This page links to information about various products we have had under
development over the years; they may appear in the future under our Nubotics
product line in some form or other. However, they are currently
no longer available.

This useful little board (< 4 square inches) can
drive two brushed DC motors at up to 1.1A per motor with motor supplies
up to 36v. Each motor has independent PWM, Direction, and Brake signals.
Signals can be jumpered to save I/O on your micro controller.

Powerful and compact, the Lil'PICcy is perfect for controlling
a small, two wheeled robot. It includes the same motor drive capability
as our FlexDrive product, plus a lot more:
- Microchip Technology's PIC 16F873 or 16F876 microcontroller
- two general purpose LEDs
- one power indicator LED
- two general purpose DIP switch inputs; useful for controlling
the operating mode of your robot
- two Sharp IS471F IR proximity sensors plus matching IR LEDs
- flexible power supply design - single or dual supplies; regulated
or unregulated
- DPDT power switch
- 4 extra 74HC14 Schmidt Trigger inverters for signal conditioning
- 8 undedicated I/O lines, offering A/D conversion, digital Input
or Output, Timer/Counter inputs, and interrupts
- 5 pin ISP (In Circuit Programming) connector
- 4 pin RS232 (TTL-level) connector; mates with our SerialIF board

This daughter board for the Lil'PICcy enables you to
interact with your robot using a standard straight-through 9 pin serial
cable and any terminal program on your PC. Suggested uses include:
- uploading new firmware using a third-party bootloader
- debugging your firmware by displaying internal data and specifying
parameters

This simple 3 sensor board lets the Lil'PICcy detect
the edge of a microsumo ring. It also allows it to follow a line.
- uses 3 Hamamatsu P5587 IR emitter/detector pairs
- simple interface to any microcontroller
- outputs are already signal-conditioned
