THE PARTICLE COMPUTER DOCU
                    (Particle Computer - the wireless core)                   

 

Particle Core Board (version 2/1x)   

The particle computer is the heart of all the components in the system. It is designed to be a light weight, small, low power and mobile platform to develop applications and interfaces for ubiquitous, pervasive, ambient, wearable, sensor network,. Computing. It is equipped with a 125 kBit Rf module, the TR1001. It carries an external 32K EEPROM controlled over I2C/ 512 K Flash controlled over SPI (AT45DB04B). It is based on the PIC 18f6720 Microprocessor from Microchip. The PIC carries 128k of ROM, 4k of RAM and included various modules like 2 hardware UARTS, Analog/Digital Conversion, SSP, PWM and lots more.

The RF Communication is based on AwareCon, the wireless ad hoc protocol for the particle computer. The particle computer can be powered through the 2pin MOLEX connector with voltages from 0.8 to 2.5 Volt. It can also be powered through the 21 Particle connector (type CONAN) with a 3.3V regulated supply. The pins on the CONAN connector represent a freely programmable interface to the particle including I2C lines, Digital I/O, analog I/O and any other busses that can be implemented in software. Detailed information how the pins on the Processor on the Particle Board are used are listed below.

The device is freely programmable. The developer section provides software as operating system and low power, high efficient network stack that simplyifies development but the Particle board is not restricted to this functionality.
