This controller is designed for people who have an understanding of PIC
microconrollers, associated peripherals and general PWM techniques, It is not
suitable for the beginner or novice unless used with pre-loaded firmware such as the HexEgnine. |

| Description |
The p.Brain-ds24 has be designed for use in advanced hobby robotics, where multiple R/C type
servos need to be controlled with a standard PWM signal, such as hexapod robots. At the core
of the p.Brain-ds24 is a microchip dsPIC33F 16bit micro controller with 128Kb programme
flash, 8Kb RAM and 32Kb external EEPROM. This micro controller can be programmed using
microchips ICD2 programmer and MPLAB IDE. Although the micro controller can be
programmed in assembler, I suggest using a C compiler such as Hi-techs (www.htsoft.com) All
programming examples are written for the Hi-tech compiler.
The p.Brain-ds24 has 24 PWM channels for R/C servo control, along with a variety of other peripherals such as UART's, I2C, SPI, ADC, Digital I/O, which are all brought out to two 24 pin,
0.1” pitch headers. The p.Brain-ds24 can then be plugged into a motherboard to distribute the
PWM signals and peripherals accordingly such as micromagic's “p.Brain-SMB” or a user defined
motherboard. The p.Brain-ds24 has an on board 3.3V regulator, and can be run from 4 to 9V
on the VIN pin. There is a 3.3V pin on one of the 24pin headers to take a small amount of
power for user peripherals. |

| Accessories |
Although you can design your own motherboard for the p.Brain-ds24, we suggest purchasing a p.Brain-SMB base board for convenient development and testing. The p.Brain-SMB can be fitted with a RJ11 6/6 socket for easy connection to Microchip's ICD2 prgrammer/debugger.
