Picaxe Board with very small dimentions: 2.1x2.1x2.6cm (0.826x0.826x1.023inches)!
Board was Updated! Version 2.0 is done. :) I have created this small Picaxe08M2 Board so it can be integrated in small robots or other projects which require small … Read more

Creating a new Arduino PCB in the Arduino IDE - Trials and Tribble-ations

If someone can help me out then I will write a tip/walkthough on this subject.

Quite often DAGU products use the ATmega168 MCU rather than the ATmega328 because they are a bit cheaper and 16K of program memory is often enough.

The problem is that ATmel no longer produce the ATmega168 20-AU which we had been using. They now produce the ATmega168PA which is almost identical but has a different device signature ID.

Channel Breakout, Power Breakout Boards

 

Power Breakout Board, comes with mosfet polarity protection. No onboard regulator, intended for projects that have a dedicated high wattage supply already (no puny 7805).

 

 

Channel breakout board, supports up to 16 ports (Supports servos too), and powered by the connector on the right hand side, therefore you can power them off their own dedicated supply.

Dual 18F4620 board with supporting 18F2525 for display

Right now I am working on my master-slave-slave board that will suit my needs for a long time. It has a master 4620, that communicates to another 4620 for processor assistance.

 4620 MASTER: Spaces for 5 servos, rs232, I2C, sn754410 motor controller, 8 ADC channels, 2x5 header so it is expandable into another board.

4620 SLAVE: Setting switches, proximity IR sensors (8 for complete sensing), speaker, encoders (rear and front for a car drive bot, left and right for 2 wheel operation), 38khz IR led driver, bumper switches and spaces for 6 servos I2C.
