for field use.

There is a wide range of LiPo batteries available and TeamPiccolo can make no recommendations. On UAVs we normally run the Piccolo and cooled spectrometers from the Ronin-MX gimbal aux. power supply.

M600 Ronin-MX:  large capacity battery 15.2v 4350mAh 66h; Std capacity 14.v v 1500mAh 22.7Wh and Ronin-MX power distribution board has 2 x P-TAP each rated at 12v.
