====== Node Development Hardware ====== To create basic bus nodes small development boards were designed. They are small PCBs with cheap SMD components which can be easily integrated into own projects. Components: * Controller: ATMega164, ATMega324 or ATMega644 * 18MHz xtal * RFM12 module or RS485 transceiver * 2.5V voltage reference for ADC * RS485 version: 5V, 200mA switching regulator (LM2574, LM2594, LM2674 depending on availability and cost) * RF version: 5V linear regulator * 2.54mm connections for integration into own projects * RS485 version: One RJ45 connector * RF version: Pads for a SMA antenna connector * ISP connector * one current output for motors or lights ===== RF Version===== {{:uberbus:dev-rf-ecke-ant.jpg?400|}} Size of the PCBs: 49mm x 33mm ===== Kits ===== You can get a kit for the RF or RS485 development boards. ^Version^Price^ | RF | 15 Eur | | RS485 | 17 Eur | === colorcodes of smd parts - RS485 kit === ^ Wert ^Bauform^ Farbcode ^ | 100nF | 0805 | rot | | 22pf | 0805 | blau | | 330ohm | 0805 | grĂ¼n | | 220Kohm | 0805 | rosa | | 1Kohm | 0805 | gelb | | ? | 0603 | braun | ===== Build instructions ===== TODO ======= Bridge Hardware ====== Currently only the moodlamp can act as a bridge to a computer.
