Servobot Specs and Features

General -

Large 2" diameter x 1" wide wheels for great traction on any surface
3/4" swivel wheel on back to maintain balance
Tactile switches with "bumpers" up front for object detection
270 point experimenters board, to test your own circuits
Onboard Buzzer
On/Off Switch with JST connector to battery, no need to remove the battery for recharging, just unplug it from the switch and plug it into the charger.

Circuit Features-

- Power is brought in through a bridge rectifier, so even if you hook the power up backwards, you cannot hurt anything.
- Power for the PIC is supplied through a 5v regulator
- Power for the servos comes directly from the batteries, so it is not recommended to use anything higher than 7.2v or you could burn out the servos
- The PIC is mounted in a ZIF socket for easy removal/insertion when reprogramming
- All I/O pins from the PIC have been brought out to standard MTA style headers
- The servos, buzzer and LED eyes are hardwired into the circuit and are controlled from PORTB of the PIC, this leaves PORTA for interfacing your sensors (the tactile switches are connected to PORTA) doing it this way gives you the option of replacing the Pic16F628 with the Pic16F88 to allow you to use the analog inputs on PORTA
- All the PORTA pins have weak pull-ups that can be enabled with a dip switch, there are also two spare pull-ups for use with other peripherals.
- Provisions have been made to use an external resonator or use the internal clock and use the pins as standard I/O pins
- There are three 5v power connectors on the board for use with external equipment, one at the back by the voltage regulator and two up front, one of which is current limited. You can also get straight battery power from any unused servo header.
