= about RaspberryHabu * Addon board for Raspberry Pi. * Stackable or connect by cable. * DIGITAL INx6, DIGITAL OUTx8, ANALOG INx8, Power Circit, RTC * Except RTC IC, It is composed by DIP parts. Even an amateur is easy to assemble it. * It is released in FABLIB. Anyone use it's blueprints in free. Anyone can manufacture from it. Anyone can sell it to anyone. Freedom! * The license is CC BY 0. You crib it and make it for one's product and change it and am OK. * FABLIB project in itself prepared as an original kit and am selling it. * The argument about the development reaches in Japanese Raspberry PI Users Group ML mainly now. https://groups.google.com/forum/?fromgroups#!forum/japanese-raspberry-pi-users-group == concept * Than a function inexpensiveness * Than performance solidity * Than gaudiness plainness == target * It is for education, but It not for the training of the professional engineer. * I aim at what It can be handled without electric knowledge. * For education of the software, handling motivates a physical device. * Therefore I make a working board if I tie it == daily necessity * Incentive to be able to make daily necessity with the smallest trouble * The premise that is usable only for the experiment such as the breadboard eliminates it. * I enter problems of Raspbery Pi in itself and raise general completeness, if necessary. * The connection layout that attached great importance to heat radiation of Raspberry Pi * Power supply supply via the AC adapter * The deployment of the real-time clock = The inexpensiveness is justice * Price setting not to chip learning will * 5x10cm size. A deep-discount board manufacturer is available. * Amount of money that a child can purchase by oneself * Parts cost price is 33%. * Hardware sale without the unreasonableness is possible. * When I purchase it, and only a board prepares parts by oneself, it is cheaper. == robustness * A buffer, the transistor array are implemented by DIP parts and an IC socket. When it was broken, I can change it by oneself. * Big voltage tolerance. I incorporate a buffer even if I do wrong wiring so that damage is inferior as possible to the main body of RaspberryPi. = For practical use * Reinforcement of the power supply * It receive supply of the electricity from Raspberry Pi, but RaspberryHabu can attach power supply circit and can usually do it with more stable movement with this * RTC * Battery backup is with it == plainness * I adopt a row in WiringPi. * I adopt a sauce-based signal. Logic 1-High-5V, 5V-High- logic 1. * The digital input of a wide voltage range. A direct signal can input 3.3V system, 5V system, 12V system of the car without an additional circuit. * The digital output with ability for big drive. It can drive high brightness LED and a relay without an additional circuit. In addition, ON/OFF of the 100V system is made by going through a relay. * An intuitive board layout. I place internal placement and connector sequence by intuition clearly. * I adopt an intelligible relay as a switch not a motor driver. = Function == digital IN * 6 ports * Input range 2V - 15V == digital OUT * 8 ports * Output 5V == analog IN * 8 ports * 5VMax, 3.3VMax choice == power supply circuit * 5V supply * I separate interconnection / with Raspberry Pi, and setting is possible == RTC * Battery backup == serial connector * It is for serial adapter connection * RaspberryPi bus direct connection type (201305xx version) * 5V level conversion type (201306xx version ~ ) = Bus wiring for function cutting apart, relocation * WiringPi sequence == and others * DC Jack for AC adapter connection * Jumper for VCC voltage setting * VCC monitor LED * DOUT bus monitor LED x 4 * DOUT connection small size relay x 4 * Switch-on board implementation for DIN experiments * Bus for ANALOG IN sensor power supply * Bus for DIN signal power supply * GND bus for DOUT load connection * Infrared LED array (a relay and exclusion use) = Version == 20130513 * 1st release * The version that put a regulator on a power supply section * I sell it by events === source * http://sourceforge.jp/projects/fablib/scm/git/RASPBERRYHABU/commits/d17f548d40c7025e207bf4f9516e25d13c45cad9 === connection diagram * http://sourceforge.jp/projects/fablib/wiki/RaspberryHabu/attach/RASPBERRYHABU_20130513.pdf === assembling commentary * How to build add-on board RaspberryHabu http://togetter.com/li/509049 for RaspberryPi * How to build add-on board RaspberryHabu -
