msPROBOT PCB Started

The only thing routed so far is the lithium battery charger. Most of the chips I am using have a recommended PCB layout so I am going to follow those to reduce noise from the switching power supplies. Board is going to be 75mm x 160mm in size. Should only cost $3 per unit to get them made in bulk.

msPROBOT Schematic Done

I just finished the schematic for the msPROBOT.

Added the the design is the lithium battery charger and protection circuit, the motor encoders, and a 3.3V to 5V bidirectional voltage level shifter. The level shifter will make it easier for users to add extra components and sensors to the robot. The 3.3V and 5V I/O lines are broke out to headers on the board.

A Wild Robot Platform Approaches!

So I have a new robot platform coming out soon. It will be ready for Maker Faire next month. There is not allot of choices for MSP-430 Launch Pad robots so this is meant to fill the gap.

So far just the 3 power rails. 3.3V for the MSP-430 Launch Pad, 3V for the motors, and 5V for sensors. It will come with a lithium battery and charger circuitry. Motor encoders and a line follower sensor will come on the robot stock. Will be programmed to do line follow out of the box. The mounts will be all 3D printed and the PCB will be offered for sale separately. Mounting points will be all over the board to it will be easily expanded.
