A new high quality “no-compromise” power regulator and parametric measurement tool has been launched via Kickstarter this week in the form of the Abbycus V Series, designed specifically for the Raspberry Pi range of single board computers. Designed by electronic and mechanical design engineer John Hoeppner the Raspberry Pi HAT is capable of generating a stable and accurate power supply from low-cost poorly regulated power supplies such as AC adapters, phone charges and others. Making sure that your power supply is always perfect for the Raspberry Pi.
It’s creator explains more about why having a constant quality power supply is important when running your Raspberry Pi. “Computers and their attached peripheral devices have a low tolerance for inaccuracy, noise, and sudden voltage changes. It is essential to use a stable voltage source to prevent unpredictable behavior. There are two models of the V series that address different needs. Both modules stack directly on top of a Raspberry Pi (any model with the 40 pin GPIO header) and conform to the Raspberry Pi HAT (Hardware Attached on Top) specifications.”
– V8 Power generates high quality and stable power for the Raspberry Pi. The high current / high efficiency (low heat generation) switching regulator provides clean and accurate 5V power for the Pi and peripheral devices. Standard features include over-current and short circuit protection, high temperature current limiting, reverse polarity protection, and a reset-able PTC type fuse. Two high current switched 5V outputs are included to control external devices (LCD or ?). The V8 also features safe power ON/OFF to prevent data corruption. Additionally a brushless ball bearing DC fan mounts directly above the Raspberry Pi CPU providing excellent cooling under high stress conditions.
– V12 Power inherits all the features of the V8 plus the following: 1) Precision measurements of voltage, current, and temperature. 2) Active cooling with variable speed fan control. 3) Supports battery operation – displays the charge state and voltage of the battery source, and enables safe low battery shutdown. 4) Raspberry Pi CPU statistics are monitored and displayed. 5) One-button safe power ON/OFF. OLED display for parametric info. 6) Built-in ‘Arduino’ compatible micro-controller. 7) A class D stereo audio amplifier drives two speakers. 8) Open source code for easy user reconfiguration or customisation.
For full specifications on both the V8 and the V12 Raspberry Pi power HATs jump over to the official Kickstarter crowdfunding campaign page. Below is a brief summary of the features you can expect from the power HATs
– On-board regulator supplies 5V @ 5A to the RPi and attached peripherals.
– Short circuit, over & under voltage, and thermal protection.
– Two high current switched 5V power outputs for external LCD and back-light (or ?).
– Reverse polarity protection and reset-able PTC fuse.
– Safe power off to prevent data corruption.
Features specific to the V12 Raspberry Pi Power HAT
– Voltage measurement of the internal 5V regulator, external input voltage, and the RPi 3.3V I/O.
– Current measurement for the RPi and its peripherals (LCD, USB add-on’s, etc.).
– Temperature measurement from on-board sensor (ambient or case temperature).
– Monitors and displays Raspberry Pi CPU temperature, clock frequency, and core voltage.
– Fan speed control uses either on-board sensor or RPi CPU temperatures.
– OLED display shows all system parametric data in several scroll-able ‘screens’.
– ‘Arduino’ compatible embedded micro-controller allows DIY customization.
– Open source Arduino code and OS Python service scripts.
– Audio class D amplifier can drive two 8 ohm speakers up to 3W.
– Error detection, reporting, and shutdown action (see Error screen below).
