Brick Buddy 3 - A Start

 

This is a scaled down version of Brick Controller 2. This chart shows the major differences.

Why this?  Well I needed something smaller that I can put inside as many modules.  There are at least three module that only need two motor controllers.  This replaces the very small individual LED connectors with a 2mm socket, two of  them.  Thus you can use individual 2mm pins or one of the attachment boards I have.  (More on this later)

The other major difference is the processor.  This board uses the PIC 18F series instead of the PIC32.  While there is a USB connector, the PIC is connected via a standard serial (RS232 port).  Right now I have four processors that will fit this board.  All of them can be bought is some form (mostly differences in FLASH Program memory).  This is as opposed to the PIC32 in BC2, which is almost impossible to buy.

Finally the Bluetooth was changed to a 5.0 version.  The RN4020 was hard to find and was stuck at 4.0.  The RN4871 is also hard to find, but I have enough to at least prove out the design.

The design is done and I am in process to get the PCB made and some assembly done.  More as we progress.
