3. Motivation

4. System Overview

5. Ground Link USB to SPI chip provides virtual COM port Could also be a microcontroller Provides Data arbitration Full Duplex Link 3 MSP430 microcontrollers 5 watts max power TX 440Mhz Operation Digital Link up to 500kbaud Adaptive Frequency and Baud Hardware forward error correction

6. Ground Link 4 MSP430 microcontrollers Provides data arbitration and signal routing Full duplex ground link Same as Ginger Prime 4AH li-poly Single Cell

7. Allspice Nodes 2.4Ghz @ 1mW TX Single duplex Folded dipole PCB antenna ~20mA active current 500kbaud max data rate Keeps track of capsules and data routing (between capsules and from ground to capsule) 1 MSP430 Allspice nodes can interface via: I2C SPI TTL UART (RS232, TTL levels) Each capsule assigned a 3 letter callsign
