p.Brain-ds24

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 µ24-HexEgnine.

The p.Brain-µ24 essentially combines the p.Brain-ds24 and p.Brain-SMB into one convenient and compact package.

Price

Description
The p.Brain-µ24 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-µ24 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-µ24 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 0.1” pitch headers. The p.Brain-µ24 has an on board 3.3V regulator for logic, the regulator supply can be run from 4 to 9V on the VL terminal. The VS terminal is for servo power, this depends on the servos iused but is usually 4.8 or 6.0V DC. The VL terminal can be connected to the VS terminal for single source opperation useing JP2.
