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

Size of the PCBs: 49mm x 33mm

You can get a kit for the RF or RS485 development boards.
