Finally, after several weeks delay, the new PCBs for the Mini Sumo Robots (see “Zumo Robot with WiFi and GPS”) arrived, and best of all: first test are all running fine :-).
First PCB under Debug
Beside of smaller bug and layout fixes, the new PCB features the following extensions:
- Additional user LED (now two) on the back
- Simpler and easier connection to the motor and quadrature encoders
- Bluetooth and nRF24L01+ connectors on the base board
The boards came with four boards on a bigger board:
Four Boards Bottom Side
Four Boards Top Side
With the exceptions of the Arduino Shield compatible headers and the reflectance sensor header, the boards have all the parts populated which is a big time saver in the course.
Sumo Robot Board Components
For the motors we are using now a micromatch cable:
Micromatch Cable with Motors
Encoders with Cables
Motors connected to Board
Hopefully, everything comes together as planned ;-).
Happy PCBing 🙂

Please tell me I can buy this!!! This is exactly what I was searching for. I have a build project planned but haven’t seen what I wanted until just now. I am wanting to step into the world of mbed and think the zumo is a awesome build platfor.

Students of my class can buy it 🙂 But I’m open to that idea (of course, students come first!). Please contact me with under the email address on the About page of this blog.

And all hand soldered by the students, too. What progress they have made in a couple of weeks!

Yes, they learn fast, believe it or not ;-). There are still a few things they need to solder on that board, I just do not want to make it to easy 🙂
