msPROBOT Ver 1.0 Released!

After a whole weekend working on the PCB I finally finished Ver 1.0 of the msPROBOT. The robot is completely open source. So far just the PCB is designed. I will be adding the bracket files and then full assembly instructions. If all goes to plan the msPROBOT will make an appearance at Maker Faire next month.

I will launch the project page in a couple hours. Need a short break first though.

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.
