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
