Hydra: Smart DC Power Supply
DISCONTINUED. The Hydra has been discontinued and is no longer available for purchase.
The Hydra is a triple-output power converter designed to make it easy to get the power you need for your next project: simply grab the closest battery or AC/DC adapter, plug it in to the Hydra, and you’ll immediately have access to three independent, software-configurable DC output voltages to power your system.
With its palm-sized aluminum case, the Hydra provides all the flexibility of a bench-top supply without using up your desk space. And unlike a bench-top supply, you can use it anywhere: it’s small size and flexibility make it a perfect power solution, whether for a mobile robot or an industrial system.
You can control the Hydra using your computer, an Arduino or other microcontroller, or even your smart phone (using an optional Bluetooth expansion board). Using any input voltage between 5V and 14V, each of the three outputs can be set to anything between 2.5V and 14.0V via USB, Bluetooth, or serial.
The Hydra is packed with features, including reverse polarity protection, ESD and surge protection on all inputs and outputs, over-current protection, automatic thermal shutdown, and user-adjustable output current limits. When combined with the included PC software, the Hydra can function as a battery charger for lithium, NiMH, NiCD, and lead-acid batteries. And with 2.5A continuous current capability per output, the Hydra is equipped to meet virtually all project needs, including powering servos, cameras, wireless transmitters, and control electronics. This is the last power supply or battery charger you will ever need to own.
Features of the Hydra
- One input, three independent outputs
- Control via USB, serial, or Bluetooth (iPhone or Android devices with optional Bluetooth expansion board)
- Adjustable output current limit
- Current control mode allows the Hydra to act as a current source (drives high power LEDs, etc.)
- Charges batteries using the included PC software and a USB connection
- CNC-machined, anodized aluminum enclosure
- Output short circuit protection
- Thermal shutdown
- ESD and surge protection on all inputs and outputs
- Reverse polarity protection on voltage input
- Accepts input voltages from 5.0V to 14.0V
- Output voltages individually configurable from 2.5V to 14.0V
- Output voltage resolution: 0.01 volts
- Max continuous current per output: 2.5A at 5V (~12 watts available per output at any voltage level)
- Output voltage ripple: < 40mV at 200mA
- Buck-boost topology allows the input to be above, below, or equal to the outputs
- iPhone app for use with Bluetooth Expansion
- Smart Power Supply Control Software – v1.2
Use the Smart Power Supply application to control the Hydra. Currently available only for Windows machines (XP, Vista, 7, 8). (NOTE: The Smart Power app requires .NET 4.0 or later framework for Windows. If you have Windows XP, you’ll need to install .NET 4.0 because Microsoft chose not to support .NET 4.5 for XP)
- Driver download for Windows, OS-X, and Linux
You’ll need to install the appropriate drivers to connect to the Hydra from your computer.
- The CHR Serial Interface can be used by advanced users to configure the Hydra at the register level and to plot and log data in real-time.

The UM7 is a 3rd-generation Attitude and Heading Reference System (AHRS) that takes advantage of state-of-the-art MEMS technology to improve performance and reduce costs. Like its predecessors, the UM7 combines triaxial accelerometer, rate gyro, and magnetometer data using a sophisticated Extended Kalman Filter to produce attitude and heading estimates.
The UM7-LT is equivalent to the UM7, except that it does not include an enclosure and factory calibration is not available.

Extra cable assemblies for the UM7. The UM7 comes with one 5-pin cable assembly for the main IO header. Additional cables are not needed unless you want extras, or you want to use the 6-pin IO expansion headers.
