Core system constrains:
ADuC based design
wireless communication with other devices ( e.g. Bluetooth )
In-System-Programmable
System status indicators ( e.g. Power, Status, Bluetooth [not] connected )
small connectors
small formfactor
precision timesource ( onchip / quarz )

2007.02.20
Overall system constraints:
I²C Busmaster
RS485 network interface
Single LiPo cell supply
simple charging system
One-Sided design - all components on one side
Flat overall design
3.3V system operation voltage
RS485 Sensor Network interface ( via UART )
ISP via programming-interface compatible with original ADuC DevKit serial adapter

Piggyback-Solution:

Motherboard with Bluetooth and ADuC

Daughterboard with task-specific periphery and powersupply on-board

Daughterboard double sided PCB only

---

Wishlist:
System Status LED's optionally fittable on core modules backside
Two switches optionally fittable on core modules backside
3.3V RfID ( although not on-board )
Fuelgauge for fixed batteries
up to 12V/14.4V power supply
=> Wide range of power-supplies / input voltages
Powerswitch-capability to power down external components
SPI Bus
DAC's
ADC's
GPIO's
1-Wire Busmaster
USB-Charging - ideally with power-consumption announcement on the USB-bus
USB-Functionality
